array to be hosted near ESO’s Paranal Observatory in…" +date: 2018-12-18 +category: news +author: CTAO +cover: /uploads/Council-768x432.jpg +draft: false +--- + +The 15th meeting of the CTAO Council was held 13-14 November in La Palma. The location was very suitable considering that on October 10, the LST telescope prototype was inaugurated on the Observatorio del Roque de los Muchachos, the northern hemisphere site of the CTA Observatory. This gave the delegates the opportunity to admire the first impressive instrument of the “family of 118” that shall constitute the largest system of telescopes ever constructed in the world. Within this festive atmosphere, which contributed to an excellent collaboration with our colleagues from the Instituto de Astrofísica de Canarias, the Council dealt with several crucial topics and made decisions that will mark and consolidate CTA’s future. It was also a meeting of transition in the Council governance: Gabriel Chardin was re-elected as Chair for another year and Markus Schleier succeeded Giampaolo Vettolani, who completed his mandate as Vice Chair. We are very grateful to Giampaolo for his contributions to the Council in his service as both Chair and Vice Chair since the Council’s inception. + +An important highlight from the meeting is that we saw the investment in CTA continuing to grow. Both Australia and Poland signed the Memorandum of Understanding for the construction of CTA, thus formally reinforcing the existing involvement of their scientific community and enlarging the international participation in the CTA project. A significant consequence, jointly with the increased commitment of France, is our advancement toward the threshold funding: we have reached 94% of the 250 M€ goal. Additionally, the Swiss government expressed the intention to increase its contribution in the next two years. + +Finances were a major focus of the meeting. Beyond the nomination of the company auditor for the year 2018 and the standard report on the current budget status, we discussed the 2019 budget extensively. As a result, the funding agencies have approved to contribute a consistent increase of about 4 M€ in 2019, well beyond the 2.4 M€ of 2018. This will allow the management to further develop the recruitment campaign necessary to reach the critical size of staff to prepare and manage the construction phase. The CTAO has grown from 16 members (January 2018) to 30 (expected in January 2019), with the objective to reach 60 members by December 2019, including staff for CTAO Headquarters, the Science Data Management Centre and the CTA-North site. + +In an effort to continue our progress toward construction, I proposed a new pathfinder strategy as an approach to advance our technical progress on CTA sites. According to the statutes, CTA construction can only start with the advent of the final legal entity (the CTAO ERIC); which challenges us to address our transition to an ERIC while simultaneously continuing the progress of the various project phases. With the pathfinder strategy, CTAO can enter an agreement to install an instrument on site, at the contributor’s cost, for testing purposes without the CTAO making a decision about the final technical design and executing an In-Kind Contribution (i.e. a pathfinder may have to be removed from the site). The new pathfinder strategy was well-received by the Council. + +As for the status of the CTAO ERIC, we have seen great progress in 2018, with several meetings taking place that have pushed us steadily toward our new and final legal entity. At the Council meeting, a legal consultant presented an analysis that was very reassuring about the tax conditions and transfer of assets to the CTAO ERIC, and it seems this matter will not be a showstopper to the process. + +And, finally, perhaps one of the most important themes for the future of CTA has been the evolution toward the signature of the agreements that will allow for the formalization of the ESO site as the location of the CTA-South array. Thanks to the strong  and positive intervention of the ESO Director General, we have been able to solve the residual impediments rising from some formalities related to the ERIC application, and which put us in the position to sign the three lateral agreements in Santiago, Chile during the week of 17 December! diff --git a/src/content/news/acada-software-system-passes-its-critical-design-review.md b/src/content/news/acada-software-system-passes-its-critical-design-review.md new file mode 100644 index 0000000..1ff63d2 --- /dev/null +++ b/src/content/news/acada-software-system-passes-its-critical-design-review.md @@ -0,0 +1,23 @@ +--- +title: "ACADA Software System Passes its Critical Design Review" +description: "On September 23, the CTAO ACADA Collaboration achieved yet another milestone when the CTAO Central Organisation officially approved and closed out the Critical Design Review (CDR) of the Array Control and Data Acquisition (ACADA) system.…" +date: 2024-10-04 +category: news +author: CTAO +cover: /uploads/Screenshot-2024-10-04-at-12.17.16-768x432.png +draft: false +--- + +On September 23, the [CTAO ACADA Collaboration](https://www.ctao.org/emission-to-discovery/data-and-computing/) achieved yet another milestone when the [CTAO Central Organisation](https://www.ctao.org/organisation/team/) officially approved and closed out the Critical Design Review (CDR) of the Array Control and Data Acquisition (ACADA) system. The approval of the CDR, an in-depth evaluation to ensure the system design meets all the requirements of the Observatory, marks a new phase in the project, moving from testing to integrating the advanced software packages that will operate the arrays. + +The ACADA system includes all the software responsible for the supervision and control of telescopes and calibration instruments at both CTAO array sites. The system ensures that the execution of the astronomical observations is accurate and efficient, managing the data acquisition and compression of the raw data, handling science alerts to automatically rearrange the observation schedule and to inform other observatories of interesting gamma-ray events, and providing the user interface for the site operators and astronomers. Thus, as an orchestra director guides the different instrumentalists to produce music, the ACADA software controls a great variety of sub-systems to make the telescopes and support instruments operate together harmoniously to allow the data to flow. + +Developing such a complex system requires many steps or “releases.” Getting to this point with ACADA, alone, has been the result of around 40 people from 10 institutes from six countries working together over the past 4-5 years to prepare and test the software to ensure it is ready to be used by the CTAO. To evaluate the first release, members of the ACADA Collaboration traveled to the [CTAO-North](https://www.ctao.org/emission-to-discovery/array-sites/ctao-north/) site in La Palma, Spain, in September-October 2023 to carry out [two separate integration campaigns](https://www.ctao.org/news/major-telescope-operations-milestone-with-acada-integration/) with the [Large-Sized Telescope (LST)](https://www.ctao.org/emission-to-discovery/telescopes/lst/) prototype or LST-1, in cooperation with LST Collaboration experts. The campaigns, [documented in a series of interviews](https://www.youtube.com/playlist?list=PLqd_CmPv1afbrmKxp2hJarvTgFVXq8ysB), were a complete success, exhibiting that the system could operate a telescope as expected and allowing researchers to identify and solve minor issues.

The project, conceived by the international organization [GalileoMobile](http://www.galileo-mobile.org/) and the [Asociación Canaria de Amistad con el Pueblo Saharaui](http://www.acapscanarias.com/) (ACAPS), consists of a combination of outreach activities and visits to the Canary observatories with the children in July and August as part of  their summer in the Canary Islands with the “[Holidays in Peace](https://www.fmreview.org/peopletrafficking/crivello-fiddian-chatty)” program. The project will also include a visit to the refugee camps by a group of scientists and experts in October. The Cherenkov Telescope Array Observatory (CTAO) is one of the participating partners in this project, supporting the organization of activities and the provision of educational material for the camp visits. + +AMANAR, which means “Pleiades” in Berber, was born as an outreach project to inspire the Saharawi community through the observation of the Universe and the development of scientific skills, as well as to promote peace, common understanding and a sense of world citizenship under the same sky. The project, conceived by GalileoMobile and ACAPS, was selected as a “Special Project” within the International Astronomical Union’s (IAU’s) [100th Anniversary activities](https://www.iau-100.org/). It is co-funded by the [Instituto de Astrofísica de Canarias](http://www.iac.es/index.php?lang=en) (IAC) and the IAU’s Office of Astronomy for Development and counts on the collaboration of CTAO, Gran Telescopio de Canarias (GTC), Virgo Collaboration , IAU’s Office for Astronomy Outreach, IAU’s Astronomy Translation Network, Galileo Teacher Training Program (GTTP), Cielos de La Palma, Asociación Canaria de Solidaridad con el Pueblo Saharaui (ACSPS), Fundación Observatorio de Temisas, Agrupación Astronómica de Gran Canaria, Asociación Astronómica AMNIR, TITSA and CEIP Juan de Zamora. + +The summer activities in the Canary Islands within the “Holidays in Peace” program will be carried out in Tenerife (July 20), La Palma (27 July) and Gran Canaria (August 3). In Tenerife and La Palma, the Saharawi children will join us in a visit to the observatories, where they will get an up-close look at some of the telescopes, such as the Large-Sized Telescope prototype (LST-1) located at the El Roque de los Muchachos Observatory (La Palma). Moreover, the group has crafted educational and outreach workshops for the children to inspire their interest in the Cosmos and develop their creativity. These activities include designing a new telescope to catch gamma rays and learning about the Solar System, among others. CTAO Outreach and Education Coordinator, Alba Fernández-Barral, and the Outreach and Communication Officer, Megan Grunewald, have actively participated in the organization of activities for these two sites and will join the group on these dates. The last activity will take place in Gran Canaria, in the Juan de Zamora school (Arucas), where the Saharawi and local children will learn about astronomy and will enjoy the night sky together. The astronomical program within the “Holidays in Peace” is expected to continue for the next three years. The project will close this year in October with a visit to the refugee camps in Tindouf, where scientists and experts from different organizations will carry out workshops at schools and will study and disseminate the astronomical knowledge of the Saharawi population. + +“The project has a long-term goal of contributing to raise awareness, at the national and international level, about the hard conditions that the Saharawi people must live in the refugee camps, which has lasted already for 40 years. To do so, we will create different audiovisual materials, such as an immersive video and a documentary, with which we will give a voice to the participants and disseminate their message of peace and social justice,” explains the main organizer Sandra Benítez Herrera, astrophysicist and science communicator at the IAC’s Communication and Scientific Culture Unite (UC3) and member of GalileoMobile since 2011. “The institutions collaborating in the project have committed to help in this sense, too.” + +The CTAO’s participation is within the framework of its own Astrodiversity program. The CTAO is a global organisation proud of its diversity that aims to become a reference of equity and respect in science, as well as to work internationally to achieve equality in our field.

This discovery was the initiation of *TeV astronomy*, which, with its rapid growth, has led to the detection of about 200 gamma-ray sources from other ground-based detectors like H.E.S.S., MAGIC and VERITAS and has paved the way for the next generation: the Cherenkov Telescope Array Observatory (CTAO). + +Because gamma-rays never make it to the Earth’s surface, these instruments use the Imaging Atmospheric Cherenkov Technique (IACT) to detect the by-product of the gamma-ray’s interaction with the atmosphere: Cherenkov light. The interaction produces cascades of subatomic particles – these highly energetic particles can travel faster than the speed of light, which causes a faint and extremely short (of the order of a billionth of a second!) flash of bluish light. Cherenkov telescopes, since the very beginning, have been built following a typical optical design where the light is reflected off the telescope’s mirror to be captured by the camera and then is converted into an electrical signal that is digitized and transmitted to record the image of the light. + +The Italian National Institute for Astrophysics (INAF) is leading the ASTRI (*Astrofisica con Specchi a Tecnologia Replicante Italiana*) project aimed at the design, deployment and implementation of a novel end-to-end prototype telescope that is proposed for the CTA Small-Sized Telescopes (SSTs). This Cherenkov telescope, named ASTRI-Horn (in honor of Guido Horn d’Arturo an Italian astronomer who first proposed in the past century the technology of tessellated mirrors for astronomy), is adopting a wide (10°x10°) field *Schwarzschild-Couder dual-mirror *optical configuration and is equipped with a specifically designed, innovative Silicon photo-multiplier (SiPM) camera managed by very fast read-out electronics. The ASTRI-Horn prototype, located on Mount Etna (Italy) at the INAF “M.C. Fracastoro” observing station, has been conceived as an end-to-end project including the full data archiving and processing chain, from raw data up to final scientific products.[/vc_column_text][vc_column_text]The observations of the Crab Nebula were carried out between December 2018 and January 2019, during the ASTRI-Horn telescope verification phase, for a total observation time of about 29 hours, divided in on- and off-axis source exposure. The camera system was still undergoing assessment, and its functionality was not fully exploited. Moreover, owing to recent eruptions of the Etna Volcano, the mirror reflection efficiency was partially reduced. In spite of such camera and mirrors limitations, observations yielded the detection of the Crab Nebula with a statistical significance of 5.4s above an energy threshold of about 3.5 TeV, definitively probing the new technologies and opening a new era for IACT. + +“The result obtained by ASTRI is an important milestone for the IACT technologies. It is demonstrating that the dual mirror configuration, firstly proposed by the great German Astrophysicist Karl Schwarzschild more than a century ago, is performing well. It is now possible to achieve a very large field-of-view with a much more compact Cherenkov telescope design, easily observing very energetic cosmic gamma-rays up to a few hundreds of TeV” says Giovanni Pareschi, astronomer at the INAF-Milano and principal investigator of the ASTRI project. + +Three classes of  telescope are required to cover the full CTA energy range (20 GeV to 300 TeV): Medium-Sized Telescopes (12 m diameter dish) will cover CTA’s core energy range (100 GeV to 10 TeV) while the Large-Sized Telescopes (23 m) and Small-Sized Telescopes (4 m) or SSTs are planned to extend the energy range below 100 GeV and above a few TeV, respectively. The ASTRI-Horn telescope is one of three proposed SST designs being prototyped and tested for CTA’s southern hemisphere array. + +“CTA has been exploring the dual-mirror technology since the very beginning of the project, and some prototypes have been realized using such an approach: the ASTRI-Horn and the GCT for the SST and the SCT for the Medium-Sized Telescope,” says Federico Ferrini, Managing Director of the CTA Observatory (CTAO). “The result obtained by ASTRI-Horn telescope is very encouraging and confirms the potential of technological advancement for Cherenkov astronomy.” + +The ASTRI project ([http://www.brera.inaf.it/astri/](http://www.brera.inaf.it/astri/)) is led by the Italian National Institute of Astrophysics (INAF) with the support of MIUR (the Ministry of Education, Universities and Research) and with in collaboration with a number of Italian Universities (including, Perugia, Padova and Roma Tor Vergata) and the Italian National Institute of Nuclear Physics (INFN), and the direct the participation of the Universidade de São Paulo (USP) and FAPESP in Brazil and North-West University in South Africa + +The Cherenkov Telescope Array (CTA) is a global initiative to build the world’s largest and most sensitive high-energy gamma-ray observatory with 118 telescopes split between two sites: one in the northern hemisphere on the island of La Palma, Spain, and the other in the southern hemisphere near Paranal, Chile. More than 1,400 scientists and engineers from 31 countries across five continents and more than 200 research institutes are participating in the CTA project.

The corresponding relation between “backscatter coefficient,” a measure of how light is getting back-scattered during its path through the layer, and the “extinction coefficient,” a measure of how light coming from sky sources is altered as it passes through the different atmosphere layers, indicates the presence of large diameter particles at the lower layer. A similar interpretation could be made when comparing the light extinction at two different wavelengths and deriving the so-called “Ångström coefficient.” This allowed to interpret the lower layer as a dust plume from the Cumbre Vieja volcano, while the upper layer is interpreted as a cloud with typical characteristics for La Palma atmosphere at those altitudes. + +These results are an important help for other profiling instruments at the Roque de los Muchachos Observatory, particularly LIDARs, to determine which part of their data can be attributed to the volcano dust plume and which is due to other weather phenomena.

It requires meticulous consideration of every aspect of building and maintaining the technology – from funding and foundations to software and safety – and the experience and resources to determine those requirements and plot the path forward. In the past six months, we have been making major strides toward putting all the pieces in place. Here is a summary of some of the main achievements and developments within the Project Office. + +Project Office Build-Up + +CTA is a very large project (in fact, the planned CTA Observatory with up to 120 telescopes on two sites is larger than any existing observatory today) so one of our biggest priorities has been ramping up the CTAO/Project Office, which means we have been vigorously recruiting technical staff. In particular, the Systems Engineering group has been strengthened in the areas of requirements and interface management, system safety and system validation and verification. Additionally, our first staff members have moved into the temporary Science Data Management Centre building in Zeuthen. We still need to strengthen our quality assurance, system integration, configuration management and documentation management so keep an eye out for those positions and more on our [Jobs page](https://www.cta-observatory.org/jobs). + +CTA Requirements + +As the requirements are the basis for the project, including those for the development, construction, testing, acceptance and operation of CTA, quite some effort has gone into complementing, revising and finalizing the requirements in the various areas. We have accomplished this through holding several dedicated discussions and workshops over the past year. Since September 2017, the Project Office has held discussions at Project Committee meetings and organized workshops for multiple areas, including OES, DPPS and SUSS. The top-level science requirements have been consolidated into one document and approved by the Project Scientist, and a document that establishes a standard Monte Carlo simulation framework for CTA has been updated and approved. Both documents, which are fundamental for CTA, were endorsed by the CTA Consortium Board in its meeting on 28 Sep 2018 in Berlin. + +CTA Simplification and Harmonization + +CTA will be a large science infrastructure with a large number of subsystems and units and a high degree of complexity. There are many good reasons to design and implement the simplest and most harmonized system possible. In fact, we are convinced that a high degree of simplification will be a crucial success factor both during construction and operation. This need for harmonization applies to many subsystems and components of the array. In the area of the three proposed Small-Sized Telescope (SST) designs (see below figure), harmonization is of very high importance due to the large number of units to be built, operated and maintained (70 in the baseline scenario). For this reason, the Council mandated that I carry out a procedure to arrive at a single SST design. Thus, the SST harmonization process is underway to decide on a single design for the SST structure, mirrors and camera, with the intention that all current teams will have a well-defined contribution to the final design. + +On 1 August 2018, a “Request for Information – SST Implementation” was issued by CTAO to the SST teams with responses received by 31 October. The responses will be provided to a panel of external experts, which will be asked to advise CTAO on the SST harmonization, taking into account science, engineering, operations and project management aspects. The panel composition and charges were approved by the CTAO Council in its 13-14 November meeting, and we envisage the SST harmonization review meeting to take place in early 2019. + +In-Kind Contribution Documents + +Preparation of the In-Kind Contribution (IKC) documents, the IKC Framework and the IKC Agreement template, has continued. After significant discussion, the IKC Framework document was approved by Council on 20 June 2018 and was provided to the work package leaders. This policy document outlines the rules for IKCs and will be an integral part of any future Call for Expressions of Interest and of future IKC Agreements. The IKC Agreement template draft was prepared by CTAO and is now being discussed by the Administrative and Finance Committee and In-Kind Review Committee. Assuming quick convergence, we aim for Council approval at the Spring 2019 meeting. + +Array Site Updates + +The Project Office, along with the IAC, have prepared the tender documents, including the scope of work for the first phase of the detailed project design for the CTA-North site. This first phase includes the design and construction of the remaining Large-Sized Telescope (LST) foundations and the first Medium-Sized Telescope (MST) foundation and the infrastructure for calibration equipment, as well as roads, power distribution and data networks. A European tender will be published to engage an architect and engineers to provide detailed designs and to undertake the necessary environmental impact assessments of the site. All applications will be reviewed and approved by the local authorities of Villa de Garafia and Cabildo de La Palma prior to starting any form of construction on site. If all goes as planned, the planning approvals should be completed by mid-2019 with the initiation of work on site before the end of 2019. Additionally, the CTAO is in the process of hiring a CTA-North Site Manager and should have a candidate on board very soon. The negotiations for the CTA-South site have concluded, and we plan to start infrastructure detailed design work in 2019. + +Construction Schedule + +We are working hard to collect all the information we need to build a credible and realistic construction schedule. For this, a firm basis is needed in the areas of requirements, system definition, system interface definitions, technical readiness, cost estimate and available funding, among other things. Work has started and is ongoing on the CTA system design, sub-system and interface definitions and cost book update. We are aiming to have the major construction milestone dates defined around March 2019, although the final schedule will depend on the time scale for creating the construction legal entity ERIC.

Bibha Chowdhuri was born in 1913 in Kolkata, in erstwhile British India, into a family of social reformers. The prevailing culture of religious dogmatism and social discrimination at the time prevented women from receiving any education. Amidst such cultural stigma, Bibha’s education was made possible by her progressive upbringing, which enabled her to obtain a Master’s degree in physics from the University of Calcutta in 1936, as the only female student in her class. Later, she would become the first Indian woman to pursue a Ph.D. in physics. These achievements, however, did not mean she had an easy path ahead in her quest to find a position after graduation. It was only after a lot of persuasion, that she was hired to be part of the new cosmic-ray research group of Prof. D.M. Bose in Kolkata. + +Bibha’s arrival to the research world came when fundamental particle physics was making rapid progress. In an era before the advent of human-made particle accelerators, cosmic rays coming from outer space were the principal source for studying high-energy interactions. The first part of Bibha’s work involved understanding the nature and composition of the cosmic rays, which nowadays we know are very energetic particles, composed mainly (99%) of protons and helium nuclei. To investigate the effect of the atmosphere on the flux of these particles, Bibha and Bose rode mules together high into the Himalayas to visit stations for their studies — a potentially scandalous act for unmarried Bibha in 1930s India. They set up their experiment at three different altitudes, reaching 4300m! The idea was to expose “halftoned” photographic plates to the cosmic rays for long periods at these altitudes and observe the particle tracks left behind.  The painstaking analysis of these photographic plates hinted at the presence of a hitherto unknown particle, which they believed to be the “mesotron.” They reported their results in four rapid publications in the prestigious journal Nature, and even tried to estimate the mass of this particle. The value of the mass was underestimated, but they were actually quick to caution that their set-up was not sensitive enough to provide accurate measurements and advocated the need for further experiments. + +Unfortunately, the outbreak of World War II in Europe in 1939 led to an embargo in obtaining photographic plates from England, and their research had to be discontinued. In post-war England, Cecil Powell and his group continued these studies using improved photographic plates in balloon and high-aircraft experiments, leading to the detection of a new particle called the “pion,” winning him the Nobel Prize in 1950. Despite Powell’s strong acknowledgement of the work of Bose and Chowdhuri, including in his book “The Study of Elementary Particles by the Photographic Method,” the latter duo was pushed into obscurity. + +Not one to give up, Bibha continued her research by joining the lab of Sir. P.M.S. Blackett in Manchester, UK for her PhD in 1945. At that time, Blackett and his collaborators were studying certain highly energetic components of cosmic rays called “penetrating showers.” Bibha undertook the study of these showers and calculated their density using innovative experimental techniques combining the Wilson cloud chamber and Geiger-Muller counters. Her thesis titled “Extensive Air Showers associated with Penetrating Particles” was submitted in 1949. This was a few months after Blackett had won the Nobel prize “for his development of the Wilson cloud chamber method, and his discoveries therewith in the fields of nuclear physics and cosmic radiation.” It is unclear how much of her work contributed to his award. What is at least known is that her thesis examiners, Janossy and Wilson himself, were impressed enough to recommend her to Dr. Homi Bhabha for a position at the prestigious Tata Institute of Fundamental Research in Mumbai (TIFR), India. At TIFR, she became the first female faculty member, and was placed in-charge of the Cloud Chamber Group where she continued her investigations on cosmic air showers. + +Bibha left TIFR in 1954 and spent a few years at the Ecole Polytechnique in Paris, teaching Physics in French and working with multi-plated cloud chambers in the French Alps. Thereafter, she moved to the U.S., first to the University of Michigan, and then to MIT, collaborating with Prof. Bruno Rossi on prototyping Plastic Scintillators for detecting large air showers. + +Upon her return to India, she joined the Physical Research Laboratory (PRL) in Ahmedabad and worked towards setting up the Kolar Gold Field Experiment, which led to the first detection of atmospheric neutrinos. She had plans of setting up further experiments for cosmic ray research in India with Dr. Vikram Sarabhai, the father of the Indian space program. However, these plans had to be abandoned due to the sudden and untimely death of Sarabhai in 1971. Soon after, she left PRL and returned to her birth city, Kolkata, where she was to spend the rest of her days. She remained active in science till her death in 1991. + +Despite her pioneering contributions in the field of cosmic ray research, Bibha received no recognition in India. Only recently, almost three decades after her death, her biography “*Bibha Chowdhuri, eine indische Hochenergiephysikerin als “Star” am Himmel*” (“A Jewel Unearthed: Bibha Chowdhuri” in English) got published by a German press.

Some of the most fascinating mysteries in 21st century physics, those about the origin and the composition of the cosmic rays, and about the nature of the dark matter, are coming from the very same human trait of curiosity: to find out what all the objects in the Universe consist of. + +And while today we are still working on the answers to the questions about the dark and energetic Cosmos, eagerly awaiting more powerful observatories like the CTAO, for the stars themselves the answer has been found. It was given by one of the most brilliant astronomers of the 20th century, Cecilia Payne-Gaposchkin, who in the process of finding the solution to this, and other scientific mysteries, had to prevail against an environment that was heavily discriminating against women, and who, in defeating prejudice and gender discrimination, became a role model and beacon for young scientists to follow in her footsteps. + +An excellent student from early on, Cecilia Payne was awarded in 1919 a scholarship to study at the prestigious Cambridge University. Pursuing physics and chemistry there, her interest in astronomy was kindled among others by Arthur Eddington. Despite being a very good student, Payne was not awarded a formal degree, as for women this would still be impossible for nearly two decades at Cambridge University at that time. Already then, however, there were a few programs in the world to foster the careers of female scientists. One such program had been initiated at Harvard College Observatory, and Cecilia Payne in 1923 became the second scientist that came to Harvard on the fellowship awarded by this program. As time would tell, she was to make some of the greatest astronomical discoveries of the 20th century at Harvard, while at the same time the fellowship would still not grant her equal treatment with her male colleagues. This is a lesson that we as a community could have learned countless times: support for careers is instrumental, but what really needs to change are our attitudes. + +Payne’s primary research interest at that time was in the atmospheres of stars and their chemical composition. Scientists had for long identified distinct absorption lines in the spectra of the Sun and other stars. Lines, that to a chemist or physicist are what the lines of a fingerprint are to a criminologist: giveaways that enable a unique identification, in our case of the very elements the stars are made of. The prevailing paradigm at that time was one that may come intuitively: that the composition of the stars, and by extension most matter in the Universe, should be very similar to the abundances observed here on Earth, the only place we can study in great detail. In other words, that the stars should predominantly be made of elements like silicon, oxygen, iron, calcium and sodium. And indeed, those ideas seemingly had one strong argument in their favor: for example, looking at the spectra of many bright stars, the lines of silicon seem to be present in about the strength one would naively expect from their abundance on Earth. Many scientists at that time, including the adviser of Payne during her PhD thesis, Henry Norris Russell (by Hertzsprung-Russell-Diagram fame) thought the case settled. Not so Payne, who by scientific curiosity and intellectual brilliance was able to see beyond the obvious. Using then-new ideas about the ionized states of matter, in her PhD thesis she was able to show without any scientific doubt that the strengths of the absorption lines betrayed much more about the states of ionization of the atoms, than about their relative abundance. Taking this into account, the spectra told a different story: the vast majority of the mass of our Sun, and nearly all stars, consists of elements that are much less abundant Earth’s crust: Hydrogen and Helium. The Earth, in a way, had again been intellectually moved from the center of the Cosmos: neither did the Sun orbit the Earth, nor were the stars even made of the same stuff we are! + +Sadly, Payne was initially declined the accolade and admiration of colleagues that should be expected to come with such a monumental discovery, one that should secure her a place in history at the sides of Copernicus, Kepler and Einstein. Russell, not able to overcome long held beliefs, lobbied Payne into a form of scientific self-denial, by noting in her thesis that although her calculations yielded the very results she showed, they seemed to be in contradiction with the obvious. Only towards the end of the 1920s it became more and more acknowledged where the real contradiction was: by those well-established men believing in their worldview above the facts uncovered by a young and brilliant colleague. And despite this and several more seminal contributions by Payne-Gaposchkin to astronomy, it would take until 1945 for the courses she taught at Harvard to become part of the official course catalogue, and until 1956 for her to become the first female full professor at Harvard. + +So, while every day on which we study the composition of the Universe and all the extreme objects it contains we are remembered that all of us are standing on the shoulders of scientific giants like Payne-Gaposchkin, at the same time we must remember the hardships she and others had, and sadly still have, to endure by not being given the equal respect and standing among colleagues that should come with excellent scientific work. Changing the attitudes of humans seems to be at least as difficult as understanding the composition of the Universe. + +———- + +Recommended reading by the author: + +– “What Stars Are Made of: The Life of Cecilia Payne-Gaposchkin” by D.

Student in Physics at the University of Trieste and student of the Collegio Universitario Luciano Fonda (Italy).* + +Imagine being a Chinese woman born in 1912, at the very beginning of the Xinhai Revolution. Imagine being highly interested in poetry and science but not being allowed to attend any school. This is the context in which Chien-Shiung Wu, the “Queen of Nuclear Research,” was born. + +In a dark time for women’s emancipation, Wu was lucky because she lived in a rare spot of light: her mother was a teacher, her father was an engineer and they both strongly believed in gender equality. In particular, her father founded one of the first schools for girls in Jiangsu and he encouraged girls, including his daughter, to join. At the age of 10, Wu had to move to Shangai to continue her studies. In 1929, she was admitted to the Central National University, where she graduated in Physics with the highest honors in 1934. + +In 1936, thanks to the economic support of her uncle, Wu moved to the United States after the University of Michigan offered her a scholarship to earn a PhD. Nevertheless, she became attracted to the facilities at Berkley, which hosted the first cyclotron. Thus, she enrolled at the University of Berkley as soon as Professor Lawrence, amazed by her talent, offered her another scholarship for a PhD in Nuclear Physics. She obtained the PhD in Physics in 1940. + +In 1942, Chien-Shiung Wu married Luke Yuan, Professor Lawrence’s student, and moved to Princeton. There, she had to face the America of that time, where women were not allowed to teach in most universities. Again, Professor Lawrence played a fundamental role in Wu’s life: he recommended her to many prestigious universities and, in the end, she became first woman hired as a faculty member by Princeton’s physics department. + +During the years that followed, Wu collaborated with prominent and established scientists such as Robert Oppenheimer and Emilio Segrè. The latter made possible a meeting between Wu and Enrico Fermi, who asked her to participate in the Manhattan Project at Columbia University, focused on the process of uranium enrichment. In 1944, she joined the Columbia University in New York City. + +It was at the Columbia University where Wu would carry out what would later be one of her greatest legacies: the Wu Experiment. In 1956, and after a review of some experimental observations regarding new particles, the theoretical physicists Tsung-Dao Lee and Chen Ning Yang proposed that, despite what happened with the other fundamental forces in Physics, the conservation of the so-called “parity” was violated in the weak interactions, responsible for the radioactive decay in subatomic particles (this force plays a fundamental role in the nuclear fusion that takes place, for example, inside stars). In order to demonstrate the theory, it was necessary to execute a challenging experiment. Professor Lawrence, who once described Wu as the most talented female experimental physicist he had ever known stated, “She would make any laboratory shine!” This reputation is why the two scientists asked Professor Wu to deal with the experiment. Parity implies that the properties of a system in a frame of reference keep unchanged in the frame of reference mirrored with respect to an axis. Wu’s experiment spun radioactive cobalt-60 nuclei at temperatures close to absolute zero (-273.15 ℃), aligned within a uniform magnetic field. In doing so, the cobalt is transformed into another element through the emission of an electron, process known as beta decay. If parity was preserved, the electrons would shoot off in a certain direction. If, on the contrary, the electrons did not follow the predicted direction, parity would not be conserved. The experiment proved that they did not, therefore the violation of parity was demonstrated for weak interactions. + +It was a revolutionary result for Nuclear Physics. In 1957, Lee and Yang received the Nobel Prize for *“their penetrating investigation of the so-called parity laws which has led to important discoveries regarding the elementary particles,”* while Chien-Shiung Wu was overlooked by the prize committee. Nonetheless, in 1978, she won the first Wolf Prize in Physics *“for her persistent and successful exploration of the weak interaction which helped establish the precise form and the non-conservation of parity for this new natural force.”*  The Wolf Prize is considered one of the most prestigious awards in various fields, including Physics, in which only two of the 68 laureates since 1978 have been women. + +She retired in 1981 and became a professor emerita at the Columbia University. After that, she travelled around the world to talk about how dedication and determination allowed her to become part of something that is still a highly gendered field. In this way, she became an inspirational figure for girls and women all around the globe. + +Wu teaches us that in STEM, as well as in every field, we always have to be ourselves, to show ourselves as we excel and to fight for our rights so that our capacities and the value of our work are the only parameters on which we can be judged. + +Wu suffered a stroke on 16 February 1997, in New York City.

It was only after experiencing discrimination in his pursuit to explore the Universe, that he ended up becoming one of the most committed LGBTQIA+ rights movement activists of the past century. + +In fact, after World War II, he followed his passion for the stars and space and, under the supervision of the eminent astronomer and physicist [Cecilia Payne-Gaposchkin](https://www.cta-observatory.org/building-from-diversity-article-cecilia-payne-gaposchkin/), earned a PhD in Astronomy at Harvard University. His thesis was based on the observation and photoelectric measurements of RV Tau stars and yellow semiregular variables from 1952 to 1954. He then started teaching at Georgetown University and later became an astronomer at the U.S. Army Map Service in 1957. + +However, despite his excellent education and work, Frank Kameny was fired after a few months from the Army, when they discovered that he had previously been arrested because of his homosexuality or what they called “lewd conduct.” Unfortunately, in that period, he was one of many people fired due to discriminatory policies against homosexuality followed at the time. + +After losing his appeal, he was barred from applying for any other federal employment for three years. This was quite the paradox considering his education and profession were in high demand at the time in the “race to space.” But it was this rejection that ignited his passion for what became his life-long commitment to fighting injustice. + +Between 1958 and 1959, while he struggled to work in academia and private industry under difficult financial conditions as money was barely sufficient for food, he discovered the Mattachine Society, a secret organization that advocated for homosexual rights. In 1965, he helped the Society organize a protest in front of the White House, the first to be organized by a homosexual organization in Washington DC. Together with the Mattachine Society, Kameny also planned the first Pride Parade in New York in 1970. + +In the same years, he supported many employees that were fired only because of their sexuality and acted as a first point of contact to mediate with lawyers. Moreover, he used his name to write letters condemning homophobic behaviours – a brave and strong message in times when very few dared to disclose their sexual orientation. + +And in 1973, Kameny joined forces with Barbara Gittings, leader of LGBTQIA+ rights movement, to take his activism even further by successfully challenging the American Psychiatric Association to remove homosexuality from the list of mental disorders. + +Kameny’s story is an inspiration to many for a variety of reasons the first being for his courage, teaching us that no-one should give up their true self and should fight for the right to be themselves, even if they often stand alone against many more formidable opponents. He also teaches us commitment, integrity and perseverance by bringing his determination and skill to his fight for equality. Finally, Kameny teaches us that one voice can be powerful but many are a force for change – his collaboration with many other activists to create a network to raise awareness about sexual orientation and diversity helped create a foundation for activism and change that we continue to build upon today. + +Thus, Kameny’s legacy, which started in Astronomy and led to him becoming one of the most significant figures in the LGBTQIA+ movement, was and still is fundamental to achieve an inclusive society and scientific field. Nowadays, there is still a lot of work to do in STEM (Science, Technology, Engineering and Mathematics): A recent study (Cech and Waidzunas, 2021) on LGBTQIA+ workers in STEM workplaces reports that they are more likely to experience episodes of harassment and social marginalization. Moreover, the loss of career opportunities and devaluation of their work are also common experiences. As a consequence, many LGBTQIA+ professionals (22%) have thought to leave the STEM field, thus leading to a loss of knowledge, experience and technological innovation in the scientific area. Therefore, it is key to continue making inclusion one of the core rights of all working environments. + +The end of Kameny’s scientific career was a loss for science but a win for LGBTQIA+ rights. But how many other marginalized people and their potential contributions to science have been lost, as well?  Thanks to Frank Kameny and all the activists from our past, present and future, there is a path forward for equal rights for all in society and science. + +— + +Bibliography: + +[Frank Kameny’s Orderly, Square Gay-Rights Activism | The New Yorker](https://www.newyorker.com/magazine/2020/06/29/frank-kamenys-orderly-square-gay-rights-activism) + +[Frank Kameny: Astronomer and Gay Rights Pioneer | Capitol Technology University (captechu.edu)](https://www.captechu.edu/blog/frank-kameny-astronomer-and-gay-rights-pioneer) + +[Astronomer Frank Kameny: Founding Father of the Gay Rights Movement (wondriumdaily.com)](https://www.wondriumdaily.com/astronomer-frank-kameny-founding-father-of-the-gay-rights-movement/) + +[The Mattachine Society – LGBTQIA+ Studies: A Resource Guide – Research Guides at Library of Congress (loc.gov)](https://guides.loc.gov/lgbtq-studies/before-stonewall/mattachine) + +[About  |  Lesbian, Gay, Bisexual, Transgender and Queer Pride Month  |  Library of Congress (loc.gov)](https://www.loc.gov/lgbt-pride-month/about/) + +[Frank Kameny | Making Gay History](https://makinggayhistory.com/podcast/episode-1-5/) + +[The A.P.A.

It is a sequence of different measurement methods, relying on various physics phenomena. The most interesting aspect is that every method works only in a specific range of distance, and this is why we need a sequence of several steps (exactly as in a ladder) to reach very faraway objects. Fortunately, every step overlaps with both the previous and the next one, so it is possible to obtain a resulting ladder which is well calibrated. Today, this approach allows us to measure the huge distances in the Universe, which is an issue that has challenged astronomers of all epochs. Several scientists gave their contribution in the realization of the “distance ladder.” In particular, a crucial result was achieved in 1908 by a brilliant woman astronomer: Henrietta Swan Leavitt. As we will learn through her story, her findings helped solve the fundamental problem of measuring the distance between distant objects in space. Similarly, the story of her life is still probably helping us today in solving the embarrassing problem of the cultural distance between the role of men and women in science. + +At the beginning of the 20th century, astronomers were still wondering if some of the cosmic objects they observed, which at that time looked like “nebulae,” were part of the Milky Way or if, on the contrary, they were extragalactic sources. This so-called “Great Debate” [2] relied on the  incapability to measure their distance. The only methods available for measuring distances at that moment were based on triangulation and parallax, but those objects were too far for these approaches to work (nowadays, we know they were galaxies, whose distances are actually hundreds of times larger than the size of the Milky Way). + +In general, when we look at an astronomical object, we record a light intensity (the *magnitude*) which is affected by the distance of the source. If we knew the intrinsic light emission (the *luminosity*), then we could calculate the distance of the source with just one equation, but the problem is that usually it is impossible to have such information in advance. The only chance is to discover a “standard candle,” a class of cosmic source characterized by having the same intrinsic luminosity. In this scenario, the magnitude of such an object can be used to calculate its distance using the laws of light propagation, because we already know its intrinsic luminosity. This intriguing possibility became feasible in 1908, when the first standard candle of astronomy was unexpectedly discovered, thanks to the intuition and the hard work of Leavitt, an insightful and tenacious woman. + +Between 1877 and 1919, the director of the Harvard College Observatory was Edward Charles Pickering. He was a famous member of the Royal Astronomical Society and he decided to focus his research on the study of stellar photometry and spectroscopy, two disciplines based on the analysis of light intensity and frequency components, respectively. At that time, the analysis of astronomical sources was carried out using *photographic plates*, whose examination required a lot of time and experience. Moreover, excellent math skills were fundamental to work in astronomy, as there were no electronic devices to make calculations. For this reason, Pickering chose to recruit over 80 women to work for him, a group that later would be known as the “Harvard Computers.” In the team there was a young woman graduated in the Radcliffe College, Henrietta Swan Leavitt. She was tasked with examining a huge amount of data concerning the brightness of variable stars, objects whose emission presents a periodic variation in time (known as *period*). In particular, she focused on the “Cepheid variables,” a class of periodic objects presenting the same features of the star Delta Cephei. In 1908, she published her results about almost 2000 variable stars, noting a new unexpected relationship: The brighter the star,  the longer its period [3]. In the following years, she looked more carefully at this curious relation, focusing on 25 Cepheids belonging to the Small Magellanic Cloud, a dwarf galaxy near the Milky Way. As they were approximately at the same distance, their differences in magnitude (the observed brightness) had to correspond to real differences in intrinsic luminosity. Henrietta analyzed her data sample considering this situation and found out a very surprising relation: the logarithm of the period is proportional to the logarithm of average luminosity. This typical feature of Cepheids constitutes a very powerful relation for astronomers! Following Henrietta’s prescriptions, one can calculate the intrinsic luminosity of a Cepheid and hence its distance, simply by measuring the period of its magnitude variation. This discovery constituted a giant leap in the realization of the “distance ladder” for measuring the position of remote astronomical objects. + +The period-luminosity relationship for Cepheids discovered by Henrietta was published in 1912 in a paper by Pickering [4], although the first sentence indicated that it was “prepared by Miss Leavitt.” This relation allowed to develop the modern understanding of cosmological distances and the Universe structure, being an effective method to accurately measure distances on an inter-galactic scale. In particular, when Cepheids were identified in the Andromeda Constellation [5] the “Leavitt law” allowed to definitely affirm that those “nebulae” were not part of the Milky Way, but galaxies themselves. The Harvard College Observatory became a premiere observatory in the world and several scientists said that Leavitt deserved the Nobel Prize for her groundbreaking research. Unfortunately, she died very young in 1921, at the age of 53. Her death was seen as a tragedy by other astronomers, not only for her scientific skills, but also because “she had the happy, joyful, faculty of appreciating all that was worthy and lovable in others, and was possessed of a nature so full of sunshine that, to her, all of life became beautiful and full of meaning” [6]. + +———- + +[1] Webb, Stephen (1999). [*Measuring the Universe: The Cosmological Distance Ladder*](https://books.google.com/books?id=ntZwxttZF-sC).

The story of how, as a graduate student at the University of Cambridge, she detected “a bit of scruff” on the chart recorder of the radio telescope designed by her supervisor Anthony Hewish. A telescope that she’d built in 1967 as part of her PhD – the Interplanetary Scintillation Array at the Mullard Radio Astronomy Observatory in Cambridge. + +The bit of scruff turned out to be what is now known as pulsar PSR B1919+21, the rapidly rotating neutron star that is the collapsed core of a massive star, just a few kilometres across and spinning with a period of 1.3 seconds. The jet of radiation from this neutron star was what was being measured as the pulsing radio signal. Of course, at the time this was a completely new phenomenon. Subsequently, the consequences for astrophysics were profound. However, right then, even proving that the signal seen on the chart recorder was coming from a cosmic source and was not interference was challenge enough. Trawling through many metres of paper from the chart recorder, Jocelyn was looking for faint signals on a noisy background that repeated at the sidereal rate (i.e., 23hr 56m), rather than the solar rate (i.e., 24 hrs). Once the team were convinced that the source was indeed cosmic, and not terrestrial in origin, they then jokingly dubbed it LGM (little green men, later LGM-1 as a second was found), so unexpected and unusual it was, seemingly more akin to an artificial signal that a natural one. + +This story is well known, many articles, discussions, even TV programmes, have been devoted to it. Not so well known is the story of how Jocelyn learnt where on the sky her remarkable new object lies. As a radio astronomer, working through the day (as well as the night!) the stars are not visible to the eye. How does one recognise the constellation (Vulpecula – the little fox) that the source is found in? Jocelyn wanted to know. + +Here Jocelyn’s origins from Northern Ireland come in. She lived in Lurgan in County Armagh. Her father, Philip Bell, was the architect for Armagh Observatory, one of the world’s oldest optical observatories, one that has been in continuous use since its foundation in 1790. Architect here was an official government position with responsibilities for looking after the observatory building, not actually designing it. Jocelyn had grown up experiencing Armagh Observatory from the inside, including following her father around the ducts under the roofing when he was fixing leaks and making repairs! + +In the mid-60’s the Armagh Observatory Director, Eric Lindsay, had, following a 2-decade campaign, managed to raise the funds to add a Planetarium to the Observatory, to meet the growing demand for public outreach alongside its scientific mission. Joceyln’s father then became the architect for the Planetarium as well, responsible for designing its innovative, striking dome.  In turn, the Dome became an iconic symbol of the space age in Armagh for this was also the era of the Apollo Moon programme and featured strongly in the Planetarium’s public programmes. + +PSR B1919+21 was discovered on 28 November 1967. The next month Jocelyn was back home in Armagh, and with her family, for Christmas. The Planetarium had just been completed. The roof was in place and, protected from leaks, the first projector (a GOTO Mars projector from Japan) freshly installed under the guidance of the Planetarium’s first Director, Patrick Moore (who later became an icon himself as the presenter of the BBC’s Sky at Night).  Jocelyn, of course, wanted to see the new Planetarium, even though it had not yet opened to the public. She also wanted to know the location of her LGM on the sky. + +Vulpecula is in fact neatly sited in the middle of the Summer Triangle – the asterism made up by the three bright stars of Altair, Deneb and Vega. So, while it is a rather modest constellation with no stars in it that are brighter than 4th magnitude, Vulpecula can be readily located in the sky using the Summer Triangle as a guide. So, Patrick Moore was well able to show Jocelyn where the constellation lay. However, the reason why Jocelyn was so interested in Vulpecula had to remain a mystery, for she could not then tell the story of the LGM.  It remained a secret, only known to the research team! + +The reason for this is, of course, now history, for it was the location of the first known pulsar! Half-a-century later, when the Armagh Planetarium was celebrating its 50th anniversary, we were honoured by Jocelyn visiting us and telling the story of her own first there and of finding where Vulpecula is on the Dome. We even recorded a short planetarium show where she narrates this story and we show you Vulpecula in the Summer Triangle using our very latest Digistar projector, now in the age of the digital planetarium and the immersive experience it provides! diff --git a/src/content/news/building-from-diversity-article-margherita-hack.md b/src/content/news/building-from-diversity-article-margherita-hack.md new file mode 100644 index 0000000..205f85a --- /dev/null +++ b/src/content/news/building-from-diversity-article-margherita-hack.md @@ -0,0 +1,59 @@ +--- +title: "Margherita Hack: Astronomer and Changemaker, now has her own Statue" +description: "In the fifth article of the CTAO’s “Building from Diversity” series, Anna Wolter, in collaboration with Claudia Mignone (INAF), delves into the personality and social impact of the astronomer Margherita Hack, of whom the first statue of a…" +date: 2022-06-30 +category: news +author: CTAO +cover: /uploads/Poster_ilustracion_facebook_MH-01-1-1600x840.png +draft: false +--- + +This article is part of the “[Building from Diversity](https://www.ctao.org/news-resources/outreach-and-education/astrodiversity/building-from-diversity/)” project. *Written by Anna Wolter with the collaboration of Claudia Mignone (INAF)* + +Smiling, attentive, inclusive, caustic. + +Able to explain complex ideas using a simple language. Widely known and easily recognizable by many. Lover of animals and bicycles. Driven by the desire to always go a step further, by the curiosity to understand and explain something that is still a mystery. Always ready to get involved and to do it with her own hands. Aware of our place in the Universe: a small, inhabited grain of sand. + +This, and much more, was Margherita Hack, or Marga to her husband and close friends. She was born in Florence in 1922, where she studied in the 1940s, during the Second World War, with a thesis in observational astronomy. She worked a few years at the Brera Observatory of Milan where she did not find the equipment and support she would have liked. Finally, in 1964, she won the chair of Astrophysics at the University of Trieste, which brought as a “gift” the position of Director of the Astronomical Observatory. Lo and behold: Margherita Hack became the first woman in Italy to run an Astronomical Observatory! A milestone for women in science. Under her leadership, the observatory would turn from a small, provincial institute to a lively and active international research center. + +It is difficult then to know which of her characteristics captured more the imagination of the Deloitte Foundation when they selected her as the “role model” – a female scientist for whom they would erect a statue, the first in Italy, where statues of women already exist but as goddesses and madonnas, representations of ideals or abstract concepts. I was honoured to be involved in [the selection process](https://www2.deloitte.com/it/it/pages/about-deloitte/articles/una-scultura-per-margherita-hack-a-milano---deloitte.html), in a diverse panel of artists, municipality managers, scientists and various intellectual figures. Sissi, the winning artist, inspired her design in the long periods spent listening to Margherita’s voice,  becoming identified with her,  understanding her essence. And finally, on June 13, her work was unveiled, which the city of Milan has destined to the gardens facing the Università Statale. The statue will be seen by thousands of students passing by as they seek their own path in life, every day. + +We will ask ourselves, in the years to come, how effective this statue of Margherita has been as a reference and as a role model for girls and boys. As we reflect on why her figure  is so representative, we are aware that Margherita Hack did not make any particular scientific discoveries, even if her work is highly respectable, like that of many colleagues. However, she achieved her results and made an impact by keeping an open eye towards the world and innovation. For example, she did not have an easy life at the Brera Observatory, because she did not appreciate the study of classical astronomy, then carried out by her colleagues with the Merate telescopes. However, through collaborations – mostly international ones, from France to Holland and then again in the United States, from Berkeley to Princeton – she learnt and developed the study of spectroscopy as a tool to investigate the physical state of celestial sources. In the 1970s and 1980s, she took advantage of the IUE mission (a satellite for observation in the ultraviolet band) to revamp the Trieste Observatory, involving it in international research and pushing it towards one of the most cutting-edge disciplines of contemporary astrophysics: space science. She was a real manager. She knew how to unite the people working in the institute and to push them in their career, fostering their independence. + +Always active in the communication of science to the general public, from print media to books and later television, she became even more active in outreach after her retirement, from the direction of the Observatory in 1987 and then, ten years later, from the Department of Physics and Astronomy of the University of Trieste. In her relationship with the public, she showed an uncommon capacity for inclusion and openness. She was always attentive to the rights of all, fighting battles for civil and minorities rights. + +I think that much of her attention to others, and also the ability to not fall victim to stereotypes, comes from her family atmosphere and environment. She came from a non-traditional family in which, for political reasons (during intense fascist times), had a father that did not work, but lives peacefully the fact that it is the wife who provides for the sustenance of the family. Therefore, she had a caring father, but also the influence of broad cultural views and a proponent of freedom. They were also a vegetarian family out of respect for animals. In short, I suspect that Margherita didn’t even experience stereotypes in her childhood, and this made it, perhaps, an easier task for her to care for all. + +Today, I wonder if the one represented in the statue is the right gesture to remember the work of an astrophysicist who has always looked at the essence of things (spectroscopy, in fact, to put it in scientific terms) and not at the appearance or classification (the “classical” astronomer who measures the positions of stars in the sky). I urge our scientific community to devise in the next few years a new gesture that represents the work we do here, today, with large telescopes and observatories such as CTAO. A gesture that is able to simultaneously grasp the charm of the knowledge of refined detail and the complexity of the framework in which it is inserted.   * * + +Certainly, I would like to emphasize that Margherita Hack was not a “genius” in the sense of being so out of the ordinary as to be unattainable, inimitable. Margherita is each and every one of us, with her bad temper, when needed, with her smiles, all the more often, with the desire and tenacity to get, with the curiosity to find her own way, the desire to make things with her own hands. May the Universe continue to teach us new facts. She is a symbol, a model, an “undisputed myth,” a recognizable and accessible figure. And don’t forget: “Heaven has always been an open book,” as the commemorative plaque says.

Did she ever imagined that, some years later, in 1963, she would be the first woman to become a full professor at Padua University, one of the oldest Universities in the world? + +In her vigorous career, Milla’s research was devoted to subnuclear physics, the study of particles smaller than the atomic nucleus. Milla was particularly concerned with the weak force, one of the four fundamental interactions together with gravitational, electromagnetic and strong forces. In those fervent post-war years, theories, models, brilliant intuitions and amazing discoveries followed each other, and innovative experiments were devised and designed all over the world. These years were lived with great enthusiasm, but with very few means available. Italian physicists had the vital need to continue the legacy of Bruno Rossi, one of the fathers of cosmic-ray studies who had been ignominiously forced to leave Padua due to racial laws in 1938. + +To search for new subatomic particles, a cheap and clever method was to send instruments on balloons at high altitudes and study the interaction of the atmosphere with energetic particles of extraterrestrial origin, cosmic rays. This was also the method adopted by Milla in her first years of research, when she stood out for her determination, patience and analytical skills – important qualities needed to identify and characterize the numerous traces left by cosmic ray particles on nuclear emulsion plates. She was fragile and delicate in appearance, but, during her active and prolific life, she showed great determination, tenacity, energy and strength of character, qualities that certainly helped her in her career. She was also a brilliant and unconventional experimentalist, always trying to think “out of the box.” With this spirit, when one of the first synchrotron accelerators became available in the late 1950s, Milla had the idea of exposing nuclear emulsion plates to a pion beam. One of the most important results of her career came soon after: the discovery of the “strange” particle antilambda. + +Milla was an avid traveller, too. In the early 1960s, she participated in several experiments aimed at investigating the properties of the weak force in Argonne, CERN and Moscow. In the mid 1960s Milla started to focus her attention on another weakly interacting particle: the neutrino. Neutrinos are elusive subatomic particles that were theoretically proposed in 1930 by Wolfgang Pauli but experimentally detected only in 1956. Her studies on neutrinos brought her enthusiasm and vitality to the main European facilities: in Aachen, Germany, at CERN and the Gran Sasso laboratory in Italy. By then, Milla’s authority and competence was internationally known and led her to lead the Padua section of the Istituto Nazionale di Fisica Nucleare (INFN) from 1965 to 1968 and the Physics Department from 1973 to 1978. + +Art lover and mountain enthusiast, Milla was also involved in social battles that have marked the history of Italy’s post-war period, especially in the defense of democracy and the emancipation of women. She was proud of the golden mimosa she had received as recognition from the Union of Women in Italy, an association for political, social, and cultural promotion. Since 1946, the golden mimosa flower has been traditionally given to women on Women’s Day (8 March) in Italy. The tree has a beautiful golden bloom that, despite its delicate appearance, can grow in the most difficult conditions – a fitting representation for women like Milla! + +Today Milla’s legacy lives on in the prominent Neutrino Telescope conference. Inaugurated in 1988, this biennial conference in Venice has become the fixed appointment for hundreds of physicists who meet in the splendid setting of the Italian city of art to discuss the most recent findings related to neutrino physics and astrophysics. + +— + +Bibliography: + +“Milla Baldo Ceolin”, Maria Nicolaci, Ed.

Very early on she was delighted by observing the stars in the night sky. Starting when she was nine, she grew and became an adolescent embedded in the Yugoslav wars and their consequences. She said that “when you grow up in chaos, with so many unanswered questions, you feel so constricted, so locked in, that reading books, walking in nature and looking up at the night sky is a way to escape so much madness.” + +Thus, Mirjana decided to study Astrophysics, expecting to understand the processes behind the beauty of the night skies. With the encouragement of her family, and the required grants, she earned her PhD in extragalactic astrophysics at the Instituto de Astrofísica de Canarias (IAC) in Spain. And this is where her childhood passion for Africa bloomed – amazed by its beauty and diversity but disturbed by the inequalities. Her desire to help, led her to Tanzania to teach in the slums, and to instil in the children that education can change their lives.  After her thesis, she spent a year as a postdoc in South Africa, at the University of Durban. She came to Granada (Spain) for a meeting about Active Galactic Nuclei (AGN), and she was offered a postdoc at the Instituto de Astrofísica de Andalucía (IAA), where she spent six years. She never stopped her involvement with the various projects already started in Africa, spending her holidays there to do volunteer work with children. + +During her many humanitarian trips, she also made contacts with young African astrophysicists trying to develop the discipline in their own countries, like Rwanda and Ethiopia. Finally, she decided to move to Addis Ababa (Ethiopia) in 2016 as a researcher in the Ethiopian Space Science and Technology Institute. Recruited for her experience in the field and knowledge of Africa, she is the only woman and the only European on the team. Since 2016, she has been working hard to develop the space sector in Ethiopia, sometimes under very difficult conditions, including the ongoing civil war in the region of Tigray, northern Ethiopia. + +Despite the challenges, she has made an enormous impact on the academic and societal conditions in Ethiopia and throughout the continent through her contributions to the organisation of the institute; the country’s science sector strategy for the next 20 years; the generation of skills in astronomy and space science, technology and research; the popularisation of astronomy among the general public; and the inclusion of women and girls in science. Mirjana organised an IAU symposium on AGN for the first time in Addis Ababa in October 2019, the third IAU symposium held in Africa. She also has supervised more than 20 master and PhD students. Among other responsibilities, she serves currently as a secretary of the IAU Division C on Education, Outreach and Heritage. In 2019, she promoted the “STEM for GIRLS in Ethiopia” initiative, with the aim to inspire more girls to do science, technology, engineering and mathematics. In collaboration with the African Astronomical Society, she co-founded the African Network of Women in Astronomy, and has been its main coordinator since its establishment in 2020. + +Among the various awards Mirjana has received for such an amazing and impressive body of work, there are two that stand out for their international scope: The first, awarded in 2018, was the “Nature Research’s Inspiring Science Award” for which she impressed judges with her capacity to excel in her own research, as well as with the depth and breadth of her efforts in Africa to encourage women and girls in science. The second was the Inaugural 2021 Jocelyn Bell Burnell Inspiration Medal from the European Astronomical Society, awarded to Mirjana for her work in developing astronomy, science and education as a route out of poverty and to improve the quality of life for young people in Africa.

I love to talk about it. I am proud of myself because I am currently an astrophysicist, which is, in a sense, somehow similar. It is clear that I was totally fascinated by the sky at first, but this soon turned into a fascination with the Universe. + +I remember when I was still at school, deciding which Bachelor’s degree to pursue. I checked all the requirements to be an astronaut on the European Space Agency (ESA) and the National Air and Space Administration (NASA) webpages. Unfortunately, I came across something that could potentially destroy my dream of becoming an astronaut: myopia. Myopia is a common vision condition that can be described as blurred vision when an object moves further away from a person. The webpage states it clearly: an astronaut candidate needs to have perfect vision. Astronaut candidates must not have a history of having glasses, contact lenses, laser or eye surgery. In my eyes, this was the end of my dream. I am still wondering if something has changed, in the meanwhile…never say never! + +In January 1977, Sally Ride experienced a similar feeling while finishing her PhD in Physics, spotting an article in a newspaper advertising that NASA was recruiting a new group of astronauts for the Space Shuttle program and that – for the first time – women could apply! She knew immediately she wanted to fly into space. Ride was one of the 8,079 applications received by NASA, and despite the competition, she became the first American woman and third woman ever to go to space. + +Before we go any further, let us take a step back. Before Sally Ride decided to study Physics and become an astronaut, she was working towards a career as a tennis player. Her perfect physical shape actually helped her pass the astronaut selection process. During this period, she met Tam Elizabeth O’Shaughnessy, a tennis player and scientific writer, who was her partner in life for 27 years, until her death in 2012. Sally and Tam became growingly concerned about the lack of women in science. They understood that girls needed more role models to pursue and succeed in this field. As Sally liked to say, “You can’t be what you can’t see.” This is a quote that is still valid nowadays as it was more than 40 years ago. + +In fact, as the first American female astronaut assigned to a space shuttle crew, Sally got the attention of the media and had to deal with questions like “Do you weep when things go wrong on the job?”. She stayed calm and answered, “How come nobody ever asks Rick these questions?” Rick Hauck, her crew mate. + +In 2001, Sally and Tam founded the non-profit organisation “Sally Ride Science.” They created programs to inspire girls and boys of all backgrounds in science. Today, the “Sally Ride Science” is part of the University of California, San Diego, where Sally became a Professor in Physics after leaving NASA. The year after Sally died, Tam accepted the Presidential Medal of Freedom from President Obama on behalf of Sally, the American highest civilian honor. + +Sally Ride was, and still is, a role model in the scientific field for the generations that followed her (including mine). She was not only a pioneer in space travel, helping open that field to other women, but she was also a scientist committed to gender equity, promoting the scientific career among girls and women, and encouraging young people to stay in science as they go through their career. She is one of the leading figures on which we build the future in science. + +— + +Bibliography: diff --git a/src/content/news/building-from-diversity-article-vera-rubin.md b/src/content/news/building-from-diversity-article-vera-rubin.md new file mode 100644 index 0000000..8836c64 --- /dev/null +++ b/src/content/news/building-from-diversity-article-vera-rubin.md @@ -0,0 +1,42 @@ +--- +title: "Vera Cooper Rubin: Uncovering Dark Matter, a Missing Chunk of the Universe" +description: "In the fourth article of the CTAO’s “Building from Diversity” series, Anjana Kaushik Talluri (PhD Student at the University of Minnesota) presents the story of how Vera Rubin provided the first strong evidence of dark matter and how her…" +date: 2022-05-31 +category: news +author: CTAO +cover: /uploads/Poster_ilustracion_facebook_VR-01-1600x840.png +draft: false +--- + +This article is part of the “[Building from Diversity](https://www.ctao.org/news-resources/outreach-and-education/astrodiversity/building-from-diversity/)” project. *Written by Anjana Kaushik Talluri, PhD student at the University of Minnesota + +* + +A whopping 95% of the Universe is hidden! The visible, or baryonic, matter that we are familiar with accounts for a mere 5% of the Universe, while the rest comprises “dark matter” (27%) and “dark energy” (68%). + +While the fact that dark matter exists is supported with irrefutable evidence today, just a few decades ago, this idea was unthinkable. In 1933, astronomer Fritz Zwicky discovered a glaring discrepancy in the mass of galaxies in the Coma Cluster inferred from the light observed and the total mass calculated from the rotational velocities of the galaxies, which for obscure reasons ended up being much higher. Though Zwicky correctly attributed this difference in mass to invisible matter, there was, unfortunately, insufficient technology available to back up his claims. Decades later, Vera Rubin, a preeminent American astronomer, opened a window to the field of dark matter by presenting concrete observational evidence to the astronomy community, which eventually forced them to take the argument seriously. The story of how the life of Vera Rubin is intriguing and an inspiration for many generations to come. + +In 1963, on a clear night at the Kitt Peak Observatory in Arizona, Vera Rubin and her collaborator, Kent Ford, looked at the spectra of young, hot stars in our nearest neighbor, the Andromeda galaxy, to measure their speeds about the center of the galaxy. Having shown in her prior work that galaxies rotate about a central point, Rubin was passionate to learn more about the motion of the stars in a galaxy. Thanks to Ford’s new image tube spectrograph, there was a drastic reduction in the exposure time, and they were able to obtain multiple (4-5) spectra each night. On the first night, as Rubin alternated between developing the images that Ford observed and eating ice cream, she realized that she had stumbled upon a puzzling mystery— the rotational curves she obtained seemed to indicate that the speeds of the stars in the outer parts of the galaxy were quite high, enough to fling them out of the gravitational pull of the galaxy! And yet, these stars remained in stable orbits. In a spiral galaxy like the Andromeda, where most of the light (and therefore, the corresponding mass) is concentrated in the central regions, one would expect from Newtonian physics that objects at larger radii would have lower orbital velocities due to a reduced gravitational force, much like the planets in our solar system. However, the flat rotational curves, indicating a constant orbital speed with distance, hinted at the existence of a form of matter in the outer regions of the galaxies that was invisible. Through painstaking work, Rubin continued to measure the speeds of more than 60 galaxies, all of which also showed flat rotation curves. While it was far from a smooth ride, eventually, Rubin was successful in throwing light on the existence of dark matter. + +Rubin’s curiosity and love for the Cosmos was highly palpable right from a young age; 11-year-old Rubin loved looking at the stars from her bedroom window, and she took pride in building a telescope from scratch with the help of her father. After completing her bachelor’s degree as the only astronomy student at the all-women’s Vassar College, Rubin applied for and was denied admission at Princeton University, which was not accepting female students at the time. She instead pursued her master’s at Cornell University, where she focused on studying the large-scale velocity distribution of galaxies and later earned her PhD in Astronomy from Georgetown University. + +Throughout Rubin’s career, as was typical of the time and, sadly, to a large extent even today, gender discrimination was highly prevalent. In fact, this was apparent in Rubin’s life quite early on. Not only did her high school physics teacher ignore the girl students in the class, but when Rubin informed him of her acceptance into Vassar College, her teacher replied, “You should do OK as long as you stay away from science.” She did not let such incidents deter her, however, and was an active champion of women’s rights and gender equality. At conferences, for example, she would call ahead to make sure that women were included in the mix of keynote speakers. In 1965, a time when women were not granted access to state-of-the-art telescopes such as the Palomar, Rubin not only became the first woman to gain access to Palomar, but she also played a key role in helping women gain access to the bathrooms and living quarters at the observatory, which were otherwise reserved only for men. With abundant passion and the support of her family, Rubin overcame every obstacle and kept pushing the boundaries of the male-dominated academia. + +Rubin’s work was the cornerstone of dark matter research. Her findings revealed a large missing chunk of the Universe and opened up a new field for the following generations of astronomers to explore. Her unparalleled contributions to this field should have truly won her a Nobel prize! + +With the aid of cutting-edge telescopes, we know today that dark matter does not emit or absorb light, which makes it invisible to conventional detectors. It is present in large halos around galaxies and binds luminous matter together in gravitationally bound structures. Dark matter is most likely made of non-baryonic, exotic particles such as Weakly Interacting Massive Particles (WIMPs) which still require detection. Powerful, next-generation observatories with superior sensitivities such as the CTAO will be instrumental in helping us understand the true nature and distribution of dark matter in the Universe. + +A much respected and beloved mentor, Rubin was heavily involved in ensuring her students received credit for their work. In fact, in her biography, she recalls a time when she refused to get her paper published when she was informed that her students’ names would not be included in it. Always caring for and willing to lend a helping hand to others, Vera Rubin will forever be remembered as a kind person and an inspiring mentor. + +Rubin always said, “Don’t let anyone keep you down for silly reasons such as who you are, and don’t worry about prizes and fame. The real prize is finding something new out there.” + +And she was a living embodiment of her advice. + +———- + +1. Rubin, V. C. (n.d.).*AA49-Frontmatter Ari 9 August 2011 16:7 – annualreviews.org*.

She grew up in Campinas, Brazil, and was just 15 years old when her curiosity for physics was piqued. Inspired by a teacher who presented her with the challenging task of teaching her classmates who had failed final exams, Carola’s fascination with physics and teaching grew. During her school vacations, she dedicated her time to providing physics tutoring to her classmates, a venture that not only satisfied her love for the subject but also helped her earn some extra money. + +In considering her professional choices, she says “When you’re 15, you have no idea what you will do. You don’t have the imagination to know what a physicist does, mainly because in high school the teaching of physics is very basic. The opportunities I had led me to choose teaching and physics as a profession.” + +It was during this period that Carola made the pivotal decision to pursue physics at the University of Campinas (Unicamp). At the age of 21, she achieved a significant milestone by becoming the youngest woman to hold a position at the Gleb Wataghin Institute of Physics within the Department of Cosmic Rays and Chronology at Unicamp. Her academic journey led her to a particular interest in the field of matter structure, a subject she explored under the mentorship of César Lattes, a highly respected Brazilian physicist known for his contributions to cosmic-ray physics. César Lattes played a pivotal role in the discovery of the pion (known as pi meson at that time) in 1947, a groundbreaking achievement that led to the Nobel Prize in Physics for Cecil Frank Powell [1]. It was under Lattes’ guidance that she took her initial steps into the world of cosmic-ray research. + +In 1974, she published as co-author a paper in collaboration between Brazil and Japan. This research focused on the detection of cosmic rays in the high-altitude region of Chacaltaya, nestled in the Bolivian Andes [2]. In 1982, Carola achieved her PhD, which focused on estimating the absolute vertical flux of the electromagnetic component of cosmic radiation at Chacaltaya. This estimation was based on meticulous measurements and an in-depth analysis of electromagnetic cascades detected in photoemulsion chambers and lead. + +In the 1980s, as a part of the Pamir, Mt. Fuji, and Chacaltaya Collaborations, she participated in numerous investigations that delved into the intriguing realm of nuclear interactions. These studies harnessed the power of joint emulsion chambers in mountain-based experiments and significantly expanded our comprehension of how cosmic rays interact with the Earth’s atmosphere [3] [4]. + +Carola further advanced her academic journey with two postdoctoral studies in Germany. Her first postdoctoral stint took place at Ruprecht-Karls-Universität Heidelberg in 1989, where she engaged in research and work related to the physics of elementary particles and fields. Following that, in 1996, she embarked on her second postdoctoral experience at Forschungszentrum Karlsruhe, where she continued her in-depth exploration of the fascinating world of elementary particles and fields. Later, Carola became an integral member of the Pierre Auger Collaboration at its inception, contributing to its construction and operation across various working groups. The Pierre Auger Observatory measures extremely high-energy cosmic rays, the parent population of the gamma rays observed by the CTAO. + +While Carola’s association with Unicamp as a professor dates back to 1974, she obtained the status of a full professor in 2016. Reflecting on this milestone, Carola says, “Our institute went many years without having a female full professor. Many female colleagues asked me to participate in the competition, as  a way to pave the path for women in physics at Unicamp.” + +It was a crucial moment in her career when she transitioned from student to colleague of her mentor, César Lattes. She fondly remembers one instance, in 1974, at the very beginning of her career “Professor Lattes  invited me to teach his classes. He was present in the room and in each one I learned new things, but it was also a great challenge. Teaching students is one thing, but teaching with Professor Lattes watching is another,” she recalls. + +In one of these classes, the young teacher made a deduction on the board and Professor Lattes said that that wasn’t the best way to deduce and asked her to do it in another way. “The class collapsed. I erased it and started again. I deduced everything he had asked me for and when I finished, he said: ‘I think your way is better.’ The class laughed and was very positive in terms of learning. I was able to show that there are several ways to arrive at a result,” she says. + +Professor Carola Dobrigkeit is still showing us that there is more than one way to obtain a result, both in life and in work. Her distinguished career is a testament to her unwavering determination and boundless passion for unravelling the Universe’s secrets. Her extensive contributions to high-energy cosmic rays and particle physics [5] have not only pushed the frontiers of human understanding but have also broken down barriers related to gender in the scientific realm. Carola Dobrigkeit’s work serves as a powerful reminder of humanity’s innate curiosity and our relentless pursuit of knowledge about the enigmatic cosmic wonders that encompass our planet. + +— + +*Written by Daniela Zigante, Journalist of the CTAndo Group, Insitute of Physics of São Carlos, University of São Paulo (Brazil).

His daily work and his participation in global conferences and meetings is breaking the stereotypes, proving, again, that people with a disability can contribute at the highest level. He has become a reference for other professionals with a seemingly limiting disability.

His project, “[Astroaccesible](http://astroaccesible.iaa.es/),” is an initiative to bring astronomy and other sciences to the blind and visually impaired community in a more accessible way and to promote the adoption of inclusion criteria among other scientists, science communicators and teachers. He seems to have boundless energy in his charge: Countless talks and articles; workshops with tactile models to “touch” the firmament or walk through the Solar System; audio descriptions of astronomical objects; innovative uses of sonification; planetarium programs; inclusive visits; training and awareness courses; invitations to leading scientific communication conferences, etcetera, etcetera, etcetera. Add his continuous presence in the media and the publication of his recent book to the list of accomplishments, and one can see how Enrique has become a leader in the science communication community. And not only because he has taught us to adapt how we communicate with an audience with visual impairment, but because, with this, he has given us all a gift: the awareness and ability to transform our work into something that is more universal and inclusive, ensuring that we engage all the human senses in making science accessible and enjoyable for all.

There, she graduated at just 14 years old and began her higher education at West Virginia State College, where she earned her degrees in mathematics and French at the age of 18. Regardless of her credentials, one of the only options available to Katherine as an African American woman was to teach [4]. Hence, once she finished her studies, she had no choice but to work under the racist and discriminatory restrictions of the time. As a teacher of mathematics, music and French, she earned less money than her white peers and had to hide her marriage, since married women were not allowed to teach [5].[/vc_column_text][vc_column_text]Sometime later, she learned that the National Advisory Committee for Aeronautics (NACA), predecessor of National Aeronautics and Space Administration (NASA), was looking for African American women for calculation tasks in the Department of Guidance and Navigation, and decided to sign up [4]. At that time, African Americans were separated from white people: they had segregated cafeteria tables, bus seats, bathrooms and were prohibited from mixing whatsoever [5]. + +Her job was to perform calculations and checks for aeronautical engineers, a quiet job done by a quiet group of women.

There was not, so she began attending those meetings [4] and, over time, her persistence, math skills and quality work built her a reputation at NACA/NASA. She participated in NASA’s Mercury Project, performing by hand the calculations that allowed Alan B. Shepherd, the first American in space, to make his space journey in 1961 [3]. Later, in 1962, when computers began to be used for these types of calculations, Katherine assumed a supervisory role. The same year, her skills helped John Glenn become the first American to orbit the Earth [3, 6]. Moreover, her calculations were key to the success of the Apollo 11 mission in 1969, which landed humankind on the Moon [3].

Maria Salomea Skłodowska–Curie was the first woman to win the Nobel Prize, the only woman to do so twice and the only person to obtain it in two different scientific disciplines: physics and chemistry [1] + +Marie and her husband, Pierre Curie, were two of the pioneers in the study of radioactivity. At the end of the 19th century, Antoine Henri Becquerel discovered that uranium emitted a type of radioactivity similar to X-rays, but its true nature was unknown. Fascinated by this new discovery, the Curies dedicated their life to studying radioactive elements and the origin of radioactivity, leading to a completely different comprehension of the atoms [2]. This is the part of the story we all know, and that made Marie Curie famous around the world. There is a lesser-known part of the story, documented in Marie’s laboratory notebooks and narrated by her daughter Eve in the book “Madame Curie. A biography” [3]. The story involves Cherenkov radiation – the same radiation used by the CTAO telescopes to study the high-energy gamma-ray Universe. + +But let’s start with some scientific context. The radioactive materials, as those studied by Marie Curie, are formed by heavy atoms with nuclei composed of a large number of protons and neutrons that tend to “decay” spontaneously. In such elements, the ratio between the number of protons and neutrons is not energetically optimal, and the nucleus cannot be held together anymore. At that point, the nucleus needs to release energy to go back to a stable status. This is the so-called radioactive decay. Since energy can neither be destroyed nor created, but it can be converted, the atom reaches that stable energy by emitting either a photon or a particle. Through her examination of uranium, Marie proposed that this emission originated naturally and inherently from the atoms themselves, rather than being caused by external interactions. This hypothesis played a significant role in supporting the idea that atoms were divisible, a concept that had not yet been firmly established. + +Today this is widely accepted, but, at the beginning of the 20th century, many of these physical mechanisms were not yet known, especially when involving atomic and subatomic phenomena and their interaction with light. When working with such a complex phenomenon, it is normal to be able to observe it without knowing how to explain it, especially if you are exploring the phenomenon for the first time ever, as in the case of the Curies! + +Two radioactive elements that undergo this decay are polonium and radium, discovered by the Curies [4]. Marie once said: “Prodigious radium! Purified as a chloride, it appeared to be a dull white powder, which might easily be mistaken for common kitchen salt” [3]. So powerful, so complex, and yet, the solution of radium was simply the powder dissolved in water. + +Today, we know that, in its decay, radium emits a helium nucleus (commonly known as “alpha particle”), giving rise to a chain of lighter nuclei and eventually electrons, which can move faster than light in the medium in which it is emitted (such as water). When this happens, a bluish light is emitted. Marie did not know it at the time, but she was looking at what years later would be known as the Cherenkov effect. + +In 1910, Marie Curie, in fact, noticed the strange blue light and wrote in her notebook: “Nor was this the end of the wonders of radium. It also gave phosphorescence to a large number of bodies incapable of emitting light by their own means” [3, 5]. She wrongly attributed this blue emission to phosphorescence, which was the only phenomenon known at that time. However, the truth was that she was observing Cherenkov radiation, which would be officially discovered in 1934. Therefore, Marie Curie was one of the first people to observe Cherenkov radiation, albeit unknowingly. There were several others who came across this elusive radiation. In 1888, Oliver Heaviside wrote about it in a scientific paper *(a)* that was mostly disregarded: “If the speed of the motion exceeds that of light, the disturbances are wholly left behind the charge, and are confined within a cone.” And, in 1904, Arnold Sommerfeld theoretically predicted Cherenkov radiation, as well. But, once again, the scientific community missed the clue. It was not until 1922 that Marie’s French colleague, Leon Mallett, began studying the phenomenon, albeit still without much fortune. We had to wait another decade for the studies of Tamm, Frank, Vavilov and Cherenkov in 1934 to finally establish the true nature of this radiation [6]. + +And what was so overlooked in the 20th century has now opened a new window of science: astroparticle physics, the newest field in astronomy and astrophysics. Cherenkov light can also be produced in the air when a gamma ray (photons, or light, with extremely high energy) arrives in the Earth’s atmosphere and produces a particle shower. These particles move faster than the speed of light in the air of the atmosphere giving rise to this bluish flash of light: Cherenkov light. It lasts barely a billionth of a second, so we cannot see it with our eyes, but with Cherenkov telescopes we can. And the CTAO will use these telescopes to unravel the high-energy Universe. From a dim light in Marie’s lab to opening a new field of study. + +In Marie Curie’s own words *(b)*: “I am among those who think that science has great beauty. A scientist in his laboratory is not only a technician: he is also a child placed before natural phenomena which impress him like a fairy tale. We should not allow it to be believed that all scientific progress can be reduced to mechanisms, machines, gearings, even though such machinery also has its beauty.” + +— + +*Article reviewed by **Anna Wolter, researcher at the INAF Osservatorio Astronomico di Brera (Italy).* + +*References* + +1.

Through her passion for science, she has left a permanent mark on the exploration of the Universe, and her brilliant legacy lights the path for future generations. + +Sandra Moore Faber was born in Boston, Massachusetts on December 28, 1944 [1]. From an early age, her interest in science and astronomy grew despite the low representation of women in this discipline in the 60s. Her deep interest in this subject led her to become one of the most prominent figures of contemporary astronomy. + +Sandra completed her bachelor’s degree in Astronomy at Swarthmore College in 1966 and subsequently earned her Ph.D. at Harvard University in 1972 [1], specializing in Optical Observational Astronomy under the direction of I. John Danziger [2]. That same year, she joined the faculty at the Lick Observatory at the University of California, Santa Cruz, becoming the first woman to serve on the staff. Her research focused on using the lookback power of large telescopes to study the formation and evolution of galaxies [3]. + +In 1976, one of Sandra’s investigations, which consisted of observing the relationship between the brightness and spectra of galaxies and the orbital velocities and movements of the stars within them, resulted in the discovery of the Faber-Jackson relationship. This relationship assumes a direct connection between the galaxy’s brightness and its stars’ dispersion speed [4]. This means that if we know the dispersion speed of stars in a galaxy, we can estimate their luminosity. The Faber-Jackson relationship is essential in astronomy since it allows us to measure the masses of galaxies more precisely. By knowing how massive galaxies are, we can better understand how they formed and evolved. + +In 1979, Faber and John S. Gallagher published a paper that presented a review of the evidence for the existence of dark matter [5]. This paper is regarded among astronomers as the turning point in the quest to determine whether 80 percent of the mass in the Universe is “missing”—mysterious, invisible and impervious to direct detection. This discovery of large amounts of dark matter (using indirect methods of detection) in a certain exotic species of galaxy led Sandra to conclude, in a paper of 1983 with UCSC astronomer Douglas Lin, that dark matter could not be neutrinos, subatomic particles that travels close to the speed of light (“hot,” in cosmological terms), but might be another species of subatomic particle, not yet known, that travels at a much slower rate (“cold”) [6]. + +On the other hand, Sandra played a fundamental role in large-scale projects, such as her contribution to installing the Keck Observatory in Hawaii, one of the biggest optical telescopes in the world. Her involvement in projects with the Keck telescope includes research on galaxy dynamics, the detection of supermassive black holes and the evolution of galaxy clusters. + +Additionally, she is recognized in her field for her contributions to the design and use of large telescopes. For example, Sandra was part of the design team for the Hubble Space Telescope’s Wide-Field Camera [7] and is the principal investigator of the DEIMOS (Deep-Imaging Multiobject Spectrograph) project [7]. She was also the co-principal investigator of the CANDELS Research Team [8], which used the Hubble Space Telescope to investigate galaxies in their initial stages of formation. + +As a result of her outstanding academic and professional career, Sandra has received numerous awards and recognitions, including the U.S. National Medal of Science (2013) [9], the Gruber Prize in Cosmology (2017) [7] and the Gold Medal of the Royal Astronomical Society of the UK (2020) [10]. + +And Sandra has transmitted her wisdom and experience through teaching, too. She has been a professor at the University of California at Santa Cruz, teaching core subjects and guiding students in her research. She also holds the title of Professor Emerita at this university [3], where she has left an indelible mark on the academic and scientific community. + +Sandra Faber’s legacy transcends her gender and inspires us all, regardless of our circumstances or obstacles. Her story reminds us that with passion, perseverance and commitment we can reach for the stars, both figuratively and literally. Her life is a powerful reminder that there are no limits that cannot be overcome in the search for knowledge.

They originate from very energetic particles and, as such, provide glimpses into extreme astrophysical phenomena. Among the most extreme sources in the Universe, gamma-ray bursts (GRBs) lead the pack. They are produced following the formation of jets traveling with velocities close to the speed of light ejected by newly-born compact objects (such as neutron stars or black holes, see Figure 1). Thanks to observations from ground-based telescopes and space missions, we know that GRBs produce an emission over a wide range of frequencies, from the radio band up to gamma-ray energies. Most of this emission is thought to be synchrotron radiation from energetic electrons moving in spiral pattern around magnetic field lines. At very high energies (VHE, >100 GeV) synchrotron radiation is not expected to play a role, but other mechanisms have been theorised to produce a detectable amount of VHE radiation. The most important one is the Inverse Compton, where photons collide with the energetic electrons and gain energy in the process. This mechanism can be more or less relevant, depending on the conditions of the region where the radiation is produced, which in GRBs are still poorly understood. + +Curiously, even though GRBs are the most powerful sources in the Universe, all the efforts to detect VHE radiation arising from them have failed for many years. Considering that GRBs are cosmological sources located at an average redshift of z=2, the flux of VHE photons (if produced) will be strongly attenuated by the encounter with visible-IR light, making their detection on Earth very difficult. Thus, the question whether this radiation is produced or not, in what amount, how common it is, and which maximum energies can be attained remained unanswered for a long time. As a consequence of these uncertainties, the role of CTA on the study of GRBs was not easy to predict. On the one hand, CTA’s sensitivity down to 20 GeV assures that GRBs can be detected, since the existence of emission at these energies has already been proven by the satellites *Fermi* and AGILE. On the other hand, the detection rate and the energy up to which GRBs will be detected strongly depend on whether or not an emission component at VHE exists. + +Since January 2019, CTA predecessors MAGIC and H.E.S.S. have announced detections of radiation well above 100 GeV from three GRBs [1,2,3], finally proving that this kind of radiation is indeed produced and might be a quite common component in the radiative output of GRBs. Thus, the consequences on the prospects for GRB detections with CTA are enormous. In light of these recent discoveries, it is reasonable to expect that GRBs will be interesting targets both for the Large-Sized Telescopes (LSTs) and the Medium-Sized Telescopes (MSTs), responsible for low and medium-energy sensitivities of CTA (from approximately 20 GeV to a few tens of TeV in total). The lower energy threshold assures that, compared to the GRBs detected by MAGIC and H.E.S.S. (located at z=0.0785, z=0.424 and z=0.653), CTA will be able to detect signals from even greater distances, where the GRB rate is higher. Finally, the long-lasting duration of the VHE emission (detected up to several hours [2]), coupled with CTA’s unprecedented sensitivity, implies that GRBs that can be pointed only several hours after the initial burst might still be well detectable. The GRB detection rate at VHE is then expected to largely increase with CTA, enabling researchers to fully exploit this new window of investigation on GRBs. + +CTA observations are expected to have a large impact on GRB science and provide information on the amount of energy carried by the VHE component, its spectral shape and temporal evolution, and on the presence of internal absorption affecting the intrinsic spectral shape. These observations can be used to unveil important physics, such as the source density and magnetic field strength, the energy of the emitting electrons, and the jet Lorentz factor (i.e. the velocity of the jet), thus bringing new information on shock wave physics, GRB environments and jet properties. + +In light of the MAGIC results on GRB 160821B [4], the prospects for detection of VHE radiation from short GRBs are also very promising. Because short GRBs are connected to the same sources that produce gravitational waves, there is a direct link between CTA science and gravitational waves, which strengthens the role of CTA in this exciting new era of multi-messenger astrophysics. + +[1] [Mirzoyan et al.

No re-alignment of the telescope optics was required following the mounting of CHEC. Images appear clear and in-focus with the PSF of the telescope well-matched to the camera pixel size. A selection of these events can be seen below. + +The observations took place at the astronomical site of Serra La Nave (Mount Etna) in Sicily managed by INAF-Catania and involved both CHEC and ASTRI team members from DESY, INAF, University of Leicester, Liverpool University, [Max-Planck-Institut für Kernphysik](https://www.mpi-hd.mpg.de/mpi/en/hinton/projects/cta/chec/) (MPIK) and the University of Oxford. The team remained on site for two weeks to prove the viability of using CHEC with ASTRI – a goal that was readily met. Beyond capturing Cherenkov images from cosmic rays, the team briefly observed several gamma-ray sources, commissioned the internal camera calibration system, took data to verify the camera pointing system and completed work on reading out trigger patterns for each raw event.[/vc_column_text][vc_column_text] + +This achievement comes not long after the ASTRI-Horn telescope became the first Cherenkov telescope in a dual-mirror configuration to detect the Crab Nebula at TeV energies using the ASTRI prototype Cherenkov camera. The CHEC is an alternative Cherenkov camera compatible with both SST dual-mirror telescopes, GCT and ASTRI. The latest prototype, CHEC-S (right) consists of 2048 silicon photo-multiplier pixels forming approximately a 9o x 9o field of view when installed on ASTRI-Horn. + +The CHEC is unique as an SST dual-mirror camera in its ability to capture Cherenkov light not as fixed images, but as movies consisting of hundreds of frames each lasting one billionth of a second. This can be seen clearly in the selection of Cherenkov events shown in the animated gif below. On the left, the time development of individual showers can be seen as they sweep across the camera, whilst, on the right, the resulting extracted charge for each pixel for the corresponding images is shown. The majority of these images result from showers initiated by cosmic rays of several hundred TeV landing several hundred metres from the telescope. + +Two things are immediately clear from such images. First, looking at the right, there is an ambiguity in the fixed image – it is not easy to tell from which direction it originated. Think of a perfectly symmetric train – how can you tell which end is the front? The answer is that you need to see it move. The same is true here, and this ambiguity is removed by the additional timing information evident in the images to the left – we can now tell without question from which direction the Cherenkov light came. Second, each of these images lasts 128 nanoseconds. That allows Cherenkov light to propagate across the full camera without truncation, something that has not been possible with previous generations of Cherenkov cameras. + +“The integration of CHEC-S on ASTRI has been extremely smooth. We have proved that the teams can work together efficiently and that CHEC works well on an ASTRI-style dual-mirror telescope,” said Richard White, Group Leader at MPIK and coordinator of the CHEC project. “We see clean, crisp Cherenkov images swimming across the camera, and results look to be almost exactly as expected from Monte Carlo simulations. Both teams have worked hard to make this a reality, and I am extremely grateful for their efforts.” + +A second campaign is planned for mid-June, when the CHEC and ASTRI teams will attempt moon light observations in an important step towards verifying some of the most stringent CTA requirements. In the meantime, analysis is underway on the wealth of data collected so far. Beyond this, an iteration of CHEC is planned to incorporate the latest in SiPM technology. + +Three classes of telescope are required to cover the full CTA very-high energy range (20 GeV to 300 TeV): Medium-Sized Telescopes (12 m diameter reflector) will cover CTA’s core energy range (100 GeV to 10 TeV) while the Large-Sized Telescopes (23 m) and Small-Sized Telescopes (4 m) are planned to extend the energy range below 100 GeV and above a few TeV, respectively. The ASTRI telescope and CHEC camera are proposed SST designs being prototyped and tested for CTA’s southern hemisphere array. + +The ASTRI project ([http://www.brera.inaf.it/astri/](http://www.brera.inaf.it/astri/)) is led by the [Italian National Institute of Astrophysics (INAF)](http://www.inaf.it/en?set_language=en) with the collaboration of a number of Italian universities, the [Italian National Institute of Nuclear Physics (INFN)](https://web2.ba.infn.it/index.php/en/), [Universidade de São Paulo](http://www.ifsc.usp.br/) in Brazil and [North-West University](http://www.nwu.ac.za/) in South Africa. The CHEC project, led by [MPIK](https://www.mpi-hd.mpg.de/mpi/en/hinton/projects/cta/chec/), is an international collaboration between the University of Adelaide, the University of Amsterdam, DESY Zeuthen, Durham University, the Erlangen Centre for Astroparticle Physics (ECAP), the University of Leicester, the University of Liverpool, Nagoya University, and the University of Oxford. + +The SSTs will outnumber all the other telescopes with 70 planned to be spread out over several square kilometres in the southern hemisphere array. Since the showers generated by very high-energy gamma-rays (between a few TeV and 300 TeV) produce a large amount of Cherenkov light, it is sufficient to build telescopes with small mirrors to catch that light. The SSTs’ wide coverage and large number, spread over a large area, will improve CTA’s ability to detect the highest energy gamma rays. + +Find more technical information on CHEC in:  White, R. et al.

The [CTA Consortium](https://www.ctao.org/partners/ctao-consortium/) is the group of scientists and engineers that devised the CTA concept more than a decade ago and have been the driving force behind its design. When the Consortium was formed in 2008, the primary goal was the design and promotion of a next generation Cherenkov telescope instrument that can address the many open questions that exist in high-energy astrophysics. At that time, issues like data access and data rights, writing observation proposals and dealing with commissioning and early operations were not the main focus. + +Today, the Consortium is composed of more than 1,500 members from 200 institutes in 31 countries.

The parallel sessions were followed by a one and a half day plenary session and concluded with a meeting of the Consortium Board, the governing body of the CTA Consortium. + +The plenary session was opened with an inspiring presentation given by Thomas Schulthess, director of the Swiss National Supercomputing Centre (CSCS) and professor for computational physics at ETH Zürich, who explained the convergence between High Performance Computing and Big Data, and the role of the CSCS. The session featured also a highlight talk by Matteo Balbo on Eta Carinae, summarising the science questions related to colliding wind binaries and demonstrating the science potential of CTA in this area. In his introductory talk, Werner Hofmann, Spokesperson of the CTA Consortium, also underlined the eagerness of the community to get CTA data. This was attested by the great success of the first CTA Science Symposium that took place in Bologna in May, which illustrated the many links that exist between CTA science and evolutions in other fields. + +The Consortium was also informed about the status and outcomes from the various telescope prototypes. Highlights included the exciting progress of the LST-1 commissioning on La Palma, the first light of the NectarCAM Qualification Model on the Medium-Sized Telescope prototype in Berlin Adlershof and the detection of the Crab nebula by the ASTRI-Horn telescope on Mount Etna. Abelardo Moralejo and Johan Bregeon, respectively Coordinator and Deputy Coordinator of the Analysis and Simulations Working Group, showed interesting comparisons of prototype data with data from Monte Carlo simulations, illustrating the good understanding of the hardware. The understanding will even improve, thanks to a dedicated and impressive effort to refine the Monte Carlo model in collaboration with the telescope teams. Progress was also reported on the development of the software pipeline that processes CTA data from levels DL0 to DL3 and also produces the Instrument Response Functions. A reference analysis, including analysis benchmarks, is being established so that improved algorithms can be evaluated and subsequently proposed for integration into the pipeline. + +The Science Working Groups also made impressive progress, as summarised in the presentation of Emma de Oña Wilhelmi, Science Coordinator of the CTA Consortium. The group worked intensively on the identification of multi-wavelength and multi-messenger needs for the Key Science Projects, which now have to be prioritised to develop a suitable strategy. Substantial progress was also made on the Consortium Publications, with the first papers being scheduled for submission within the next months. Details on the two most advanced Consortium papers, relating to searching for dark matter in the Galactic Centre and the propagation of very high-energy gamma rays across intergalactic space, were given in dedicated plenary talks. + +Significant progress was also observed on the side of the CTA Observatory (CTAO). Federico Ferrini, Managing Director of the CTAO gGmbH, informed the Consortium about the progress in the transformation of the current CTAO gGmbH into a European Research Infrastructure Consortium (ERIC), about the kick-off of the activities for the implementation of CTA-South, and about the establishment of the CTA cost book that will serve as a reference for the future in-kind contributions to the project. In his presentation, Wolfgang Wild, Project Manager of CTA, summarised the progress on the implementation of CTA-North, CTA-South and the Science Data Management Centre (SDMC). Furthermore, he covered various project related topics, including project management and systems engineering activities, construction milestones and the SST harmonisation process. Finally, he took the occasion to thank the outgoing Project Scientist Jim Hinton for his important contributions to CTA and welcomed the new Project Scientist Roberta Zanin, who joined CTAO on 1 June 2019. Roberta gave a short presentation about the Project Science activities, including progress on requirements and science operations, as well as plans on the second Data Challenge and science verification. + +Additional plenary presentations by CTAO personnel covered systems engineering, infrastructure, computing, communication and outreach. Systems engineering is finalising the design for CTA-North, of which many results will be directly applicable to the design of CTA-South. Also, Critical Design Reviews for the LST and the MST structure are scheduled. Infrastructure planning for the short project in the North that includes three LSTs and one MST are progressing well, with start of the civil work expected in the first half of 2020. In addition, with Paolo Calisse for CTA-North and Volker Heinz for CTA-South, site managers are now installed who are already quite active with the preparation of the site activities. The CTAO computing department, which is now led by the computing coordinator Stefan Schlenstedt, has the challenging task to get software and computing infrastructure ready for the first telescope acceptance in 2020 and the planned start of early science in 2022. A lot of work still needs to be done concerning the detailed system definition, requirement and interfaces, but formal development of the array control software (now called ACADA) will start soon. The outreach and communications office is also very active, and CTA is getting steadily increasing reach on the web, in social media, but also in the press and during conferences. Outreach and communications planning is also well under way, and a plan exists now covering the construction phase of CTA. + +In its meeting on Friday, the Consortium Board discussed among other items the transition towards the new CTA Consortium. A new Memorandum of Understanding (MoU) was agreed upon at the last Consortium meeting in Berlin, and its signature has started on 24 May 2019. While the current MoU is based on the admission of institutes, the new MoU is based on the admission of individuals and their commitments on fulfilling CTA Consortium duties, such as contributions to the Science and Analysis and Simulations Working Groups, but also contributions to the development and construction of CTA elements and the development of analysis methods and tools. The new CTA Consortium is expected to be kicked-off by the time of the next Consortium meeting, but the completion of the transition to the new Consortium is expected to take probably more than one year. + +The meeting featured also visits to the impressive CSCS, where attendants could have a look on Piz Daint, the most powerful supercomputer in Europe. A press event was furthermore organised during the meeting that highlighted the Swiss contribution to the exploration of the high-energy Universe, and the Swiss involvement in CTA. A relaxing conference dinner was organised on Wednesday near the lake at the foot of Monte San Generoso, where besides an excellent dinner, the attendants could benefit from a spectacular view on the mountains around Lugano. + +The Lugano Consortium meeting was an excellent event, and in the name of the entire Consortium, I would like to warmly thank the organisers and sponsors for their hospitality and the seamless organisation of an unforgettable week. diff --git a/src/content/news/cta-consortium-holds-bi-annual-meeting.md b/src/content/news/cta-consortium-holds-bi-annual-meeting.md new file mode 100644 index 0000000..f9f74a6 --- /dev/null +++ b/src/content/news/cta-consortium-holds-bi-annual-meeting.md @@ -0,0 +1,27 @@ +--- +title: "CTA Consortium Holds its Bi-annual Meeting in Orsay, France" +description: "During the week of 14 May, the CTA Consortium held its bi-annual meeting in France on the campus of Orsay, south of Paris.

With its ability to cover an enormous range in photon energy from 20 GeV to 300 TeV, CTA will improve on all aspects of performance with respect to current instruments. And its wider field of view and improved sensitivity will enable CTA to survey the sky hundreds of times faster than previous TeV telescopes. + +“The CTA Science Symposium is really our opportunity to bring a wide-range of experts together to discuss the future of high-energy astrophysics and particle physics from the viewpoint of many different wavelengths,” said Stefan Funk, Chair of the Scientific Organizing Committee. “We see this as our chance to engage the users and the future users of CTA data now in the hopes that we can serve a variety interests and scientific needs.” + +The event will be held in the historic centre of Bologna, Italy at the Teatro Duse. Registration and the call for contributed talks are now open. If you register before 5 April, the fee is 300 euro (200 for students). After 5 April, the fee will be raised to 350 and 250 euro respectively.  This covers all lunches, coffee breaks and dinner at the beautiful [Palazzo Re Enzo](http://www.palazzoreenzo.com/en/). + +Talks may cover the following areas: cosmic particle acceleration, compact objects and relativistic shocks, role of cosmic particles in galaxy evolution and star-forming systems, gamma rays as cosmic probes, fundamental physics, multi-wavelength and multi-messenger observations and, additionally, any topic connected to the scientific possibilities of CTA.

The recorded images have approximately the same angular size, each one from a different observational direction in the field of view (from 0 to 4.5 degrees from each side with respect to the central optical axis). These images show that the optical point-spread function of the telescope is approximately constant across the full field of view. This information will allow scientists to reconstruct the direction of gamma-ray photons emitted from celestial sources. + +“This is also the first time that a Cherenkov telescope with two focusing mirrors has been completely characterized from the opto-mechanical point of view,” said Giovanni Pareschi, astronomer at the INAF-Brera Astronomical Observatory and principal investigator of the ASTRI project. “This is an important result because it allows us to move immediately to the next step: to mount a Cherenkov camera by December 2016 with the aim to observe the first gamma-ray light with ASTRI.” + +The ASTRI project is led by the [Italian National Institute of Astrophysics (INAF)](http://www.inaf.it/en?set_language=en) with the collaboration of a number of Italian universities, the [Italian National Institute of Nuclear Physics (INFN)](https://web2.ba.infn.it/index.php/en/), [Universidade de São Paulo](http://www.iag.usp.br/) in Brazil and [North-West University](http://www.nwu.ac.za/) in South Africa. + +The SSTs will outnumber all the other telescopes with 70 planned to be spread out over several square kilometres in the southern hemisphere array.

Pushing back the frontiers in astronomy always leads to something truly new and exciting, and now we’re all just itching to get started.” + +It has been a decade since science planning for CTA started, resulting in a series of publications in a special edition of [Astroparticle Physics](http://www.sciencedirect.com/science/journal/09276505/43) in 2013. The current work began that same year with an organized effort by the CTA Consortium to develop CTA’s Key Science Projects (KSPs) in 2013. After three years of development and refinement that included internal and external reviews, the KSPs were incorporated into a single document: *Science with the Cherenkov Telescope Array*. diff --git a/src/content/news/cta-representatives-meet-local-officials-la-palma-discuss-northern-hemisphere-array.md b/src/content/news/cta-representatives-meet-local-officials-la-palma-discuss-northern-hemisphere-array.md new file mode 100644 index 0000000..6002a5c --- /dev/null +++ b/src/content/news/cta-representatives-meet-local-officials-la-palma-discuss-northern-hemisphere-array.md @@ -0,0 +1,19 @@ +--- +title: "CTA Representatives Meet with Local Officials in La Palma to Discuss Plans for Northern Hemisphere Array" +description: "During the week of 17 July, representatives from the CTAO gGmbH and its Project Office visited the Canary Islands (Tenerife and La Palma) to meet with its hosting partner, the Instituto de Astrofisica de Canarias (IAC), and local…" +date: 2017-07-28 +category: news +author: CTAO +cover: /uploads/IMG_7254-copy2.png +draft: false +--- + +During the week of 17 July, representatives from the CTAO gGmbH and its Project Office visited the Canary Islands (Tenerife and La Palma) to meet with its hosting partner, the [Instituto de Astrofisica de Canarias](http://www.iac.es/index.php?lang=en) (IAC), and local authorities to establish and build relationships, and to discuss the strategy and technical plans for CTA’s [northern hemisphere array](https://www.ctao.org/emission-to-discovery/array-sites/ctao-north/) on La Palma. + +After meetings in Tenerife with the IAC and the Large-Sized Telescope (LST) and Medium-Sized Telescope (MST) teams earlier in the week to discuss the overall strategy for site infrastructure and construction, the CTAO team (Managing Director Ulrich Straumann, Infrastructure Coordinator David Bristow, Power and Data Network Planner Carla Crovari and CAD technologist Stephen Brown) visited the site of the LST prototype on La Palma.

More than 1,500 people working in different international teams contribute to the implementation of the CTAO, as well as to its scientific, software and hardware development. + +The CTAO was included in the 2008 roadmap of the European Strategy Forum on Research Infrastructures (ESFRI) and promoted to a Landmark project in 2018 and is a top-ranked priority amongst new ground-based infrastructure projects in ASTRONET’s “Roadmap 2022-2035: A Strategic Plan for European Astronomy.” + +The CTAO SDMC is one of the Observatory’s four facilities. Located on the Deutsches Elektronen-Synchrotron DESY campus in Zeuthen, Germany, it serves as the scientific gateway for data received from the two telescope arrays and will coordinate both software and computing efforts, making CTAO’s data products available to the worldwide community. This approach stems from CTAO’s commitment to Open Science, making it the first observatory of its kind to operate as an open, proposal-driven observatory providing public access to its high-level science data and software products. + +The CTAO SDMC will be the home of the CTAO Computing Department. From handling the proposal submissions to the dissemination of data to scientists, the computing team is working to develop a package of hardware and software products to support the flow of data.

The CTAO’s unparalleled accuracy and broad energy range (20 GeV- 300 TeV) will provide novel insights into the most extreme and powerful events in the Cosmos, addressing questions in and beyond astrophysics falling under three major themes: Understanding the origin and role of relativistic cosmic particles, probing extreme environments (such as black holes and neutron stars) and exploring frontiers in physics (such as the nature of dark matter). To do so, the CTAO has two telescope array sites: CTAO-North in the northern hemisphere at the Instituto de Astrofísica de Canarias’s (IAC’s) Roque de los Muchachos Observatory on La Palma (Spain), and CTAO-South in the southern hemisphere near the European Southern Observatory’s (ESO’s) Paranal Observatory in the Atacama Desert (Chile). The headquarters is hosted by the Istituto Nazionale di Astrofisica (INAF) in Bologna (Italy), and the Science Data Management Centre (SDMC) is hosted by the Deutsches Elektronen-Synchrotron (DESY) in Zeuthen (Germany). The CTAO will also be the first observatory of its kind to be open to the worldwide scientific communities as a resource for data from unique, high-energy astronomical observations. + +The Board of Governmental Representatives (BGR) is the committee preparing for the CTAO’s legal status transition, formed by 12 countries and one intergovernmental organisation: Australia, Austria, Brazil, Czech Republic, European Southern Observatory (ESO), France, Germany, Italy, Japan, Poland, Slovenia, Spain and Switzerland.

In total, we expect to be able to detect about 500 individual sources of gamma-ray emission in the course of the survey. An important fraction of these sources will be spatially resolved by CTA, providing insights into the physics that accelerate particles to the highest energies and how these particles leave their accelerating sources. + +It also is expected that the survey will lead to the discovery of new and unexpected phenomena in our Galaxy, such as new source classes and new types of transient phenomena. The detection of hundreds of new very-high-energy gamma-ray sources will substantially increase the galactic inventory and permit high statistics population studies for the first time. The survey also will be fundamental to unveiling sources that are capable of accelerating particles to PeV energies, which is key to understanding the origin of the cosmic rays that permeate our Milky Way. diff --git a/src/content/news/el-universo-que-veremos-event.md b/src/content/news/el-universo-que-veremos-event.md new file mode 100644 index 0000000..a81eb47 --- /dev/null +++ b/src/content/news/el-universo-que-veremos-event.md @@ -0,0 +1,39 @@ +--- +title: "The Astronomical Infrastructures of the Future Meet in Granada" +description: "On Wednesday, 5 October, the heads of the Cherenkov Telescope Array Observatory (CTAO), the European Southern Observatory (ESO) and the Square Kilometre Array Observatory (SKAO) met at the headquarters of the Institute of Astrophysics of…" +date: 2022-10-06 +category: news +author: CTAO +cover: /uploads/Instituto-Astrofisica-5-10-22-A-135-de-169-scaled-1-1600x1004.jpg +draft: false +--- + +Re-play the event [on YouTube](https://youtu.be/4-90-PjQvts). + +More photos [on our Flickr channel.](https://www.flickr.com/photos/cta_observatory/albums/72177720302769042) + +On Wednesday, 5 October, the heads of the Cherenkov Telescope Array Observatory (CTAO), the European Southern Observatory (ESO) and the Square Kilometre Array Observatory (SKAO) met at the headquarters of the Institute of Astrophysics of Andalusia (IAA-CSIC) in Granada, Spain to participate in the round table “El Universo que veremos” (“The Universe that we will see,” in English). Xavier Barcons (Director General of ESO), Philip Diamond (Director General of SKAO) and Wolfgang Wild (CTAO Project Manager) discussed the science, technology, impact and governance of these three major astronomical infrastructures, in a session moderated by Isabel Márquez (Deputy Director of the IAA-CSIC) and organized jointly between the IAA-CSIC and the CTAO.

Building and managing the largest observatories on the planet involves great technological and scientific challenges that increasingly require international collaboration. + +“It will be more and more common to combine many ranges of wavelengths to obtain a complete picture of an object or process in the Universe: multi-wavelength astronomy is the future, and it is what will allow us to fully understand these phenomena,” explained Wolfgang Wild during the round table. + +Among the technological challenges, Wild and Barcons highlighted technical challenges, such as “moving a hundred-ton telescope in twenty seconds to any part of the sky” in the case of CTAO, or “getting 798 segments of one and a half meters to work as a single mirror” in the case of the ESO’s ELT (Extremely Large Telescope), the world’s largest optical telescope that is currently being built in Chile. Diamond, for his part, emphasized the challenges that a Big Data project like SKAO must face, such as the storage, processing and conversion of the immense volume of data that the Radio Observatory will generate. + +Likewise, the speakers discussed the socio-economic impact and governance of these international infrastructures and agreed on the need to create sustainable, diverse and inclusive projects. Among other activities, Barcons and Diamond highlighted the use of solar energy: recently, ESO inaugurated a photovoltaic plant in Chile, and SKAO’s antennas will work with this type of energy in Australia and mostly in South Africa. On the other hand, Wild explained the environmental care that any construction requires, like the detailed environmental studies conducted prior to CTAO’s activities on the Spanish island of La Palma, which will be the site of the Observatory’s northern hemisphere array of telescopes.

The project — by AES Andes, a subsidiary of the U.S. power company AES Corporation — includes multiple energy and processing facilities, spread over an area of more than 3,000 hectares, the size of a small city. Its planned location is just [a few kilometers from the Paranal telescopes](https://www.eso.org/public/unitedkingdom/images/INNA-map-EN/). A preliminary analysis revealed that, due to its size and proximity to Paranal, the INNA project posed significant risks to astronomical observations. Now, an in-depth technical analysis by ESO has confirmed that INNA’s impact on the facilities at Paranal Observatory, Chile would be devastating and irreversible. + +ESO’s technical report focuses on those site characteristics that are most critical for the performance of the observatories and that could be impacted by the INNA project, concluding that the construction and operation of this project will cause artificial light contamination (“light pollution”) and an increase in ground motions or vibrations, atmospheric turbulence and dust contamination of optical surfaces. + +“ESO has done an outstanding job in conducting this thorough technical analysis, providing valuable insights into the potential impacts of the planned INNA project,” says Stuart McMuldroch, CTAO ERIC Director General. “The findings are very concerning, and we support their efforts to achieve a relocation of the planned facility.” + +According to ESO’s analysis, the industrial complex would increase light pollution above the Very Large Telescope (VLT), which is about 11km from the planned INNA location, by at least 35% above the current artificial-light baseline levels. Another of the Paranal facilities, ESO’s Extremely Large Telescope (ELT), would see the light pollution above it increase by a minimum of 5%. This increase already represents a level of interference incompatible with the conditions required for world-class astronomical observations. The impact on the skies above the CTAO-South, located just 5km from INNA, would be the most significant, with light pollution going up by at least 55%. + +“Any loss in the quality of the Chilean night skies over Paranal — no matter how small — should not be tolerated, as any science lost will be gone forever and can never be recovered,” states Roberta Zanin, CTAO Project Scientist. + +For its technical analysis, a team of experts led by ESO Director of Operations Andreas Kaufer joined forces with Martin Aubé, a world-leading expert on sky brightness at astronomical sites, to run simulations using the most advanced light-pollution models. As input, the simulations used publicly available information provided by AES Andes when submitting the project for environmental assessment, which states the complex will be illuminated by over 1,000 light sources. + +“The light-pollution figures we are reporting assume that the project will install the most modern available luminaries in a way that minimises light pollution. However, we are concerned that the inventory of light sources planned by AES is not complete and fit for purpose. In that case our already alarming results would underestimate the potential impact of the INNA project on the Paranal sky brightness,” explains Kaufer. + +In addition to the dark and clear skies, Paranal Observatory is the world’s top site for astronomy thanks to its exceptionally steady and stable atmosphere – it has what astronomers call excellent seeing conditions or very low “twinkling” of astronomical objects caused by turbulence in Earth’s atmosphere. With INNA, the best seeing conditions could deteriorate by up to 40%, in particular due to the air turbulence caused by the project’s wind turbines. + +Another worry is the impact of the vibrations caused by INNA on the VLT Interferometer (VLTI) and the ELT, which are both extremely sensitive to micro-seismic noise. The technical analysis reveals that INNA’s wind turbines could produce an increase in these micro-vibrations of the ground that is large enough to impair the operations of these two world-leading astronomical facilities. Dust during construction is also problematic as it settles on the telescope mirrors and obstructs their view. + +Furthermore, INNA’s infrastructure is likely to encourage the development of an industrial hub in the area, which could turn Paranal into an unusable site for top-level astronomical observations. + +“ESO and its Member States are fully supportive of energy decarbonisation. For us, Chile should not have to make a choice between hosting the most powerful astronomical observatories and developing green-energy projects. Both are declared strategic priorities by the country and are fully compatible — if the different facilities are located at sufficient distances from one another,” says ESO Director General Xavier Barcons. + +The full technical report will be submitted to the Chilean authorities later this month as part of the Citizen Participation Process (PAC) in INNA’s environmental impact assessment and made public at that time.

The project is led by the IN2P3, the national institute of nuclear and particle physics within CNRS, the French public research organisation, with a consortium of 31 partners including 27 European partner institutions, two pan-European research organisations, and two SMEs. + +Multi-messenger astronomy and accelerator-driven particle physics are two pillars of the ESCAPE project. Through the combination of the experimental investigations of the two extremes, from the largest-scale structures in the observable Universe to the most fundamental particles, the astronomy-related projects and the accelerator-based particle physics facilities will open together new paths towards the understanding of the Universe. A deluge of data is expected in the next years by the next generation facilities prioritised in the European Strategy Forum on Research Infrastructures (ESFRI) – the major facilities identified in the European Strategy Forum for Research Infrastructures – and other world-class projects. This €16 million funding boost will help Europe’s world-leading research infrastructures work together to find common solutions to their data challenges, their data interoperability, their data access and to accentuate the openness of Fundamental Science research to the full international community, from professionals to the public. + +“It is the first time that many of the greatest European scientific facilities in physics and astronomy have combined forces to make their data and software interoperable and open, committing to make the European Science Cloud a reality. This is an important milestone for European scientific research,” said Dr. Giovanni Lamanna, Director of the IN2P3 laboratory LAPP (Laboratoire d’Annecy de Physique des Particules) and Principal Investigator of the ESCAPE project. + +**People:** European astronomers and particle physicists are celebrating the €16 million boost for Open Science today, through ESCAPE. ESCAPE is not just about providing tools for the expert European science community.

Users are invited to contribute to define the main common functionalities of EOSC and the needs of their own community. European astronomers and particle physicists are committing to build EOSC through ESCAPE. + +**Training:** ESCAPE’s work-plan emphasises a strong component of training – the aim is to attract and educate young scientists towards Open Science and data stewardship, in using the newly developed tools and methodologies. The EOSC will be developed to serve the needs of scientists and to respond to the global cultural change recognising research data as a significant output of research that needs appropriately curated throughout and after the period conducting the research. + +**Services:** ESCAPE will extend the concepts of the astronomical Virtual Observatory seamlessly into the domains of solar physics, particle physics and astroparticle physics. ESCAPE will leverage the long-standing expertise of the particle physics community in large-scale distributed computing and data resources, building new tools to deal with the data avalanche from the next generation of facilities to create a giant “data lake” of up to multi-Exabytes federating national and regional data centres. A new science analysis platform will be built, so users of the EOSC can tap into existing software and bring their own, using the power of high-performance and high-throughput computing. Finally, ESCAPE will create a new open source software repository, to maximise software re-use and co-development, to identify open standards for software release, to investigate data mining tools and new analysis techniques. The ESCAPE domain-based repository will be part of the global EOSC catalogue of scientific software. + +**Projects:** ESCAPE builds on the successes of an earlier EU-funded cluster project, ASTERICS2, which built some of the fundamental infrastructure, data management and scientific software solutions as well as policies for interoperability and joint scheduling. + +The funding was made through the European Union’s Horizon 2020 Framework Programme, which is the biggest EU Research and Innovation programme ever with nearly €80 billion of funding over 7 years (2014 to 2020). + +**Organisations:** ESCAPE’s domain expert and skilled consortia of facilities is broad, and knowledgeable.

La sede central del CTAO está alojada en Italia en el Istituto Nazionale di Astrofisica (INAF) en Bolonia, y el Centro de Gestión de Datos Científicos (SDMC por sus siglas en inglés) se encuentra en Alemania en el campus de Deutsches Elektronen-Synchrotron (DESY) en Zeuthen. + +Se requieren tres clases de telescopios para cubrir todo el rango de energía del CTAO, desde 20 GeV hasta 300 TeV: [el Large-Sized Telescope (LST)](https://www.ctao.org/emission-to-discovery/telescopes/lst/), el [Medium-Sized Telescope (MST)](https://www.ctao.org/emission-to-discovery/telescopes/mst/) y el [Small-Sized Telescope (SST)](https://www.ctao.org/emission-to-discovery/telescopes/sst/). El proyecto para construir CTAO está muy avanzado: existen prototipos de trabajo para todos los diseños de telescopios propuestos y se ha llevado a cabo un trabajo significativo de caracterización y diseño del sitio. Además, en octubre de 2018, se inauguró el prototipo Large-Sized Telescope, el LST-1, en CTAO-Norte, y actualmente se encuentra en proceso de puesta en servicio. El Observatorio se beneficia de una configuración modular: si bien se espera que finalmente incluya hasta 118 telescopios repartidos entre ambos sitios de telescopios, durante la primera fase de construcción se construirá una instalación parcial con más de 60 telescopios, lo que ya será una mejora excepcional en comparación a las infraestructuras actuales. Esta configuración incluye 4 LST y 9 MST para el conjunto del hemisferio norte y 14 MST y 37 SST para el hemisferio sur. La [definición de esta configuración](https://www.ctao.org/for-scientists/performance/) es el resultado de un minucioso proceso de optimización de las capacidades científicas de cada conjunto, lo que implica la especialización del emplazamiento norte en fuentes extragalácticas (rango de energía del CTAO bajo-medio) y el del sur en objetos galácticos (rango de energía del CTAO medio-alto). + +La preparación del diseño e implementación del CTAO está gestionada por CTAO gGmbH, entidad legal interina hasta que se establezca la entidad final como CTAO ERIC (Consorcio Europeo de Infraestructuras de Investigación), a cargo de la construcción y operación del Observatorio.

The existing infrastructures and facilities, and ESO’s long-lasting experience spearheading international astronomical projects in Chile, will all support the construction and operation of the new telescope array. ESO will operate the facility on behalf of the CTA Observatory and its Members. + +Current gamma-ray telescope arrays only consist of a handful of individual telescopes, but CTA — with its larger collecting area and wider sky coverage — will be the largest and most sensitive array of gamma-ray telescopes in the world, with unprecedented accuracy and 10 times more sensitive than existing instruments. + +Although the Earth’s atmosphere prevents gamma rays from reaching the surface, CTA’s mirrors and high-speed cameras will capture the short-lived flashes of eerie blue Cherenkov radiation produced when gamma rays interact with the atmosphere. By detecting this Cherenkov light, scientists will be able to trace the gamma ray back to its cosmic source.[/vc_column_text][vc_column_text] + +On 19 December 2018, Ferrini met with ESO’s Director General, Xavier Barcons, at the ESO offices in Santiago, Chile.

One of the foundations of the movement is that equality is fundamental to developing a healthy and productive environment to achieve social and scientific goals. However, despite the global efforts, there is still a lot of work to do. According to a study in 14 countries around the world presented by the UN, the probabilities of graduating with a Bachelor’s degree, Master’s degree or Doctorate degree in science are 18%, 8% or 2%, respectively, for female students against the 37%, 18% and 6% for male students [1]. Worldwide, women represent less than 30% of the total researchers [2]. + +These disparities persist in many different ways, one of which is called the “Leaky Pipeline.” This metaphor is used to illustrate how women enter the field at a higher percentage (sometimes exceeding men) but drop off as they move “up the ladder” to the higher stages of their career.

In the past decades, astrophysicists have been able to grasp several aspects of the functioning of these structures, thought to be launched by rotating magnetic fields close to the horizon of supermassive black holes. + +One of the most basic questions about jets is the one related to the nature of the radiating particles and the mechanisms at the base of the emission that we observe. While there is wide consensus on the fact that the radiation at the lowest frequencies (from radio up to soft X-rays) originates from electrons spiraling in the jet magnetic field (synchrotron radiation), more debated is the source of the photons detected as gamma rays. It is often assumed that the main emitters are electrons (leptons), producing gamma rays through the scattering of low-energy photons (inverse Compton emission). On the other hand, there are also several supporters of the alternative idea, the hadronic scenario, which envisions gamma rays as the by-product of reactions initiated by protons (or other nuclei) smashing into other nuclei or low-energy photons. The idea is quite appealing: the discovery of the presence of protons accelerated to the highest energies could also open the way to the identification of the still mysterious sources of the ultra-high-energy cosmic rays that bombard the Earth’s atmosphere. + +The difference between the properties of the radiation deriving from the two processes is quite minute. Only with very accurate measurements of the spectrum at TeV energies can one hope to firmly identify the underlying emitters (see below figure). Current Cherenkov telescopes do not have the sensitivity required for this difficult task. CTA, with its improved sensitivity, will be able to provide a definite answer to the question.

Now, the world-wide science community is looking forward to seeing results from CTA, the next generation ground-based gamma-ray detector, which is anticipated to provide a wealth of new information with unprecedented precision. + +Especially important for multi-messenger astronomy was the detection of gamma rays associated with a high-energy neutrino, IceCube-170922A, attributed to the Blazar TXS 0506+056 [1]. More than twenty instruments reacted to the neutrino alert and contributed to disclosing its astrophysical nature (see Fig. 1). + +![](/uploads/fig2-1.png) + +*Figure 1: Timeline of the multi-messenger Astronomer’s Telegram announcing some of the follow-up observations triggered by the IceCube-170922A event alert. Credit: IceCube Collaboration* + +The event was a breakthrough in multi-messenger synergy, combining information from different types of particles and waves to reveal the physical processes behind extreme astrophysical phenomena. High-energy neutrinos with energies larger than a few GeV are the products of protons or ions (hadronic cosmic rays) interacting with surrounding matter or radiation. A fraction of those cosmic rays may escape their astrophysical sources, but, since they are charged particles, they will be deflected during their propagation by intergalactic magnetic fields. Neutrinos, as neutral particles, keep memory of their source’s direction and, hence, their detection have become crucial to unraveling the origin of this type of cosmic ray. + +Nevertheless, capturing cosmic neutrinos is a difficult task. Large-scale detectors are needed to detect these weakly interacting particles, like the current [IceCube](https://icecube.wisc.edu/) at the South Pole, [ANTARES](http://antares.in2p3.fr) in the Mediterranean Sea and Baikal at Lake Baikal. Despite being instrumented at important depths with enormous volume, such instruments are challenged by weak signals and strong foregrounds induced by cosmic-ray interactions in the Earth’s atmosphere. Still, in 2013, the discovery of a diffuse flux of high-energy neutrinos was reported by the IceCube Collaboration [2]. This result is a clue towards finding the long-sought sources of hadronic cosmic rays, but long-exposure neutrino sky maps do not yet show significant indications of individual sources. So far, only the object class of a single high-energy neutrino source, the aforementioned Blazar TXS 0506+056, was identified. Thus, the origin of the bulk of cosmic neutrinos remains a mystery. + +The chances to capture the faint source of neutrinos can be increased by observing transient phenomena, simultaneously with other high-energy messengers like gamma rays. Since gamma rays and neutrinos can be produced in connection to each other at the same source, by catching the electromagnetic signals emitted quasi-simultaneous to neutrinos, the time- and space-coincidence of both messengers significantly removes the cosmic-ray atmospheric foregrounds that challenge the neutrino detectors. Gamma rays, like neutrinos, do not have a charge so their trajectory can be traced back to their origin, as well. They are much easier to detect, allowing gamma-ray detectors to provide more accurate information about the source’s location in the sky, but they are produced by different physical processes involving different types of particles. In this regard, neutrinos serve as smoking guns for high-energy hadronic cosmic rays. Their combined study, also along with other wavelengths, provide a unique view on high-energy sources, as happened in the case of the IceCube-170922A event [see e.g. 2]. + +The CTA Key Science Projects include a dedicated program to investigate neutrino transients to expand our knowledge in this field. Along with current and future neutrino observatories (such as the next generation [IceCube-Gen2](https://icecube.wisc.edu/science/beyond) and Baikal-GVD), CTA’s detection of very high-energy gamma rays associated with cosmic neutrinos will play a key role in unveiling possibly new neutrino-emitting sources, as well as helping to reveal the origin of ultra-high-energy cosmic rays. With a sensitivity that is about 10 times better than any existing gamma-ray instrument, reaching energies up to 300 TeV, CTA will address the origin of TeV-PeV cosmic neutrinos beyond the edge of the known electromagnetic spectrum. This will open the window to the study of different transient events, like tidal disruption events, in which a star is swallowed by a supermassive black hole, low-luminosity gamma-ray bursts or supernovae with strong interactions with circumstellar material. The program is tailored to address transient phenomena and respond to alerts issued by neutrino observatories, such as IceCube, in a modern version of the so-called Neutrino Triggered Target of Opportunity (NToO) program. + +CTA will also employ a real-time analysis to search for unexpected gamma-ray signals, which will allow CTA to generate and release alerts to other observatories to avoid missing any interesting cosmic event (Fig. 2). This will strengthen the multi-messenger cooperation in the upcoming years and ensures new discoveries that will increase the understanding of our Cosmos and the physical processes therein. + +![](/uploads/Screen-Shot-2017-07-07-at-13.09.02-1600x753.png) + +*Figure 2: CTA dataflow from the data acquisition on-site, including the real-time analysis and alerts between observatories.

What are the main changes brought by the new legal entity? + +The establishment of the CTAO as an ERIC comes after many years of work of many enthusiastic people, who recognised the scientific value and opportunity of investing in this rising observatory. The ERIC label adds commitment and credibility to the project, also at the highest level by engaging the ministries and the European Commission, which is essential for its long-term success. + +### Based on your experience, what are the biggest opportunities of operating as an ERIC? + +There are now 30 operational ERICs in all fields of science, three in astronomy: JIVE, LOFAR, and now the CTAO. Being a legal entity under the ERIC regulation gives stability but also great flexibility, allowing us to define policies and procedures that are well suited to the Observatory’s mission. + +### How do you see the evolution of international collaboration under this new context? + +With the ERIC, Europe has a great tool to attract the establishment of global research infrastructures. The CTAO ERIC is a good example since partners around the world support the construction and operation of this astronomical observatory with headquarters in Italy, data management centre in Germany, and telescope sites in Spain (Canary Islands) and Chile. There are, however, still some challenges to smoothly incorporate non-EU partners, which have been identified and are being addressed by the European Commission. Hopefully, soon, it will become a much easier process, not just for our benefit but for the European and international research communities. + +### Following the creation of the CTAO ERIC, we now celebrate the establishment of its Council. Can you explain what this achievement means for the Observatory and, personally, for you to be Chair? + +The Council of the CTAO ERIC is the body where the investors of the research infrastructure meet, and make the most important decisions on strategies but also operations. There are two delegates per ERIC member, but also representatives from strategic partners, observers, and third-party organisations. This ensures that all opinions are heard, and all interests are considered. Being the first chair is an honor but also a great responsibility — I aim to build trust, so consensus is achieved on the essential issues. + +### What are the key first steps the CTAO ERIC Council will focus on in the coming months? + +In the coming months, we expect to move all assets and activities from the CTAO gGmbH (former legal entity of the Observatory) to the CTAO ERIC, so the whole project runs under one umbrella. The team at the CTAO Central Organisation will also transition and continue to grow as the construction of some of the telescopes will advance at a rapid pace. While this is ongoing, we also need to start planning for operations and early science. There is a lot to do! + +### The CTAO ERIC was initially formed with the commitment of 11 countries and one intergovernmental organisation, but there is an increasing international interest in the CTAO. Can we already anticipate participation of new countries at governmental level? + +The support of the founding countries and ESO is a demonstration of the interest in the CTAO, which extends to other partners around the world. We are already in talks with additional countries so we are certain that our membership will continue to grow. There are many ways to engage in the project, to serve different communities and their circumstances, ensuring that we are as inclusive as possible. + +### As the CTAO is now entering fully into the construction phase, what are the key priorities from a strategic perspective? + +Our priority is to ensure the maximum quality in the construction of the telescopes and data centres, while respecting the timing and availability of resources in an always complex and quickly changing scenario. Not less important, to attract more partners and funding needed for the CTAO ERIC to be a sustainable organisation for many years to come. + +### Looking toward the future, what long-term impact do you hope the CTAO will have on astrophysics and beyond? + +We are building the most advanced and powerful instrument to study gamma rays in the Universe. I hope its discoveries will expand and change our understanding of the most energetic processes in astrophysics. + +### Finally, what message would you share with the global technical and scientific communities that are eagerly awaiting to explore the extreme Universe with the CTAO? + +Scientists are eager to receive data from the CTAO ERIC which will certainly bring new discoveries. We share this enthusiasm and will work hard to complete the construction of the facilities and reach early science as soon as possible. There are great challenges in this project, which we can only overcome with the involvement of the best technical and scientific experts, and the CTAO is fortunate to have such a strong professional community. Soon, the global scientific community will have an unprecedented tool to explore the extreme Universe, opening new frontiers of the Cosmos.

In this case, OP 313 is located at a redshift of 0.997 or ~8 billion light years away, making it the most distant AGN and the second most distant source ever detected at very high energies. + +The more distant the source, the more difficult it is to observe at very high energies due to the so-called Extragalactic Background Light or EBL. The EBL is the collective light emitted by all objects outside the Milky Way that expands across multiple wavelengths, from visible, infrared and ultraviolet. The EBL interacts with very high-energy gamma rays, attenuating their flux and, thus, making their observation challenging. The characteristics of the LST-1, with an optimized sensitivity for the CTAO’s low energy range, between 20 and 150 GeV, where gamma rays are less affected by the EBL, enabled the LST Collaboration to extend the study of this source to tens of GeV for the first time. + +The LST Collaboration will continue to observe this source with the LST-1 to expand the dataset and, thus, obtain a more precise analysis that allows scientists to improve their understanding of the EBL, study the magnetic fields within this type of source or delve into fundamental intergalactic physics. + +### About the LST + +The Large-Sized Telescope (LST) is one of three types of telescope that will be built to cover CTAO’s full energy range (20 GeV to 300 TeV). The approved Alpha Configuration of the CTAO includes four LSTs arranged at the centre of the northern hemisphere array. An enhancement plan of such layout includes also two LSTs in the southern array, which are funded. These telescopes are optimized to cover the low-energy sensitivity between 20 and 150 GeV. Each LST is a giant 23 metre diameter telescope with a mirror area of about 400 square metres and a fine pixelized camera made of 1855 light sensors capable of detecting individual photons with high efficiency. Although the LST stands 45 metres tall and weighs around 100 tonnes, it is extremely nimble, with the ability to reposition within 20 seconds to capture brief, low-energy gamma-ray signals. Both the fast repositioning speed and the low energy threshold provided by the LSTs are critical for CTAO’s studies of transient gamma-ray sources in our own Galaxy and for the study of active galactic nuclei and gamma-ray bursts at high redshift. The prototype of the LST, the LST-1, is located at CTAO-North and is currently under commissioning. It is expected to become the first CTAO telescope once its commissioning is complete and it has been officially accepted. + +### About the LST Collaboration + +The LST Collaboration is made up of over 400 scientists and engineers from 67 different institutions across twelve countries.

The CTAO’s unparalleled accuracy and broad energy range (20 GeV- 300 TeV) will provide novel insights into the most extreme and powerful events in the Cosmos, addressing questions in and beyond astrophysics falling under three major themes: Understanding the origin and role of relativistic cosmic particles, probing extreme environments (such as black holes and neutron stars) and exploring frontiers in physics (such as the nature of dark matter). To do so, the CTAO will use three types of telescopes: the Large-Sized Telescopes (LST), the Medium-Sized Telescopes (MST) and the Small-Sized Telescopes (SST). More than 60 telescopes will be distributed between two telescope array sites: CTAO-North in the northern hemisphere at the Instituto de Astrofísica de Canarias’s (IAC’s) Roque de los Muchachos Observatory on La Palma (Spain), and CTAO-South in the southern hemisphere near the European Southern Observatory’s (ESO’s) Paranal Observatory in the Atacama Desert (Chile). The headquarters of the CTAO is hosted by the Istituto Nazionale di Astrofisica (INAF) in Bologna (Italy), and the Science Data Management Centre (SDMC) is hosted by the Deutsches Elektronen-Synchrotron (DESY) in Zeuthen (Germany). The CTAO will also be the first observatory of its kind to be open to the worldwide scientific communities as a resource for data from unique, high-energy astronomical observations. + +The CTAO Central Organisation works in close cooperation with partners from around the world toward the development of the Observatory. Major partners include In-Kind Contribution teams, such as the Telescope teams that are developing essential hardware and software, in addition to the CTAC, an international group of researchers who have provided scientific guidance since the project’s inception. + +The CTAO was promoted to a “Landmark” on the [European Forum on Research Infrastructure (ESFRI) Roadmap](https://www.cta-observatory.org/cta-promoted-to-landmark-status-on-2018-esfri-roadmap/) [2018](https://www.cta-observatory.org/cta-promoted-to-landmark-status-on-2018-esfri-roadmap/) , and was ranked as the main priority among the new ground-based infrastructures in the [ASTRONET Roadmap 2022-2035](https://www.cta-observatory.org/strategic-plan-for-european-astronomy-ranks-ctao-as-priority/). + +### Contact + +Prof. Masahiro Teshima + +LST Principle Investigator (PI) + +[mteshima@icrr.u-tokyo.ac.jp](mailto:mteshima@icrr.u-tokyo.ac.jp) + +(English, Japanese) + +LST Outreach Team + +[lst-outreach@cta-observatory.org](mailto:lst-outreach@cta-observatory.org) + +(English) + +Dr. Alba Fernández-Barral + +CTAO Chief Communication Officer + +[alba.fernandezbarral@cta-observatory.org](mailto:alba.fernandezbarral@cta-observatory.org) + ++39-051-6357-270 + +(English, Spanish and Italian) diff --git a/src/content/news/lst-1_inauguration.md b/src/content/news/lst-1_inauguration.md new file mode 100644 index 0000000..0b6b3b4 --- /dev/null +++ b/src/content/news/lst-1_inauguration.md @@ -0,0 +1,69 @@ +--- +title: "LST-1 Inauguration: 10 October 2018, La Palma" +description: "On Wednesday, 10 October 2018, more than 200 guests from around the world will gather on the northern array site of the Cherenkov Telescope Array (CTA) to celebrate the inauguration of the first prototype Large-Sized Telescope (LST).

The telescope, named LST-1, is intended to become the first of four LSTs on the CTA-North site, which is located on the existing site of the Instituto de Astrofisica de Canarias’ (IAC’s) [Observatorio del Roque de los Muchachos](http://www.iac.es/eno.php?op1=2&lang=en) located in the municipality of [Villa de Garafia](http://www.garafia.es/) on the island of La Palma. The plan for the site also includes 15 Medium-Sized Telescopes (MSTs). + +It was on 9 October 2015 that the first stone-laying ceremony took place for the LST-1. After the telescope foundation was completed in January 2017, the team moved swiftly and steadily toward its next major milestones: installation of the center pin and rails (September 2017), mounting of the dish (December 2017). In 2018, the LST-1 structure was completed in February and the camera support structure was installed in June. The final step, the camera installation, was completed on 25 September 2018. + +The LST team consists of more than 200 scientists from ten countries: Brazil, Croatia, France, Germany, India, Italy, Japan, Poland, Spain and Sweden. In this truly international effort, the design and management leadership was shared among LAPP, Annecy, France; Max Planck Institute for Physics, Munich, Germany; INFN, Italy; ICRR, University of Tokyo, Japan; and IFAE, Barcelona and CIEMAT, Madrid, Spain. + +In addition to the LST, two other classes of telescope are required to cover CTA’s full energy range from 20 gigaelectronvolt (GeV) to 300 teraelectronvolt (TeV): Medium-Sized Telescopes and Small-Sized Telescopes. Because gamma rays with low energies produce a small amount of Cherenkov light, telescopes with large mirrors are required to capture the images. Four LSTs will be arranged at the centre of both the northern and the southern hemisphere arrays of the Observatory to cover the low-energy sensitivity of CTA between 20 and 150 GeV. + +The LST has a 23-metre diameter parabolic reflective surface, which is supported by a tubular structure made of reinforced carbon fibre and steel tubes. A reflective surface of 400 m2 collects and focuses the Cherenkov light into the camera, where photomultiplier tubes convert the light in electrical signals that can be processed by dedicated electronics. Although the LST-1 stands 45 metres tall and weighs around 100 tonnes, it is extremely nimble, with the ability to re-position within 20 seconds to capture brief, low-energy gamma-ray signals. + +The LSTs will expand the science reach to cosmological distances and fainter sources with soft energy spectra. Both the re-positioning speed and the low energy threshold provided by the LSTs are critical for CTA studies of transient gamma-ray sources in our own Galaxy and for the study of active galactic nuclei and gamma-ray bursts at high redshift. The prototype is foreseen to become the first LST telescope of CTA, and, in fact, the first telescope on a CTA site, to be operated by the CTA Observatory (CTAO). As any other technical delivery in the large, multinational CTA project, the LST-1 will need to undergo a critical design review to verify that the design complies with CTA science goals, operational needs, safety standards, etc. before it is formally accepted by CTAO. + +Go to the LST-1 Inauguration webpage (https://www.cta-observatory.org/lst-1_inauguration) on the CTA website for more information in other languages and links to supporting materials, images and video. + +**Notes for Editors:** + +CTA (www.cta-observatory.org) is a global initiative to build the world’s largest and most sensitive high-energy gamma-ray observatory with about 120 telescopes split between two sites: one in the northern hemisphere at the Roque de los Muchachos astronomical observatory in the municipality of Villa de Garafia on the island of La Palma, Spain, and the other in the southern hemisphere near the existing European Southern Observatory site at Paranal, Chile. More than 1,400 scientists and engineers from 31 countries are engaged in the scientific and technical development of CTA. The planning for the construction of the Observatory is managed by the CTAO gGmbH, which is governed by Shareholders and Associate Members from a growing number of countries. + +CTA will be the foremost global observatory for very high-energy gamma-ray astronomy over the next decade and beyond and will be the first ground-based gamma-ray astronomy observatory open to the world-wide astronomical and particle physics communities. The scientific potential of CTA is extremely broad: from understanding the role of relativistic cosmic particles to the search for dark matter. With its ability to cover an enormous range in photon energy from 20 GeV to 300 TeV, CTA will improve on all aspects of performance with respect to current instruments.

The paper focuses on a multi-wavelength study of the unidentified ultra-high-energy gamma-ray source known as LHAASO J2108+5157. For the analysis, the LST Collaboration used 49 hours of data obtained with the LST-1, the prototype of the Large-Sized Telescope (LST) currently under commissioning at CTAO-North on La Palma (Spain). While the analysis did not result in any significant detection, the multi-wavelength approach, combining data from the LST-1 and other instruments, allowed the team to set strict upper limits on the source’s emission that help shed light on its nature. + +In 2021, several new ultra-high-energy (UHE) gamma-ray sources, capable of emitting gamma rays above petaelectronvolts (PeV; thousands of trillions the energy of visible light), were discovered in the Milky Way by the Large High Altitude Air Shower Observatory (LHAASO). This represented a step forward in the search for PeVatrons, enigmatic sources in our Galaxy that can accelerate cosmic rays up to PeV energies and give rise to gamma rays at the highest energies. Under this new context, the LST Collaboration used the LST-1 to observe the source LHAASO J2108+5157, one of the PeVatrons seen by LHAASO without a known TeV counterpart, from June to September 2021 for a total of 49 nights. + +“When the LHAASO Collaboration discovered that our Galaxy hosted multiple PeVatrons, it came as a huge surprise – we immediately decided to explore these sources and observed one of them with the LST-1 to find a counterpart at lower energies,” explains Jakub Jurysek, researcher at the institute of Physics of the Czech Academy of Science (FZU) and University of Geneva, and principal investigator of this study. “We could not confirm a detection, but we could set strong limits on the emission of the source and, thus, improve the understanding of this object’s nature compared to the scenario originally assumed by the scientific community.” + +![](/uploads/SED_LST1_LHAASOJ21085157.png) + +Emission of the source at different energy ranges. The blue arrows represent the upper limits on the source’s emission at TeV energies as established by the LST-1. The orange points correspond to the higher-energy emission detected by LHAASO in 2021. The green and blue bands correspond to the best fit of the data assuming a source’s emission described by a power law and a power law with cut off scenario, respectively. Credit: LST Collaboration + +Even though a confirmed detection of the very high-energy emission would require deeper observations, the LST-1 data, complemented by a multi-wavelength study using public data from the XMM-Newton and Fermi-LAT satellites, already provide important information about the source. Contrary to previous assumptions, the low magnetic field and spectral properties obtained by the LST Collaboration are compatible with the hypothesis that the source is a Pulsar Wind Nebula or a TeV halo that can accelerate electrons to relativistic energies. Nonetheless, this scenario is challenged by the lack of a known pulsar in the surroundings. Another hypothesis that could explain this unidentified UHE gamma-ray source is that its emission is caused by the interaction between the gas of nearby molecular clouds and protons accelerated in the past by a Supernova Remnant, a leftover from the death of a massive star. + +Despite the lack of a significant detection, the results show the LST-1’s extraordinary level of performance and its capability to provide robust observational constraints to test theoretical frameworks, which foretells the excellent results that will be obtained once the full CTAO array is operational. diff --git a/src/content/news/lst-collaboration-publishes-lst1-performance-paper.md b/src/content/news/lst-collaboration-publishes-lst1-performance-paper.md new file mode 100644 index 0000000..d5f4313 --- /dev/null +++ b/src/content/news/lst-collaboration-publishes-lst1-performance-paper.md @@ -0,0 +1,23 @@ +--- +title: "The LST Collaboration Publishes the LST-1 Performance Paper" +description: "On 14 July 2023, the performance paper of the LST-1 was accepted for publication in the Astrophysical Journal (ApJ)." +date: 2023-07-26 +category: news +author: CTAO +cover: /uploads/48629242378_5cb352496e_o-768x512.jpg +draft: false +--- + +On 14 July, the performance paper of the LST-1, the prototype of the Large-Sized Telescope (LST) currently under commissioning at CTAO-North on La Palma (Spain), was accepted for publication in the Astrophysical Journal (ApJ). The study, carried out by the LST Collaboration, describes the telescope’s capabilities, including key parameters such as its sensitivity and its angular and energy resolution, and validates the simulations required for data analysis. This paper is fundamental to the upcoming science publications as it sets a performance baseline for the instrument and ensures its reliability. + +“In simple words, a performance paper is a handbook for how the telescope works: it shows its capabilities and limitations,” explains Abelardo Moralejo, LST-1 Analysis Software Coordinator and author of the paper. “It allows us to evaluate potential systematic errors of the instrumentation that could affect the interpretation of data. Thus, a deep understanding of the telescope’s performance, towards which this paper is an important step, ensures that the scientific results with the LST-1 are reliable and reproducible.” + +In order to evaluate the LST-1’s performance, the LST Collaboration made use of a comprehensive data set from observations of the Crab Nebula spanning from November 2020 to March 2022. The Crab Nebula is the standard candle in very high-energy astronomy, a source whose luminosity is well-known and steady at those energies. Such observations allowed the team to also verify that the simulations needed during the scientific data analysis were correct. + +“Analyzing data from the Crab Nebula provides valuable insights into its emission behaviour and evolution with energy and time. By comparing the results to what we expect from the source as a standard candle, we can determine the instrument’s sensitivity and precision, and correct our simulations, if necessary,” says Rubén López-Coto, LST-1 Analysis Software Deputy Coordinator and author of the paper. “The study shows that the telescope not only performs exceptionally well overall, as expected, but it also narrows the gap with other instruments at lower energy levels, thanks to its proven low-energy threshold.” + +The low-energy threshold is a fundamental parameter of the LSTs, as these telescopes are responsible to cover the sensitivity of the CTAO at the lowest energies by capturing gamma rays down to 20 GeV. The performance study is complemented by observations of the Crab pulsar, the neutron star at the centre of the Crab Nebula. + +“Pulsars are very challenging sources to detect due to their weak signal,” says Masahiro Teshima, Principal Investigator of the LST Collaboration. “The LST-1 can detect the two pulses of the Crab pulsar in record time. This is not only an extraordinary result, but it also demonstrates the LST-1’s capabilities in detecting faint sources at low energies, as described in the paper.” + +This is the first performance paper of a telescope prototype on a CTAO site. While the LST-1’s observing capabilities as a single telescope are already remarkable, these results will only improve once more telescopes are built and begin to operate together, thus expanding our current understanding of the gamma-ray Universe. diff --git a/src/content/news/lst-dish-mounted.md b/src/content/news/lst-dish-mounted.md new file mode 100644 index 0000000..bbf722c --- /dev/null +++ b/src/content/news/lst-dish-mounted.md @@ -0,0 +1,15 @@ +--- +title: "The LST Prototype’s Dish is Mounted" +description: "The Large-Sized Telescope prototype reached a major milestone on 4 December 2017 when its dish was successfully mounted to its lower structure." +date: 2017-12-05 +category: news +author: CTAO +cover: /uploads/Foto-de-Javier-Herrera-Llorente-768x422.jpg +draft: false +--- + +On 4 December, The LST prototype, under construction at Roque de los Muchachos Observatory in La Palma, reached an important milestone when its 18-ton mirror dish, mostly made of reinforced carbon fiber tubes, was lifted to the lower structure successfully.

While detecting the strong and steady emission or outbursts of gamma-ray sources with Imaging Atmospheric Cherenkov Telescopes (IACTs) has become routine, pulsars are much more challenging to detect due to their weak signals and the typical dominance of the foreground gamma-ray signal from the surrounding nebulae.

LSTs arranged at the centre of both the northern and southern hemisphere arrays will cover the low-energy sensitivity between 20 and 150 GeV. Each LST is a giant 23 metre diameter telescope with a mirror area of about 400 square metres and a fine pixelized camera made of 1855 light sensors capable of detecting individual photons with high efficiency. Although the LST stands 45 metres tall and weighs around 100 tonnes, it is extremely nimble, with the ability to re-position within 20 seconds to capture brief, low-energy gamma-ray signals. Both the fast re-positioning speed and the low energy threshold provided by the LSTs are critical for CTA’s studies of transient gamma-ray sources in our own Galaxy and for the study of active galactic nuclei and gamma-ray bursts at high redshift. + +The LST collaboration, consists of more than 200 scientists from 11 countries: Brazil, Bulgaria, Croatia, France, Germany, India, Italy, Japan, Poland, Spain and Switzerland.

CTA will be the foremost global observatory for very high-energy gamma-ray astronomy over the next decade and beyond and will be the first ground-based gamma-ray astronomy observatory open to the world-wide astronomical and particle physics communities. CTA will address some of the greatest mysteries in astrophysics, detecting gamma rays with an unprecedented sensitivity and expanding the cosmic source catalogue tenfold. CTA is a unique, ambitious large-scale infrastructure that will expand observations up to a region of the spectrum that has never been seen, opening an entirely new window to our Universe. The CTAO gGmbH serves to prepare the design and implementation of the CTA Observatory. The CTAO works in close cooperation with the CTA Consortium composed of 1500+ members from 31 countries, which is responsible for directing the science goals of the Observatory and is involved in the design and supply of instrumentation.

More than 1,400 scientists and engineers from [31 countries](https://www.cta-observatory.org/about/cta-consortium/) across five continents and more than 200 research institutes are participating in the CTA project.  Hosted by CTA Consortium members the [University of Geneva](https://www.unige.ch/),  [ETH Zurich](https://www.ethz.ch/en.html) and the [University of Zurich](https://www.uzh.ch/en.html), as well as the [Swiss National Computing Centre (CSCS)](https://www.cscs.ch/), the event is expected to attract hundreds of scientists from around the world. CTA is a global initiative to build the world’s largest and most sensitive high-energy gamma-ray observatory with 118 telescopes split between two sites: one in the northern hemisphere on the island of La Palma, Spain, and the other in the southern hemisphere near Paranal, Chile. CTA will be the foremost global observatory for very high-energy gamma-ray astronomy over the next decade and beyond and will be the first ground-based gamma-ray astronomy observatory open to the world-wide astronomical and particle physics communities. CTA will probe cosmic particle accelerators reaching energies inaccessible to man-made accelerators.

CTA will also search for annihilating dark matter particles and deviations from Einstein’s theory of special relativity. + +### CTA and Switzerland + +After more than a decade of design studies of the Cherenkov Telescope Array led by a Consortium of scientists, the CTAO gGmbH was established in 2014 to direct the design and implementation of CTA with the University of Zurich, representing Switzerland, as a founding member. Today, the CTAO is composed of [shareholders](https://www.cta-observatory.org/about/governance/) from 11 countries, one intergovernmental organisation (the European Southern Observatory), as well as associate members. Activities related to the study of the high-energy Universe started in the 1990s at the University of Geneva and at ETH Zurich. Swiss scientists have been actively pursuing the development of CTA since 2007, in particular in the construction of novel solid-state Cherenkov cameras (pioneered by ETH Zurich and developed at UniGe), a [Small-Sized Telescope](https://www.cta-observatory.org/project/technology/sst/) protoype (UniGe), mirror actuators (pioneered at ETH Zurich and continued at UZH), camera housing and electronics (UZH), and in data processing activities (UniGe and ETH Zurich) and the study of the high-energy Universe (UniGe, ETH Zurich, UZH), permitting Swiss scientists to participate in the core of CTA science and contribute to the success of CTA as an open observatory. From 2016 to 2017 the CTAO was managed by Prof. U. Straumann (UZH) and became a landmark on the roadmap of the ESFRI (European Strategy Forum on Research Infrastructures). CTA was also identified on the Swiss roadmap for research infrastructure in 2015 and 2019, and the Swiss parliament opened a credit line for CTA in 2016. Lugano was chosen as the site of the next CTA consortium meeting to showcase Switzerland’s world-class capabilities in the handling of large amounts of scientific computation and data. + +### About the Event + +This event will feature presentations from the chairs and members of the Astroparticle Physics European Consortium (APPEC), the Swiss Institute of Particle Physics (CHIPP), the State Secretariat for Education Research and Innovation (SERI), Polythechnical schools and from CTA. + +### Please RSVP and ****direct all questions to: + +Roland Walter + ++41223792128 + +[lugano2019@unige.ch](mailto:lugano2019@unige.ch) diff --git a/src/content/news/major-telescope-operations-milestone-with-acada-integration.md b/src/content/news/major-telescope-operations-milestone-with-acada-integration.md new file mode 100644 index 0000000..16dc404 --- /dev/null +++ b/src/content/news/major-telescope-operations-milestone-with-acada-integration.md @@ -0,0 +1,27 @@ +--- +title: "Major Telescope Operations Milestone Achieved with ACADA Software Integration" +description: "In September and October, two teams of scientists and engineers traveled to the CTAO-North site in La Palma, Spain, to conduct pivotal tests of ACADA system on the LST-1." +date: 2023-12-20 +category: news +author: CTAO +cover: /uploads/LST1_3-1600x900.png +draft: false +--- + +Over two separate weeks in September and October, two teams of scientists and engineers traveled to the CTAO-North site in La Palma, Spain, to conduct pivotal tests of the Array Control and Data Acquisition (ACADA) system on the LST-1, the prototype of the Large-Sized Telescope. ACADA will be the central software in charge of operating the CTAO’s two arrays of telescopes in La Palma and in Chile. These tests are instrumental in assessing the software’s functionality on an individual telescope, a prerequisite for extending its application to a broader range. After almost two years of preparations by the ACADA team in cooperation with the LST Collaboration, the integration campaign and its successful outcome marked a significant milestone for the development of ACADA. + +You are currently viewing a placeholder content from **Default**. To access the actual content, click the button below. Please note that doing so will share data with third-party providers. + +Over several months, the ACADA integration and testing campaign was orchestrated with a specific objective: to validate the seamless integration of the software with the LST-1. The two testing missions focused on establishing flawless bidirectional communication between ACADA and the telescope, enabling functions such as remote commands for the LST-1’s movement or real-time data analysis. Additionally, the system was tested under unpredictable scenarios like simulating alerts from a cosmic source’s transient activity, which requires a swift response from the joint ACADA/LST-1 system. + +Igor Oya, ACADA Coordinator, explained the rationale behind the separate testing missions: “The initial phase concentrated on individual tasks, such as ACADA’s ability to make the LST-1 move, monitor its status or comprehend the data coming from the telescope. The second phase was an ‘end-to-end’ test to demonstrate that the system could perform standard operations for a full night of observation.” + +Results from the campaign yielded positive outcomes that confirm the software’s ability to execute critical tasks. On the first day of observations, the team successfully detected the Crab Nebula, which is the “standard candle” for instruments in gamma-ray astronomy. + +“This is a very important step for everyone involved in the CTAO,” says Daniel Mazin, LST-1 Programme Manager. “It is a big step that the ACADA software development is meeting the real-life, the telescope here in La Palma, so we can see how the different software parts work together to operate this telescope and take scientific data.” + +While celebrating these accomplishments, the teams also identified areas for optimization and potential enhancements. “We will revisit and rectify minor issues and explore improvements,” says Bernhard López, ACADA Deputy Coordinator. “Next year, we will develop and test updated versions of ACADA, collaborating with different teams to create a robust system capable of managing not only one telescope, but a full array of telescopes simultaneously.” + +The testing campaign exemplified the collaborative efforts between the LST Collaboration and the ACADA team, which is made up of around 60 people from the CTAO and its partners from nine institutes from six countries: Centrum Astronomicznego im. Mikołaja Kopernika (CAMK), Deutsches Elektronen-Synchrotron (DESY), Ciències de l’Espai/ Consejo Superior de Investigaciones Científicas (ICE/CSIC), Istituto Nazionale di Astrofisica (INAF), Laboratoire d’Annecy de Physique des Particules (LAPP), Max-Planck-Institut für Kernphysik (MPIK), University of Geneva, University of Perugia and University of Potsdam. + +Tune into the CTAO’s social media channels in 2024 for a series of videos that will take a closer look at the importance of ACADA to the Observatory and the individuals driving its success! diff --git a/src/content/news/managing-director-planning-funding-and-paperwork.md b/src/content/news/managing-director-planning-funding-and-paperwork.md new file mode 100644 index 0000000..3ed0b7d --- /dev/null +++ b/src/content/news/managing-director-planning-funding-and-paperwork.md @@ -0,0 +1,24 @@ +--- +title: "Update from the Managing Director: Planning, Funding and Paperwork" +description: "While the summer is traditionally characterized as a period of slower rhythms and some relaxation, the CTAO management took advantage of this lull in activity to continue the development of the concepts and documents that will drive a…" +date: 2019-10-09 +category: news +author: CTAO +draft: false +--- + +Originally published in the [October 2019 issue of the CTA Newsletter](https://mailchi.mp/12cb6698d185/cta-newsletter-october2019-english). + +*By: Federico Ferrini, CTAO Managing Director* + +It was Wernher von Braun who said, “Our two greatest problems are gravity and paperwork.

Among the many documents that were on the table were: the Cost Book (finalising the version that will be sent to an external panel); the Medium-Term Plan (conceiving its structure and starting to organise the content of chapters); the Management Plan (advancing its redaction); the Business Plan (modifications to reflect the current project conditions); and the Science Data Management Centre Hosting Agreement (negotiations with DESY concluded and awaiting final approvals for signature). + +Additionally, in September, the CTAO shareholders ratified their strong support of the CTA project by finalising their contributions at an extraordinary meeting of the CTAO Council. The final 2020 budget to prepare the design and implementation of the observatory is being considered (with recommendations from the Administrative and Finance Committee) for approval at the November Council meeting. The Council also approved the panel for the Cost Book analysis and validation and expressed its consensus on the Phase I objective for the CTAO-ERIC: to construct the threshold configuration of the observatory (with the promised funding of about 310 MEuro). + +It is my intention to conclude all the matters posed on the table by the end of November (although approval by our governing bodies may arrive later), including implementing an efficient, transparent and fully integrated CTAO on the CTA-North site in La Palma. And, in the not-so-distant future, we will target the end of March 2020 for the ERIC Step 2 Application, organise the gGmbH to ERIC transition, advance the risk management plan, promote a sound proposal for the Medium-Sized Telescope harmonisation, recruit more staff and revise the documentation system. + +Perhaps it may be too much (work and paperwork), but, clearly, we are at a turning point of the CTA project, and I am grateful to the CTAO staff and our CTA Consortium partners in their continuing efforts to realise this program. + +Finally, we are in the beginning stages of a very promising collaboration – the CTAO recently met with the Square Kilometre Array (SKA) Organisation and discussed possible joint activities. There is more to come on this topic, but I am confident that in the next few months we will announce significative progress.

For the first time in history, the CTA Consortium meeting was organised as a full online meeting. The meeting was expanded to almost two weeks, from 13 to 22 May, so that sessions were limited to a few hours per day. In total, about 500 Consortium members registered for the online meeting with a peak attendance of about 270 people for a single session (see screen shot below that was taken during one of the plenary sessions). + +As usual, the meeting started with parallel sessions during the first few days, followed by plenary sessions and closed by a Consortium Board meeting on the last day. While feedback on the online meeting format was very positive, people regretted the lack of informal gatherings during the coffee breaks and evenings that usually foster the interactions between colleagues. All plenary sessions were recorded, providing those who could not connect the possibility to replay the meeting. This is particularly useful for a world-wide Consortium such as CTA, with members distributed over many different time zones. + +On the technical side, a highlight of the meeting was the announcement of the detection of TeV emission from the Crab nebula with the Schwarzschild-Couder Telescope prototype (pSCT). The pSCT is a prototype of a mid-sized telescope that is being developed by an international team under the leadership of our U.S. colleagues. The detection of the Crab nebula presents an important milestone for the project and demonstrates the feasibility of an innovative concept that has the potential to significantly improve the angular resolution of CTA. Other highlights of the meeting were the status reports of the Medium-Sized Telescope (MST) and Small-Sized Telescope (SST) sub-consortia that have organised to provide the MSTs and SSTs for CTA. Together with the already existing sub-consortium for the Large-Sized Telescopes, all telescope classes are now covered, and the provision of telescopes as in-kind contributions to CTAO is being organised. + +Excellent progress was also reported by the Science Working Groups. The development of Consortium papers is progressing well, with two papers currently under final review by the Consortium. The multi-wavelength and multi-messenger coordination is also taking shape, moving now from the identification of CTA’s needs to the securing of access to data. The Analysis and Simulations Working Group reported on the development of analysis pipelines and their application to first real data from prototype telescopes. To improve the performance of event reconstruction and classification, the use of deep learning methods is also being explored. The planning of the next large-scale Monte Carlo simulation dubbed “Prod5” is basically finished, and the production recently began. Finally, a new task group was set up to address the still open questions related to the Instrument Response Functions of CTA. + +The project also reported important progress during the meeting, with the cost book review completed and its approval now achieved during the June CTAO Council meeting. The CTAO Council has furthermore approved the deployment of five MSTs on the CTA-North site as pathfinder telescopes, paving the way for a gradual build-up of the array. Critical Design Reviews (CDRs) for the MST telescope and cameras are planned later this year, and an engineering review for the SST is scheduled for this summer. First steps towards the definition of a science plan for the construction phase were also presented. + +During its meeting, the Consortium Board discussed issues related to Consortium publications, the improvement of the IT support for the Consortium activities, a low-carbon charter for Consortium members, and future Consortium meetings. Due to the uncertain situation related to the COVID-19 pandemic, it was decided to also hold the next Consortium meeting in the second semester of 2020 as an online meeting. Hopefully, the situation resumes to normal in 2021 allowing again for in-person meetings.

He cared and took the time to organize enriching educational experience: on one occasion, he led a project to develop a cloud chamber at LLR, pushing the undergraduate students to think seriously about the project, treating it as if it were to be launched into space. He accomplished this by having them defend their design to a product assurance engineer and by engaging in extensive GEANT4 simulations.

These jets, which can be either intermittent or persistent structures depending on the specific state of the system, emanate from the vicinity of the compact object and can expand light years away from the binary system. + +The word “microquasar” was used for the first time in 1992 to describe the Galactic binary system 1E1740.7–2942, characterized by radio-emitting double-sided jets [1]. The jets resembled the relativistic collimated outflows launched by quasars (active galaxies with supermassive black holes at the centre that devour its surrounding material), although, in the latter case, the powerful jets reach distances of up to millions of light years. Thus, we can say that microquasars, as their name suggests, are the little siblings of the quasars, sharing multiple similarities. One of the advantages of studying microquasars is that, given their smaller size, processes inside the system and jets happen on a shorter timescale, allowing scientists to analyze rapid variabilities in their emission. + +Microquasars’ outflows are efficient sites of extreme particle acceleration and are responsible for transient and persistent non-thermal radiation, spanning from radio to gamma-ray energies. Nevertheless, the emission at GeV and TeV energies from microquasars has only been sporadically observed up to this point, making these systems a class of non-thermal emitters that is actually “elusive” in the gamma-ray energy range. With its improved sensitivity compared to the current gamma-ray instruments, CTA will be fundamental to the study of these systems and the physical processes inside the jets. In particular, two microquasars, SS 433 and Cygnus X-1, have been drawing attention over the past few years. + +Prolonged observations of SS 433 with the High Altitude Water Cherenkov (HAWC) observatory were able to resolve two lobes at energies of ~20 TeV related the terminal parts of its jets, where the relativistic outflows interact with the surrounding environment [2]. According to the authors, to produce such a TeV signal, the system needs to accelerate particles up to PeV energies along the jets and, therefore, SS 433 might be a so-called Galactic PeVatron. Furthermore, a recent study with the *Fermi*-LAT has reported sub-TeV persistent emission from a site lying in the proximity of the eastern lobe [3]. Still some mysteries remain: What is the maximum energy to which the particles are accelerated in the jets? Does gamma-ray emission occur near or inside the binary system? What are the exact acceleration sites and mechanisms? CTA’s excellent angular resolution will play a key role in answering these questions. + +In the Cygnus region, three microquasars have been observed above 50 MeV: Cygnus X-1, Cygnus X-3 and V404 Cygni (see e.g. [4,5]). The case of Cygnus X-1 is intriguing. At GeV energies, short-time transient emission [6] and persistent emission coming from the jets [7] have been detected, while at TeV energies, only a hint during a short hard X-ray flare has been reported by MAGIC [8]. Therefore, even though theoretically predicted, a clear TeV component has not yet been detected. According to recent simulations, the CTA-North array, located in La Palma (Spain), would detect a short transient event, similar to the hint reported by MAGIC, in just a few minutes, and would be able to characterize the TeV persistent emission from the jet with a set of prolonged observations (see Figure 1). + +![](/uploads/Fig1_v3_b-1600x1099.png) + +With CTA, we expect to unveil the timing of a possible TeV flare in a multi-wavelength context, the maximum limit of acceleration along the jets, the nature of the emission mechanisms (leptonic/hadronic) responsible for the very high-energy gamma-ray radiation and more.  Particularly, CTA’s unprecedented sensitivity between 20 GeV to 300 TeV will allow us to delve into these sources like never before: at the lowest energies, we will be able to comprehend the physics mechanisms between the GeV and TeV gamma-ray component (e.g., in Cygnus X-1) and, at the highest energies, we will be able to open a new window at the high end of the electromagnetic spectrum to study the jet-medium interaction (e.g., in SS 433). Thanks to CTA’s improved angular resolution, lower energy threshold and fast telescope repositioning to respond to external triggers for transient events, a better understanding of the physics of extreme particle acceleration in microquasars will finally be well within our grasp. +— +[1] Mirabel, I.

Throughout the past decade, several new astrophysical messengers have provided us with new insights into the most violent phenomena in the Universe: starting with high-energy gamma rays, the detection of an astrophysical flux of high-energy neutrinos and the first direct detection of gravitational waves. Building on these significant breakthroughs, many high-energy astrophysics observatories and groups started to work towards a dream that is now coming true: multi-messenger astrophysics, which, via the exchange and combination of data from very different observatories and messengers, opens new windows and provides unprecedented insights into the most violent phenomena ever observed. + +The most striking example illustrating the viability of this approach is the detection of electromagnetic signals complementing gravitational waves from the merger of a binary neutron star system. This event, named GW170817, is probably the best-covered astrophysical phenomenon in recent history. Thanks to the huge effort by observatories around the world, it provides for the first time an observational link between binary mergers, short gamma-ray bursts and optical emissions known as kilonovae, and resolves the origin of heavy elements in the Universe [1]. As a hint for the expected CTA performance, H.E.S.S. was the first ground-based instrument to observe the region covering the source region, including the kilonova named SSS17a/AT2017gfo. No high-energy gamma-ray emission could be detected during an extensive observation campaign covering timescales from a few hours to several days after the gravitational wave event [2]. + +The image below illustrates the simulated response of CTA follow-up observations of the gravitational wave event GW170817. Thanks to the large field-of-view of CTA, only two individual pointings would be necessary to cover most of the localization region provided by the LIGO and VIRGO gravitational wave interferometers (coloured region). Combined with its high sensitivity, CTA will therefore be able to efficiently search for associated high-energy gamma-ray emission. + +![](/uploads/Fabian2.png) + +*Credit: F. Schüssler, IRFU/CEA Paris-Saclay* + +This very recent example just scratches the surface of the enormous potential of these searches. It is all made possible through the rapid exchange of information across very different instruments and the subsequent joint data analyses. These collaborations build on a long history in astronomy of telescopes at far corners of the Earth jointly monitoring variable objects as the globe rotates. The real-time exchange of information in the study of gamma-ray bursts was introduced in the late 1990s. It is this culture of open data and fast information exchange that will ensure the success of multi-messenger astrophysics. + +CTA, with its large field-of-view, extremely fast reaction to alerts and very-high sensitivity, is well suited to lead this revolution. The follow-up observations of gravitational wave events have been assigned the highest priority in CTA’s key science project on transient phenomena.

The election of the new CB chair was carried out electronically, and on December 15 the result was announced: Vitor de Souza will serve as the new CB chair. + +We would like to use this opportunity to thank Jürgen Knödlseder for 9 years of service as CB chair. Elected in 2013, Jürgen chaired over 30 CB meetings, and guided discussions in the CB over a wide range of topics, including CTA science goals & performance requirements; site evaluation and selection; optimization of array layouts; staging scenarios; data rights and data policies; the evolution of the Consortium towards CTAO construction and operation; or the relation between CTAC and CTAO. Recurrent CB topics concerned the SWG and ASWG coordinator appointments, assembling list of candidates, asking and sometimes convincing the persons to stand for the election, and organizing the election as well as discussion of dates, locations and formats of Consortium meetings. During Jürgen’s term, the number of country members in the Consortium increased considerably, the SAPO mandate and organization were refined, along with the publication policy, as well as the SWG and ASWG and the rotation schemes for coordinators. + +In his role as CB Chair, Jürgen was extremely engaged, ensuring that the CB is properly informed and involved, that the votes and discussions are properly documented, and that well-defined procedures are established through governance documents. Jürgen has truly shaped the way how the CB works, and with that of course how the Consortium works. An important and lasting achievement is that Jürgen raised awareness regarding the environmental footprint of the Consortium, and the Carbon footprint in particular of in-person Consortium meetings; even beyond Covid, his arguments and concerns will have a strong impact on the way we organize meetings.

The LST-1 Critical Design Review and the ACADA Preliminary Design Review were declared as “PASSED”, the SST Engineering Review was organised and held, and the NectarCAM Critical Design Review is under preparation. In addition, the Hosting Agreement for the SDMC in Zeuthen was signed, and a cooperation agreement with CERN that will give access to CERN resources and services is under preparation. Preparation of the array sites in the North and the South is continuing, including the conceptual design of the Operations building and a site survey in the North, and the construction planning in the South. + +The telescope teams have also reported good progress. The LST-1 commissioning proceeds well despite the Covid-19 pandemic, with as recent highlights the detection of pulsations from the Crab pulsar and the detection of the blazars Mrk 421 and Mrk 501.

Vice-Chair Giampaolo Vettolani added, “We hope our supporters and scientists from Namibia and Mexico will continue to contribute scientifically and technically to CTA, driven by the common interest to build the best possible instrument for the entire community.” + +In order to optimize the coverage of the night sky, the CTA Observatory will consist of about 100 telescopes on the [southern site](https://www.ctao.org/emission-to-discovery/array-sites/ctao-south/) and about 20 telescopes on the [northern site](https://www.ctao.org/emission-to-discovery/array-sites/ctao-north/). + +“This is a significant step towards realizing CTA as the most advanced instrument on the planet for very high-energy gamma-ray astronomy and towards making CTA’s full power available to the science community early in the next decade,” said CTA Co-Spokesperson Rene Ong. + +The southern site is less than 10 km southeast of ESO’s existing Paranal Observatory in the Atacama Desert, which is considered one of the driest and most isolated regions on earth – an astronomical paradise.

They were discovered by Victor Hess in 1912, when he measured an increasing radiation level in the atmosphere with altitude, using his balloon to reach a height of 5.3 km. He rightly postulated the extraterrestrial origin of cosmic rays and was awarded the Nobel Prize in Physics in 1936 for his discovery. + +Decades of measurements helped to construct the energy spectrum of cosmic rays observed from Earth. It is one of the most famous plots of modern physics, exhibiting a remarkable power law in energy over several orders of magnitude (see inset in Figure 1). This power law has a break in energy at a few Peta-electronvolts (PeV, + +1015 eV), which is referred to as the *knee*. Below the *knee*, cosmic rays are believed to be of Galactic origin, but the sources where they are produced are still unknown. Sources capable of accelerating particles up to at least PeV energies are called PeVatrons, and astronomers are actively on the hunt for these extreme accelerators within our Galaxy. + +Several strong arguments suggest that the fast shock wave in the remnants of exploding stars (Supernova Remnants; SNRs), could be the acceleration site of cosmic rays and thus, the PeVatrons, too. Thus far, an emission detected by HAWC associated to SNR G106.3+2.7 suggests cosmic-ray proton acceleration up to PeV, but other scenarios related to electron acceleration cannot be ruled out [1]. Therefore, SNRs have not been established as a Galactic PeVatron yet, leaving this hypothesis still open. + +![](/uploads/ScienceArticle_WH_RO_AFB.docx-1024x852-1.png) + +*Figure 1: The origin of cosmic rays is explored with neutral messengers, such as gamma rays. The inset shows the cosmic-ray energy spectrum observed from Earth with the main spectral features. Credit: HAP/A. Chantelauze* + +Understanding the origin of cosmic rays using direct measurements is an impossible task due to the presence of interstellar magnetic fields that deviate the path of these charged particles before they reach Earth. Neutral messengers generated by cosmic-ray interactions, such as gamma rays and neutrinos, are used to determine the origin of cosmic rays (Figure 1). + +The gamma-ray energy is approximately a factor 10 lower than the parent cosmic-ray energy [2]. Thus, we can probe PeVatrons by searching for gamma-ray emission at energies up to 100 TeV and above. Current Imaging Atmospheric Cherenkov Telescopes (IACTs) have limited sensitivity above a few tens of TeV, which hampers measurements of the most interesting energy range for PeVatron investigation. Besides the putative SNR G106.3+2.7, so far, the discovery of only one PeVatron in our Galaxy has been reported by the H.E.S.S. Collaboration, located within the Galactic Center region, possibly connected to past active phases of the supermassive black hole Sgr A* [3]. This source is not powerful enough to explain the total amount of cosmic rays arriving on Earth; however, its detection has opened up new possibilities for the acceleration of PeV cosmic rays in our Galaxy, indicating that other types of astrophysical sources besides SNRs can be Galactic PeVatrons. + +CTA, the next generation ground-based gamma-ray observatory, will include up to 70 [Small-Sized Telescopes](https://www.ctao.org/emission-to-discovery/telescopes/sst/) (SST) in its [southern array](https://www.ctao.org/emission-to-discovery/array-sites/ctao-south/) (CTA-South), located in the Atacama Desert in Chile. The SSTs will be responsible for the high end of the observatory’s sensitivity between ~5 and 300 TeV. The large detection area of the SSTs improves by several orders of magnitude the gamma-ray sensitivity at TeV energies with respect to current IACTs and opens a new window to the unexplored Universe up to 300 TeV, boosting the probability of detecting PeVatrons. + +![](/uploads/SNR.png) + +*Figure 2: Simulated images of the bright SNR RX J1713.7-3946, one of the main targets of CTA to study cosmic-ray acceleration, which illustrate different gamma-ray emission scenarios [6]. Credit: CTA Consortium* + +As part of its core scientific objectives, CTA will perform PeVatron searches using two strategies. The first is to observe known potential PeVatron candidates, provided by current IACTs and water Cherenkov detectors like HAWC [4,5], showing emission above a few tens of TeV together with no significant suppression in their gamma-ray spectrum. An ideal target is the SNR RX J1713.7-3946, due to its high brightness and many existing multiwavelength studies, whose CTA simulated emission under different theoretical scenarios is shown in Figure 2. The second strategy is to perform deep follow-up observations of new PeVatron candidates discovered during CTA’s Galactic Plane survey, which will provide an unprecedented dataset of new sources owing to the improved CTA sensitivity and angular resolution. + +CTA will therefore be a unique instrument for PeVatron hunting, capable of detecting with unprecedented sensitivity and accuracy TeV gamma rays produced by PeV cosmic rays, which will significantly increase our chance to solve an almost 110-year-old mystery:  Where do Galactic cosmic rays originate? + +References: + +[1] Albert, A. et al.

Not to mention, “Citizen of the world” is an expression that suits him perfectly: he has lived and worked in Germany, Chile, the U.S.A. and Italy. His extensive experience in different fields and for world-class observatories, makes Bernhard an excellent addition to the CTAO team. In this interview, Bernhard shares more about himself and his work… + +#### **Tell us about yourself and how you came into your present role.** + +I like to start by saying that I am an engineer. I highlight it because I am passionate about building things, tangible things that can move. Hence my passion for participating in the construction of observatories. In fact, I began to participate in the construction of observatories more than 25 years ago, when I was a student. Although I was born in Germany, at the age of 17 I went to study at a university in Chile, where I was able to participate in the characterization of the Gemini South site and work in a cosmic-ray laboratory in Antarctica. And this is when I fell in love with astronomical observatories. + +After a few years of working for ESO in Chile with optical instruments, I moved with my wife to Italy to not only participate in a new project, Virgo, but also to see another part of the world. Then, my next challenge led me to work with another type of technology: radio antennas for the ALMA Observatory. I spent time in the U.S. before returning to Chile, where I stayed for 14 years. + +Thus, I worked in projects under construction and even under commissioning, but I was missing being able to work on projects in the design and early planning phase in preparation for construction and operation. And that’s where the CTAO came in. The CTAO was clearly among the world-class projects that could give me a new challenge, and in which I felt I could help in the early definitions. In addition to this professional inquisitiveness, I also wanted to show my family another country, teach my children that we live in a diverse, international world. And so, I arrived at the CTAO’s Science Data Management Centre (SDMC) in Germany to work as ACADA Deputy Coordinator, as well as Quality Manager. + +#### **What does an ACADA Deputy Coordinator and Quality Manager do and why is it important to the future of CTAO?** + +As ACADA (Array Control And Data Acquisition system) Deputy Coordinator, my goal is to support and help the development of this key system. For me, CTAO is more of a software observatory than a hardware observatory, so there is a strong focus on developing all the fundamental software tools for the operation of the Observatory in a timely manner. And the truth is that I have been very lucky to join a really good team, very structured and where everything was clear, so it was quite simple to integrate. + +On the other hand, as a Quality Manager, my focus is the establishment of processes, initially focused on construction, so that we all work approximately in the same way or reconcile appropriately the different forms of development in a fair and transparent manner for all parties. The definition of such processes needs to also consider the operation phase: unlike isolated telescopes, observatories have periods of years of coexistence between construction and operation. Thus, telescopes are being added at the same time as early science is being done. For this reason, we already must think about how to make this coexistence possible. In short, make use of a work methodology that allows us to converge and optimize the development of the Observatory. + +#### **What are you working on now?** + +Regarding ACADA, our main goal now is launching “release 1,” a very important milestone. This first release of ACADA is limited to the Large-Sized Telescope prototype, the LST-1, so we can test the software and build solid foundations for future releases with which the array of telescopes will be operated. Part of my job is the coordination between the Computing groups of CTAO and LST-1 and efficiently planning the integration of this software in the common interfaces. + +As Quality Manager, I am working on updating the Observatory’s Operation Plan. An Operation Plan must include concepts of scientific observation (e.g., how observation proposals are managed) and technical operations (e.g., how we actually acquire the data). It also has to consider the specific characteristics of each array site (e.g., the differing geophysical and administrative conditions at the telescope sites as well as the responsibilities of the headquarters or the SDMC). All the processes and who participates in what way, on-site and off-site, must be described to be able to evaluate the necessary resources and technical requirements. And it really goes beyond just software or hardware. For example, operating a telescope is not running it, it’s maintaining it, it’s having a vehicle that allows you to access it, it’s having a place where the operators can have lunch! And of course, we must also consider what happens after the data is taken. That is, the experience of the scientific users who will analyze our data, as in the tools and support they will need. Each and every one of the little checkboxes of this process has its relevance for CTAO to work well, and I am happy to be able to contribute to this. diff --git a/src/content/news/qanda-with-director-administration-stephan-haid.md b/src/content/news/qanda-with-director-administration-stephan-haid.md new file mode 100644 index 0000000..afa5933 --- /dev/null +++ b/src/content/news/qanda-with-director-administration-stephan-haid.md @@ -0,0 +1,31 @@ +--- +title: "Q&A with Director of Administration, Stephan Haid" +description: "From Germany to Ghana, from DESY to the CTAO, Stephan Haid has worked with scientists, technologists, and administrators worldwide in various fields to reach his current position as CTAO Director of Administration.

We sat down with Roberta to learn more about her and her work toward making the CTAO a world-class observatory… + +#### **Tell us about yourself and how you came into your present role.** + +I decided to study Physics when I was 13 years old. At that age, I discovered what an internal combustion engine was at school and found it fascinating — I think I always had a very experimental approach to all aspects of my life! However, it was clear to me that I did not want to be an engineer, but a physicist. What I was looking for was to study and understand the basic principles of science. + +This is how I started my Physics degree at the Università di Padova (Italy), where I entered the field of astroparticle physics. Within this, I opted for gamma-ray astronomy and ended up doing my master’s thesis on the MAGIC telescopes, the preceding generation of the CTAO. + +Over the years, I participated and worked in the different instruments that compose the current generation of Imaging Atmospheric Cherenkov Telescopes or IACTs (H.E.S.S., MAGIC and VERITAS), where I had different coordination positions, especially focused on galactic physics. In fact, my field of study focused on the understanding of the very high-energy emission emitted by Galactic sources, such as rapid rotating and magnetized neutron stars (pulsars), their environment (Pulsar Wind Nebulae), or binary systems ejecting powerful jets (microquasars). + +My involvement with the CTAO started as a member of the Cherenkov Telescope Array Consortium (CTAC), where I served as Coordinator of the Galactic Working Group and worked in the development of software for data analysis and operation. When the position of Project Scientist was opened in 2019 at the CTAO gGmbH, I knew I wanted to apply: after almost 15 years dedicated to ground-based gamma-ray astronomy, being able to work directly in the definition of the first ground-based IACT observatory’s science was really exciting. + +#### **What does a Project Scientist do do and why is it important to the future of CTAO?** + +The Project Scientist is responsible for all science-related aspects of the Observatory, which involves working on different fronts. From one side, I have to ensure that all science requirements are met during the construction phase: if, for example, the engineers need to revise the design of an instrument, I work with them to guarantee that the change’s impact on the science performance of the Observatory is acceptable. From another side, I am the Observatory’s interface with the scientific community. Thus, I collect science users’ feedback and proposals, and work together with them to define the science cases and priorities for the CTAO. + +Moreover, as Project Scientist, I had to recently evaluate the scientific implications of the Observatory’s reduced configuration. The CTAO benefits from a modular configuration and, while the ultimate goal is to have more than 100 telescopes between two sites, the approved configuration to be built based on current available funds, includes 64 telescopes. The definition of such configuration, named Alpha Configuration, and the geographical position of all elements (telescopes, calibration systems and atmospheric characterization devices) was the result of a meticulous optimization process for each array’s scientific capabilities, carried out in collaboration with the CTAC members. + +#### **What are you working on now?** + +Now that the scope of the CTAO construction project (its Alpha Configuration) has been defined, I am advancing in the definition of the Scientific Operations Concept, and this is really important: at the end, we are building this Observatory to optimize the scientific outcomes and discoveries and for that, we need to have clear processes and workflows behind observation planning, data collection, reduction and dissemination, so that observations are carried out as expected and data is properly made available to the worldwide scientific community. + +In preparation also for future data, I am working on the CTAO Science Data Challenge (SDC), our first publicly available data challenge to broaden the scientific community and allow astronomers from any field to become familiar with CTAO’s scientific capabilities and data analysis.

Having control over these three characteristics, which are in a tight mathematical relationship and influencing each other, will give us a high confidence in the performance of our product over its lifecycle.

Sometimes, the prioritization of these activities tends to be bypassed or postponed due to the demands of the project in other areas. My job is to keep these activities top of mind through the development stages, construction and service of this project. That’s why my work, now, focuses on education, support and guiding the contributors of CTA technology through the analyses required by the Project Office. In the long term, the results of these activities will be rolled up and applied to the system level, which will continue to improve the confidence of the Observatory’s performance throughout its operational lifetime. With our progress and the support from senior management received for the RAM Process, thus far, I am very confident that we are on the right track. diff --git a/src/content/news/redshift-why-does-distance-matter-to-cta.md b/src/content/news/redshift-why-does-distance-matter-to-cta.md new file mode 100644 index 0000000..3c18c50 --- /dev/null +++ b/src/content/news/redshift-why-does-distance-matter-to-cta.md @@ -0,0 +1,40 @@ +--- +title: "Redshift: Why Does Distance Matter to CTA?" +description: "Only by knowing the distance of the objects we observe can we begin to understand their physical nature.This is particularly true with one of CTA’s main targets, Blazars, which are the most numerous class of extragalactic sources in the…" +date: 2021-06-02 +category: news +author: CTAO +cover: /uploads/800px-Redshift.svg-1-768x433.png +draft: false +--- + +Originally published in the [May 2021 issue of the CTA Newsletter](https://mailchi.mp/892f3f0c743d/cta-newsletter-december2020-english). *Written by: Paolo Goldoni* + +* +*Only by knowing the distance of the objects we observe can we begin to understand their physical nature. In 1923, Edwin Hubble demonstrated that some of the so-called “nebulae” he saw were, actually, galaxies located millions of light years away. He did so by observing a particular type of variable star in the “nebulae,” the Cepheids, discovered by Henrietta Leavitt a few years before, whose period of variation is linked to their luminosity. The period of the Cepheids in the nebulae that Hubble observed implied such a luminosity that they were undoubtedly extragalactic. In doing so, he also established a correlation between the distance and the redshift of the optical spectra of the galaxies he observed. Since then, the redshift is the quantity most used to measure the distance of extragalactic objects. + +The redshift is an increase of the light’s wavelength (decrease of energy) that occurs when a light source moves away from the observer. It is typically measured in optical and near-infrared by the spectral lines of the source (Figure 1). In extragalactic astronomy, the redshift (also called cosmological redshift) is due to the expansion of the Universe that increases the distance between the galaxies and the Earth. + +![](/uploads/800px-Redshift.svg-1-1.png) + +*Figure 1.

Arrows indicate the redshift, i.e. the increase of the wavelengths (lower energy). Credit: Georg Wiora* + +### Blazars and their Distance in Very High-Energy Astronomy + +As for all astronomical instruments, the distance of the observed object is very important to CTA, too. This is particularly true for blazars, the most numerous class of extragalactic sources in the very high-energy (VHE) domain (above tens of GeV). Blazars are a class of Active Galactic Nuclei (AGNs) – compact regions at the centre of galaxies with strong and variable emission across the electromagnetic spectrum. Their emission is caused by accretion on the central supermassive black hole. During the accretion process, a jet of relativistic particles is emitted from the vicinity of the black hole, whose radiation spans from radio to gamma rays. In blazars, the jet is pointed towards the observer. + +In the most numerous class of VHE blazars, BL Lacs, the jet emission dominates over the galaxy emission in the optical range. The latter is crucial for redshift measurement, but because of the stronger jet emission, their redshift is very difficult to estimate. Less than half of the known BL Lacs have a known redshift and, with such a low percentage, it is not possible to estimate their properties as a whole: we do not know with precision their density in the Universe and their evolution with time, and their emission cannot be modelled with great precision. + +The lack of knowledge of blazars’ redshift (or distance) is particularly problematic in the VHE domain: the blazars’ VHE spectra we observe with our telescopes are distorted by the interaction of the VHE gamma rays with photons and particles encountered along their travel to Earth. This distortion is dependent on the distance and so, its value is needed to correct the spectra and obtain the real emission of the source. Conversely, if a model of the source emission is assumed, the properties of the intergalactic medium can be extracted. + +Several physical processes are responsible for the distortion of the VHE spectra, but in this article, we will concentrate on the Extragalactic Background Light (EBL), which is the integration of all the optical and near-infrared light emitted by the stars and galaxies during the history of the Universe, and whose value, usually measured in the optical range, is not very well known yet. + +The optical photons from the EBL interact with the VHE gamma rays from blazars, annihilating and giving rise to an electron and a positron (see Figure 2). This effect is strongly dependent on the redshift of the blazar and so, by knowing the redshift and observing VHE gamma rays, we can measure the EBL. + +![](/uploads/gpropa_300ppi.png) + +*Figure 2: Cosmic journey of gamma rays from a distant galaxy down to the CTA Observatory. Among other physical processes, some gamma rays produce electron-positron pairs when interacting with EBL photons (top left process)* + +This measurement is one of the main science cases of CTA. Thanks to its unprecedented sensitivity, wide field of view and extended spectral range, in fact, CTA will obtain many more blazar spectra and with a much higher signal-to-noise than previous instruments. These spectra, in principle, will allow to measure the EBL with precision comparable to the optical one, allowing a fundamental cross-check between the two methods. Unfortunately, if the distance of the blazars is not known, the quality of the measurements in general can be affected. For this reason, a group of CTA Consortium members has performed observations from some of the world’s greatest optical observatories (ESO, Keck, SALT) in order to measure the redshift of bright gamma-ray blazars that likely will be detected with CTA. A paper presenting the measurement of 11 blazar redshifts, which will be crucial for future CTA scientific studies, has recently accepted for publication by Astronomy and Astrophysics Journal [1]. This effort is just beginning, and it will increase the number of gamma-ray blazars with known redshift, thus, helping to maximise the scientific return of CTA. + +[1] Goldoni, P.

It lays the groundwork for the future of gamma-ray astrophysics. “We’ve established this new technology, which will measure gamma rays with extraordinary precision, enabling future discoveries,” said Vandenbroucke. “Gamma-ray astronomy is already at the heart of the new multi-messenger astrophysics, and the SCT technology will make it an even more important player.” + +The use of secondary mirrors in gamma-ray telescopes is a leap forward in innovation for the relatively young field of very-high-energy gamma-ray astronomy, which has moved rapidly to the forefront of astrophysics. “Just over three decades ago, TeV gamma rays were first detected in the universe, from the Crab Nebula, on the same mountain where the pSCT sits today,” said Vandenbroucke. “That was a real breakthrough, opening a cosmic window with light that is a trillion times more energetic than we can see with our eyes. Today, we’re using two mirror surfaces instead of one, and state-of-the-art sensors and electronics to study these gamma rays with exquisite resolution.” + +“The initial pSCT Crab Nebula detection was made possible by leveraging key simultaneous observations with the co-located [VERITAS](https://veritas.sao.arizona.edu/) (Very Energetic Radiation Imaging Telescope Array System) observatory.  We have successfully evolved the way gamma-ray astronomy has been done during the past 50 years, enabling studies to be performed in much less time,” said Wystan Benbow, Director, VERITAS. “Several future programs will particularly benefit, including surveys of the gamma-ray sky, studies of large objects like supernova remnants, and searches for multi-messenger counterparts to astrophysical neutrinos and gravitational wave events.” + +Located at the Fred Lawrence Whipple Observatory in Amado, Arizona—the largest field site of the [Center for Astrophysics | Harvard & Smithsonian](http://cfa.harvard.edu)—the pSCT was inaugurated in January 2019 and saw first light the same week. After a year of commissioning work, scientists began observing the Crab Nebula in January 2020, but the project has been underway for more than a decade. + +“We first proposed the idea of applying this optical system to TeV gamma-ray astronomy nearly 15 years ago, and my colleagues and I built a team in the US and internationally to prove that this technology could work,” said Prof. Vladimir Vassiliev, Principal Investigator, pSCT. “What was once a theoretical limit to this technology is now well within our grasp, and continued improvements to the technology and the electronics will further increase our capability to detect gamma rays at resolutions and rates we once only ever dreamed of.” + +The pSCT was made possible by the contributions of thirty institutions and five critical industry partners across the United States, Italy, Germany, Japan, and Mexico, and by funding through the U.S National Science Foundation Major Research Instrumentation Program. + +“That a prototype of a future facility can yield such a tantalizing result promises great things from the full capability, and exemplifies NSF’s interest in creating new possibilities that can enable a project to attract wide-spread support,” said Nigel Sharp, Program Manager, National Science Foundation. + +The SCT is being proposed to cover the core of CTA’s energy range (around 80 GeV – 50 TeV). The SCT’s two-mirror optical system is designed to better focus the light for greater imaging detail and improved detection of faint sources. A total of 40 telescopes (25 in the southern hemisphere and 15 in the northern hemisphere) are planned to cover this energy range. “CTA has been exploring the dual-mirror technology since the very beginning of the project with the Small-Sized Telescope prototypes and the SCT for the Medium-Sized Telescope,” says Federico Ferrini, Managing Director of the CTA Observatory. “The results obtained by the pSCT team re-confirm the advantages of advancing the technology for Cherenkov astronomy and the great potential it will bring to CTA.” + +“The pSCT, and its innovations, are pathfinding for the future CTA, which will detect gamma-ray sources at around 100 times faster than VERITAS, which is the current state of the art,” said Benbow. “We have demonstrated that this new technology for gamma-ray astronomy unequivocally works. The promise is there for this groundbreaking new observatory, and it opens a tremendous amount of discovery potential.” + +### About the pSCT + +The SCT optical design was first conceptualized by U.S. members of CTA in 2006, and the construction of the pSCT was funded in 2012. Preparation of the pSCT site at the base of Mt. Hopkins in Amado, AZ, began in late 2014, and the steel structure was assembled on site in 2016. The installation of the pSCT’s 9.7-m primary mirror surface — consisting of 48 aspheric mirror panels — occurred in early 2018, and was followed by the camera installation in May 2018 and the 5.4-m secondary mirror surface installation — consisting of 24 aspheric mirror panels — in August 2018.

The flash of bluish light only lasts a few billionths of a second and is extremely faint. Gamma-ray telescope cameras are sensitive to these faint flashes. The pSCT camera triggers when several neighboring pixels detect light within a few nanoseconds of one another. The camera has a modular design, with 25 modules each containing 64 pixels. The central module is not yet installed in order to shine a laser beam along the central axis for telescope alignment, and a neighboring module was disabled during the test run. The pixel amplitudes are raw and uncalibrated, but the early results are a major milestone for the SCT team. + +The SCT’s dual-mirror optical system improves on the single-mirror designs traditionally used in gamma-ray telescopes by dramatically enhancing the optical quality of their focused light over a large region of the sky and by enabling the use of compact, highly-efficient photo-sensors in the telescope camera. The pSCT commissioning will continue in 2019, including alignment of the mirror panels of both the primary and secondary mirror, positioning of the camera with respect to the focal plane and calibration of the camera data.  A project is underway to increase the number of pixels in the pSCT camera by a factor of seven in order to match the wide field of view of the mirrors. + +CTA will consist of 118 telescopes split between a southern array in Paranal, Chile and a northern array on the island of La Palma, Spain.

We hope CTA will supersede VERITAS around 2023, and it will be used to continue to build upon the 50 years of gamma-ray research at the Whipple Observatory and elsewhere.” + +“I am very pleased to congratulate our colleagues that have conceived and realised such a promising prototype for the Medium-Sized Telescopes, a major component of the family of instruments that will characterise the CTA Observatory,” said Federico Ferrini, Managing Director of the CTAO. + +#### **About pSCT** + +The SCT optical design was first conceptualized by U.S. members of CTA in 2006, and the construction of the pSCT was funded in 2012. Preparation of the pSCT site at the base of Mt. Hopkins in Amado, AZ, began in late 2014, and the steel structure was assembled on site in 2016.  The installation of pSCT’s 9.7-m primary mirror surface —consisting of 48 aspheric mirror panels—occurred in early 2018 and was followed by the camera installation in June 2018 and the 5.4-m secondary mirror surface installation—consisting of 24 aspheric mirror panels—in August 2018. Leading up to the inauguration and in preparation for first light, scientists opened the telescope’s optical surfaces in January 2019.  The SCT is based on a 114 year-old dual-mirror optical system first proposed by Karl Schwarzschild in 1905, but only recently became possible to construct due to the critical research and development progress made at both the Brera Astronomical Observatory and Media Lario Technologies Incorporated in Italy.

To celebrate this milestone, Brandenburg’s Science Minister, Manja Schüle, and Head of the Sub-Department Large-Scale Facilities and Basic Research at the Federal Ministry of Education and Research, Volkmar Dietz, participated in the ceremony on campus, together with the Managing Director of the CTAO gGmbH, Federico Ferrini and the Chairman of the DESY Board of Directors, Helmut Dosch. + +“DESY scientists have been involved in major international research projects in astroparticle physics for decades. The decision to locate the Scientific Data Management Centre of the international gamma-ray observatory CTAO in Zeuthen greatly enhances this research location in the state of Brandenburg, which is internationally established with researchers from more than 30 nations and has regional roots at the same time. Soon, not only will enormous amounts of data be processed and coordinated there. There will also be rooms for lectures, training and – more important than ever – for meetings,” says Manja Schüle, Minister of Research of the State of Brandenburg. “I am convinced that science and research will continue to bring people together in the future. But since Russia’s war of aggression on Ukraine, trusting institutional cooperation with Russian and Belarusian institutions is no longer possible. That is why we support DESY’s decision to suspend all scientific cooperation with Russia and Belarus. Science and research build bridges – but these must be built by both sides. In the face of this war in Europe, there must not and cannot be a simple ‘business as usual’.

The CTAO’s unparalleled accuracy and unprecedented energy range (20 GeV- 300 TeV) will provide novel insights into the most extreme and powerful events in the Universe, addressing questions in and beyond astrophysics falling under [three major themes:](https://www.cta-observatory.org/science/study-topics/) Understanding the origin and role of relativistic cosmic particles, probing extreme environments (such as the vicinity of black holes) and exploring frontiers in physics (including the study of dark matter). To do so, CTAO has two telescope array sites: One in the northern hemisphere in La Palma, Spain, and one in the southern hemisphere in the Atacama Desert, Chile. The headquarters of the CTAO is hosted by Italy and the National Institute for Astrophysics (INAF) in Bologna, and the Science Data Management Centre is hosted by Germany and the Deutsches Elektronen-Synchrotron (DESY) in Zeuthen. CTAO will also be the first of its kind to be open to the world-wide astronomical and particle physics communities as a resource for data from unique, high-energy astronomical observations. + +The preparation of the design and implementation of the CTAO is managed by the interim legal entity CTAO gGmbH (CTAO gGmbH) until the final legal entity is achieved, the CTAO ERIC (European Research Infrastructure Consortium) in charge of the construction and operation of the Observatory.

CTA será el principal observatorio mundial para la astronomía de muy altas energías durante más allá de la próxima década, y será el primer observatorio de rayos gamma terrestre abierto a las comunidades globales de astronomía y física de partículas. CTA abordará algunos de los más grandes misterios en astrofísica, detectando rayos gamma con una sensibilidad sin precedentes y expandiendo increíblemente el catálogo de fuentes cósmicas, con más de 1000 fuentes nuevas. CTA es una infraestructura única y ambiciosa a gran escala que ampliará las observaciones a una región del espectro nunca antes investigada, abriendo una puerta totalmente nueva de nuestro Universo. CTAO gGmbH (gobernado por un [consejo de accionistas](https://www.cta-observatory.org/about/governance/) de 11 países y una organización intergubernamental, así como miembros asociados de dos países) es responsable de preparar el diseño e implementación del CTA Observatory. CTAO trabaja en estrecha cooperación con el Consorcio CTA formado por más de 1500 miembros de 31 países, que está a cargo de dirigir los objetivos científicos del Observatorio y está involucrado en el suministro de instrumentación. + +### Información Fundación Starlight + +La [Fundación Starlight](https://www.fundacionstarlight.org/), ubicada en Tenerife, es una entidad con personalidad jurídica propia – creada por el Instituto de Astrofísica de Canarias (IAC) y la Consultora Corporación 5 -, cuya finalidad principal es la protección del cielo nocturno, la divulgación astronómica, así como la coordinación y gestión del movimiento Starlight a nivel mundial.

There are many good reasons to design and implement the simplest and most harmonized system possible. In fact, a high degree of simplification will be a crucial success factor both during construction and operation. This need for harmonization applies to many subsystems and components of the array. One prominent area concerns the Small-Sized Telescope (SST) where harmonization is of very high importance due to the large number of units to be built, operated and maintained. + +Recognizing this, the CTA Observatory (CTAO) Project Office initiated discussions among the SST technical teams and shareholders in February 2018. As a result, the shareholders and those observers interested in providing SSTs as an in-kind contribution unanimously agreed on 9 May 2018 to implement only one SST design at the observatory. + +Concerning the process to arrive at a single SST design from three proposed designs, the CTAO Council mandated the CTA Project Manager to carry out an SST harmonization review involving external experts. Following this mandate, a Request for Information was issued on 1 August 2018, resulting in three submissions by the deadline of 31 October 2018. + +In November 2018, the Council unanimously approved the appointment of the members and charges of the external SST Harmonization Review Panel. The panel formed and conducted four remote conferences between 7 January and 4 March 2019 and held a final in-person meeting with the three SST teams on 27-29 March 2019. The report of the panel was delivered on 3 April 2019 and was immediately made available to the Council and the submitting teams. + +Based on the review findings and recommendations, and taking into account funding considerations, the CTAO Management formulated its proposal for a unified SST design (the “CTA-SST”). In its June 2019 meeting and following the CTAO Management proposal, the Council decided that “the CTA-SST design should be based on the ASTRI/CHEC design (pictured above), taking into account the experience gained from all designs.” Since June 2019, various discussions have taken place among the teams and shareholders interested in joining the common SST effort. It is expected that a CTA-SST Consortium will form by the Council meeting this November. The teams that have decided not to join the CTA-SST Consortium are looking into other areas of contribution to CTA. + +As expected, reaching this point has not been an easy process.

The CTAO’s unparalleled accuracy and broad energy range (20 GeV- 300 TeV) will help to address some of the most perplexing questions in astrophysics, falling under [three major themes](https://www.ctao.org/emission-to-discovery/science/study-themes/): understanding the origin and role of relativistic cosmic particles; probing extreme environments, such as black holes or neutron stars; and exploring frontiers in physics, searching for dark matter or deviations from Einstein’s theory of relativity. Additionally, the CTAO will play a key role in both multi-wavelength and multi-messenger fields in the coming decades thanks to its enhanced performance, which will allow it to provide fundamental gamma-ray information in the quest to probe the most extreme scenarios. + +To cover its broad energy range, the CTAO will use [three types of telescopes](https://www.ctao.org/emission-to-discovery/telescopes/): the [Large-Sized Telescopes (LST)](https://www.ctao.org/emission-to-discovery/telescopes/lst/), the [Medium-Sized Telescopes (MST)](https://www.ctao.org/emission-to-discovery/telescopes/mst/) and the [Small-Sized Telescopes (SST)](https://www.ctao.org/emission-to-discovery/telescopes/sst/). More than 60 telescopes will be distributed between two telescope array sites: [CTAO-North](https://www.ctao.org/emission-to-discovery/array-sites/ctao-north/) in the northern hemisphere at the Instituto de Astrofísica de Canarias’ (IAC’s) Roque de los Muchachos Observatory on La Palma (Spain), and [CTAO-South](https://www.ctao.org/emission-to-discovery/array-sites/ctao-south/) in the southern hemisphere at the European Southern Observatory’s (ESO’s) Paranal Observatory in the Atacama Desert (Chile). The [Headquarters](https://www.ctao.org/organisation/facilities/) of the CTAO is hosted by the Istituto Nazionale di Astrofisica (INAF) in Bologna (Italy), and the [Science Data Management Centre (SDMC)](https://www.ctao.org/organisation/facilities/) is hosted by the Deutsches Elektronen-Synchrotron DESY in Zeuthen (Germany). + +The CTAO is a [Big Data project](https://www.ctao.org/emission-to-discovery/data-and-computing/).

This makes dark matter an integral part of the so-called Lambda CDM Cosmological Model*, *which is what scientists use to describe the nature of the Universe according to its age, rate of expansion, history and contents. + +The existence of dark matter was first indicated in the 1930s when Swiss astrophysicist Fritz Zwicky found an anomaly as he was attempting to estimate the mass of large galaxy clusters using velocity measurements of individual galaxies within those clusters. He found the observed velocities were surprisingly high and postulated that the galaxies must be subject to a gravitational field much stronger than the one simply created by the mass of the observed systems and, thus, that the extra mass was the result of some form of unobserved “dark” type of matter. It took many scientists and 40 years to confirm these predictions, when American astrophysicist Vera Rubin provided robust observational evidences of the discrepancy between the predicted and observed rotational motion of stars in galaxies. Consequently, we now know that all galaxies sit at the centres of dark matter “halos,” characterized by a large central density but extending far beyond the visible galaxy’s size. + +While this and many more recent observations tell us that dark matter exists, its nature remains one of the greatest mysteries in science. + +### The dark matter mystery + +While the Standard Model of particle physics can explain the known particles and forces in the Universe, it cannot explain the existence of the ever-mysterious dark matter. It turns out that none of the particles that make up the Standard Model can completely satisfy the properties of dark matter as is required by cosmological observations. This gap implies that the Standard Model is incomplete and that the solution to the dark matter puzzle may be the link to other unsolved problems in particle physics, so its study could result in a significant breakthrough in our fundamental understanding of nature. + +Long-standing candidates for dark matter particles are the so-called Weakly Interacting Massive Particles or WIMPs. WIMPs appeared as a perfect dark matter candidate: theoretical particles with a mass of 100 -1000 times the mass of a proton (100 GeV – 1 TeV, approximately), which would naturally be produced with the right abundance in the early Universe. WIMPs, however, are far from being the only candidate. The wide range of proposed candidates spans about 40 orders of magnitude in mass: from extremely light but theoretically well-motivated particles like “axions“ over the much heavier “WIMPZillas” to macroscopic objects such as primordial black holes. + +### Hunting dark matter with CTA and gamma rays + +Gravity led to the discovery of dark matter’s existence, and it is still the only force known by which dark matter particles interact. However, if the dark matter particle is to complete the Standard Model of fundamental particles, the hope is that it will also be able to interact with other known particles, which could provide another opportunity for detection. + +Over the past few decades, the scientific community joined forces and devised a clear three-pronged strategy to (initially) search for WIMPs: via their production in particle collisions (like in the Large Hadron Collider in Geneva), via their scattering with Standard Model particles in dedicated detectors (called “direct detection” experiments) and through astrophysical observations. The main idea of the latter is that, in regions of the Universe where the dark matter density is high, dark matter particles could self-annihilate or decay, producing Standard Model particles that would reach us in the form of cosmic rays, as well as gamma rays. + +Thus, there is no doubt that CTA will act as a powerful dark matter discovery instrument: CTA will detect very high-energy gamma rays, a promising means to search for dark matter as gamma rays travel in straight lines (as opposed to charged cosmic rays) and are easier to capture than neutrinos. In particular, CTA will use its unprecedented sensitivity and energy resolution to capture gamma rays exactly over the energy range that corresponds to the heavier end of the WIMP masses. + +A variety of experiments over the past few decades have explored and excluded a significant fraction of the lighter WIMP candidates. However, while current instruments are not sensitive enough to detect some of the best-motivated WIMP models, their signals may be lurking exactly in CTA’s optimal energy range. In particular, in an upcoming CTA Consortium publication, CTA scientists demonstrate that the data from the planned survey of the Galactic Centre, where the density of dark matter is expected to be the highest, together with modern analysis techniques, will enable CTA to explore the “Holy Grail” region of the WIMP scenario in detail for the first time in an unrivaled way (see Figure 1). + +![](/uploads/CTA_GC_full_small.png) + +*Figure 1: Main frame: Artist’s view of the CTA-South array with the view of the Milky Way plane and the Galactic center.

Eckner; Rendering: Gabriel Pérez Díaz (IAC), Marc-André Besel  (CTAO); Simulations and inset: CTA Consortium.* + +Beyond WIMPs, another pending publication will look at the major role CTA will also play in exploring currently inaccessible aspects of axion-like particle dark matter models. Moreover, unlike current ground-based gamma-ray instruments, CTA will use three different types of telescopes (the Large-, Medium- and Small-Sized Telescopes) that will expand the energy range from 20 GeV up to 300 TeV. This, along with its better 10 percent energy resolution, will maximize CTA’s opportunities to detect spectral features associated with the interaction of dark matter particles of unexpected sources. + +The potential CTA brings to the hunt for dark matter is clear: it will exponentially increase our chances of solving the mystery behind dark matter in the next decade, and it could very well hold the key to unveiling completely unimagined discoveries in the field of fundamental physics. diff --git a/src/content/news/the-first-ctao-school-is-a-wrap.md b/src/content/news/the-first-ctao-school-is-a-wrap.md new file mode 100644 index 0000000..42ba97f --- /dev/null +++ b/src/content/news/the-first-ctao-school-is-a-wrap.md @@ -0,0 +1,47 @@ +--- +title: "The First CTAO School is a Wrap" +description: "The first CTAO School came to a close last week, and the organisers, instructors and students agree that it was a resounding success!

Bringing students from around the world to learn about a field and project we are so passionate about has been both fulfilling and fun. It was inspiring to watch the next generation of astroparticle physicists explore the fundamentals and frontier of the field, present their innovative ideas and work together to enhance each other’s knowledge, all against the backdrop of two phenomenal locations: Bertinoro and La Palma. And nothing was better than watching their joy and awe as they experienced working at the ORM, where three more LSTs are under construction and they had the opportunity to operate the ‘crown jewel’ of the CTAO-North site, the LST-1.

Scientists, however, also talk about low energies with CTA, which seems strange because those “low” energies are still a million times higher than the energy of X-rays. Therefore, it’s all a matter of perspective. The low energies from CTA’s perspective are those on the low edge (20 GeV to around 200 GeV) of its full energy range between 20 GeV and 300 TeV. Why are these low energies important and what do scientists hope to discover through their study? This is an overview of why scientists are scrambling to push for excellent sensitivity of CTA in this lower-energy band. + +![](/uploads/AGN_Redshift_compare-1.png) + +*Figure 1: Comparison of the potential observation of the very-high energy (VHE) Universe without CTA vs. with CTA. (Credit: adapted from D. Nakajima, ICRR)* + +The main physics case comes from the fact that the Universe is not entirely transparent to gamma rays because of the pair production between the gamma rays and the low-energy (this time really low, in the range of infrared and optical) photons of the background light, which has been filling the Universe since the first stars were created. This absorption is, however, energy dependent. So, if we can measure sources up to a few hundreds of million parsecs (which we call the nearby Universe!) with 1 TeV gamma rays, we can reach distances 10 times further with 100 GeV gamma rays, and at 20 GeV the Universe is transparent down to its origins (i.e. close to the Big Bang). This is why when CTA extends the sensitivity to lower gamma-ray energies, it increases the observable volume significantly, which is illustrated schematically in Figure 1. Through a larger accessible volume, we do not only increase fundamentally the number of sources and phenomena we can study, but, as is the case in all other wavelengths, we are also able to look into the past by measuring gamma rays that were produced billions of years before reaching the Earth. How were gamma rays produced in the past? Are gamma-ray sources in the distant Universe the same as close by? Are there new unseen phenomena? These are just a few of the questions that have convinced scientists to construct CTA’s Large-Sized Telescopes (LSTs), which will be devoted to the study of low-energy gamma rays. The LST prototype, LST-1, was recently inaugurated on CTA’s north site on the island of La Palma, Spain. + +![](/uploads/Fermi_CTA.png) + +*Figure 2: Comparison of CTA’s projected sensitivity and Fermi-LAT’s sensitivity at the same energies in the low-energy gamma-ray regime.* + +CTA will not be the only instrument sensitive to low-energy gamma rays. Gamma-ray satellites like *Fermi*-LAT, for example, also can measure in this energy regime. However, because satellites have a small collection area (<1m2), they struggle to measure transient phenomena. CTA’s collection area will be about a million times larger, which results in a much-improved sensitivity on short timescales where the hadronic background is unimportant. Fig. 2 demonstrates that for every short-time phenomena (like a flare) with a duration of less than a day, CTA’s sensitivity is many orders of magnitude better than the satellite-based *Fermi*-LAT. This is extremely important as we expect many time-variable phenomena like flares of extragalactic sources (e.g. blazars and radio galaxies), as well as galactic transients (e.g. gamma-ray binaries and soft gamma-ray repeaters) to happen on time scales of hours and below. CTA will be opening a new window in the time domain for these gamma-ray energies. + +Gamma-ray bursts (GRBs) are one of the clear targets for CTA in the low-energy gamma-ray regime. These bursts release most of their energy in the MeV domain and typically last only for 0.1-1000s, and their origin has been a matter of debate for several decades. The most prominent explanation is that the short GRBs (with a typical prompt emission of less than a few seconds) are mergers of black holes or neutron stars, whereas long GRBs (with a typical prompt emission of several tens of seconds) have their origin in asymmetric explosions of hypernovae. However, as of now, no GRB has been detected by CTA precursors like H.E.S.S., MAGIC or VERITAS. With CTA, its lower energy threshold and the ability of the LSTs to rotate within 20s to any point in the sky following a GRB alert, scientists hope to finally measure GRB signals on many occasions and shed light on the processes responsible for these mysteriously short but enormously luminous explosions. diff --git a/src/content/news/the-multiple-synergies-with-ctao.md b/src/content/news/the-multiple-synergies-with-ctao.md new file mode 100644 index 0000000..a4fd52d --- /dev/null +++ b/src/content/news/the-multiple-synergies-with-ctao.md @@ -0,0 +1,39 @@ +--- +title: "The Multiple Synergies with CTAO" +description: "Multi-wavelength and multi-messenger observations are increasingly becoming the norm in astronomy, and will be a central part of the CTAO observational program and strategy, essential for the achievement of its many science goals." +date: 2022-01-14 +category: news +author: CTAO +cover: /uploads/Crab.png +draft: false +--- + +Originally published in the [December 2021 issue of the CTA Newsletter.](https://mailchi.mp/5dc5e0991a84/cta-newsletter-may2021-english-8711433) + +Several decades of efforts and technological breakthroughs have pushed the observational boundaries of Astronomy, which has achieved the capability of ‘seeing’ photons of all existing wavelengths.

The main idea of the latter is, from one side to provide real-time information about the observing schedules and plans of CTAO, that can then be matched by other instruments in coordinated campaigns. On the other hand, an ecosystem of facilities needs to be set up to closely support CTAO’s regular observing programs. Efficient, real-time data and schedule sharing protocols and tools are fundamental ingredients for the success of the coordination. + +Real-time data sharing, and in particular the capability to trigger and follow-up external alerts, are also key to enable multi-wavelength and messenger science with CTAO, as well as the study of fast transients such as gamma-ray bursts. In the case of neutrinos and gravitational waves, for which event localization is uncertain, not only a rapid, but a coordinated multi-instrumental search for the counterpart source is necessary. Here, the interface with brokers, which receive and transmit tailor-made alert information integrated from multiple sources at once, will be crucial. + +In summary, CTAO will be a unique instrument for high-energy astrophysics, capable of detecting with unprecedented sensitivity and accuracy TeV gamma rays produced by the broadest variety of sources and regions of the Cosmos, and multi-instrument cooperation will significantly, and perhaps decisively, increase its science reach. diff --git a/src/content/news/thierry-stolarczyk-elected-cospokesperson-of-the-ctao-consortium.md b/src/content/news/thierry-stolarczyk-elected-cospokesperson-of-the-ctao-consortium.md new file mode 100644 index 0000000..c687ee3 --- /dev/null +++ b/src/content/news/thierry-stolarczyk-elected-cospokesperson-of-the-ctao-consortium.md @@ -0,0 +1,21 @@ +--- +title: "Dr. Thierry Stolarczyk Elected New Co-Spokesperson of the CTAO Consortium" +description: "On November 25, Dr. Thierry Stolarczyk was appointed as the new Co-Spokesperson of the CTAO Consortium.

In the not-too-distant future, CTA will measure these gamma rays with its improved sensitivity and will write down the chronicles of gamma-ray propagation on cosmological scales. + +![](/uploads/gpropa_100ppi-1024x507-1.png) + +***Fig. 1**: Cosmic journey of gamma rays from a distant galaxy down to the CTA Observatory. Some gamma rays produce electron-positron pairs when interacting with EBL photons (red). The pairs, deflected by the intergalactic magnetic field, scatter off CMB photons resulting in a gamma-ray halo (orange). Exotic processes such as Lorentz invariance violation (gray) or coupling to axion-like particles (light blue) could modify the absorption, resulting in characteristic spectral features.* + +Gamma rays are emitted in distant galaxies located billions of light years away. The chief foe that gamma rays face in the intergalactic medium is the army of lower-energy photons called the extragalactic background light (EBL). The EBL radiation spans the ultraviolet, optical and infrared bands and is created mainly by stars and dust in galaxies over the history of the Universe. EBL photons interact with gamma rays to generate pairs of electrons and positrons. This absorption, depicted in **Fig. 1** (red box), becomes stronger with increasing gamma-ray energy and source distance. By measuring it in gamma-ray spectra of extragalactic sources, CTA will probe with unrivaled accuracy the spectrum and evolution of the EBL, thereby unveiling the formation and evolution of dust and stars in galaxies. + +The electrons and positrons produced in the interaction with EBL photons do not reach Earth, however, they can scatter off photons of the cosmic microwave background (CMB). This transfers energy from the pairs to the CMB photons, transforming them to gamma rays with lower energies than that of the initial parent gamma ray, as shown in **Fig. 1** (orange box). Because electrons and positrons are charged particles, they are affected by the intergalactic magnetic field in cosmic voids, which deflects their trajectory on scales of millions of light years. This creates a diffuse gamma-ray halo around otherwise point-like sources. CTA will search for such halos, and possibly detect for the first time the elusive remnant of cosmic magnetism in the most rarefied corners of the Universe. + +In their struggle for survival, gamma rays could be helped by new processes, which lie beyond the standard models of particle physics and cosmology. The first is Lorentz invariance violation (LIV) at the Planck scale, the frontier of current physical theories. This process could shield gamma rays from interacting with the EBL, resulting in an unexpectedly large number of cosmic-trotters reaching Earth at the highest energies probed by CTA (**Fig. 1**, gray box). The second is a cloak called an axion-like particle. Gamma rays could put this cloak on within magnetic fields, effectively escaping interactions with the EBL. Cloaked-uncloaked oscillations (**Fig. 1**, light blue box) would result in larger-than-expected fluctuations in the gamma-ray spectra, which CTA will constrain with its excellent energy reconstruction. + +Gamma rays from extragalactic sources tell us the story of an epic cosmic journey, probing the very fabric and content of the Universe in large voids. A first report of the potential of CTA to constrain gamma-ray propagation can be found in [1], but the CTA Consortium is actively preparing the scientific machinery to greet cosmic-trotters and recount their odyssey. + +[1] Studying cosmological gamma-ray propagation with the Cherenkov Telescope Array, F.

She has always worked in the high-energy Astrophysics field, favoring Extragalactic Astronomy, studying sources such as galaxy clusters or black holes, including Ultraluminous X-ray sources and Active Galactic Nuclei (galaxies with a supermassive black hole at their centre that eats up the surrounding material, becoming very luminous). She has always believed in a multiwavelength approach to study astrophysical phenomena: by looking at things from different perspectives, at different frequencies and with different instruments, it is possible to learn much more from the Universe. Between 2013 and 2018, she was appointed member of the Steering Committee of the High Energy Division of the IAU. + +She has published more than 200 papers in scientific journals, and many outreach texts. She has delivered more than 200 conferences for schools or public lectures, and values the interaction with Universities and the young: she has held a few monographic courses at the universities in Milano and supervised Master and PhD thesis. Since 2010, she represents Italy in the ESO Science Outreach Network and, since 2020, she coordinates the outreach efforts for the national ASTRI project and serves as Country Representative of Italy at the CTA Outreach Committee. She also makes part of the editorial staff of EduINAF, the outreach magazine of INAF, and of astroEDU/it, the Italian version of the IAU portal of peer-reviewed astronomy education activities. + +## **Heide Costantini + +** + +Heide’s career started as a Nuclear Astrophysicist, studying nuclear reactions occurring in stars with the LUNA accelerator located at the underground laboratory of Gran Sasso in Italy. She got her PhD in Physics in 2003 at the University of Genova (Italy) and continued to work in nuclear astrophysics with a particular focus on the early and quiescent evolutionary stages of the life of the stars. After her postdoc at the University of Notre Dame in the US, she came back to Italy for a researcher position at the National Institute for Nuclear Physics (INFN). At that point, she started to get interested in the high-energy sky and, in particular, in the final evolution stages of a star that lead to the extreme energetic scenarios. She joined the ANTARES neutrino telescope experiment in 2007, for which she served as Calibration Coordinator for several years and studied the possibility of detecting a supernova neutrino. In 2010, she became Assistant Professor at the Aix-Marseille University (France) and joined the Cherenkov Telescope Array Consortium (CTAC), where she currently serves as the Galactic Working Group Co-Coordinator. Her work at CTAC focuses on the simulations for the Small-Sized and Medium-Sized Telescopes (SSTs and MSTs, respectively) and on the preparation of the hunt for PeVatrons, cosmic sources in our own Galaxy capable of accelerating charged particles up to energies of Peta-electronvolts (PeV) – thousands of trillions more energetic than the visible light! + +## **Judit Pérez + +** + +Judit is a last-year PhD candidate in the Instituto de Física Teórica (IFT) in Madrid (Spain). She graduated in Physics in Universidad de Valencia and moved to the IFT for her Master’s degree, where she joined the DArk Matter, AStroparticles and Cosmology (DAMASCO) group and started her PhD thesis. She specializes in gamma-ray searches of Dark Matter. From the most recent studies, we know that only 5% of the Universe is made of standard matter (atoms, protons, electrons…). The rest of the matter is invisible to us – that is why we named it Dark Matter. This mysterious Dark Matter usually only interacts leaving gravitational imprints, but there is a chance that from the collision of two Dark Matter particles some gamma rays emerge and arrive to our telescopes. Judit is member of the *Fermi*-LAT Collaboration and the Cherenkov Telescope Array Consortium (CTAC). Within the latter, as the Coordinator of the “Galaxy Clusters Task Force,” she has focused on studying galaxy clusters, the most massive objects in the Universe, as targets for searching Dark Matter. She is also working as the Coordinator of the “Dark Matter Tools Task Force” in software development for the analysis required to distinguish the gamma rays originated in the interaction of Dark Matter, from other gamma-ray sources. Judit is currently the Country Representative for Spain at the CTA Outreach Committee. “Women of CTA” is an annual event carried out under the Astrodiversity program, which gathers all those activities and initiatives organized or supported by CTAO within the inclusion and diversity framework.
