Formal confirmation will arrive once the project is officially withdrawn from Chile’s Environmental Assessment Service (SEA, in Spanish). + +Last year, ESO publicly [raised the alarm](https://www.eso.org/public/unitedkingdom/news/eso2501/?lang) about the threat that the INNA megaproject posed to the Paranal Observatory, a site renowned for having the world’s darkest and clearest skies for astronomy and the location of the [CTAO’s southern hemisphere array (CTAO-South)](https://www.ctao.org/emission-to-discovery/array-sites/ctao-south/). The project, proposed by AES Andes, a subsidiary of the U.S. power company AES Corporation, involved multiple energy and processing facilities spread over an area of more than 3,000 hectares, the size of a small city. Its planned location was situated just [a few kilometres from the Paranal telescopes](https://www.eso.org/public/unitedkingdom/images/INNA-map-EN/). An in-depth [technical analysis issued by ESO](https://www.eso.org/public/unitedkingdom/news/eso2506/) in March 2025 revealed that INNA’s impact would cause devastating and irreversible damage, particularly regarding light pollution, micro-vibrations, dust, and an increase of the air turbulence in the area. + +“While we await the company’s official withdrawal from SEA, we very much welcome this announcement. I would like to extend my deep and sincere appreciation to everyone who advocated for the protection of Paranal’s pristine skies,” says Stuart McMuldroch, CTAO Director General. “The CTAO remains committed to the preservation of dark and quiet skies, and we will continue collaborating with our hosting partners at ESO towards that goal.” + +Reflecting on the announced cancellation, ESO has also emphasised the broader lessons this situation provides regarding industrial projects near astronomical facilities. In [their press release](https://www.eso.org/public/unitedkingdom/news/eso2602/), they note that “the INNA case and its [proposed location](https://www.eso.org/public/images/INNA-map-EN/) highlight the urgent need to establish clear protection measures in the areas around astronomical observatories. Such measures are essential to allow astronomical observatories to continue operating.” Safeguarding this natural heritage is vital not only for future generations but also for the continued exploration of the Universe by cutting-edge facilities like the CTAO. + +Safeguarding this natural heritage is vital not only for future generations but also for the continued exploration of the Universe by cutting-edge facilities like the CTAO. diff --git a/src/content/news/camera-installation-marks-completion-of-lst-4-construction.md b/src/content/news/camera-installation-marks-completion-of-lst-4-construction.md new file mode 100644 index 0000000..2c1b21e --- /dev/null +++ b/src/content/news/camera-installation-marks-completion-of-lst-4-construction.md @@ -0,0 +1,21 @@ +--- +title: "Camera Installation Marks Completion of LST-4 Construction" +description: "On 22 May, the CTAO LST Collaboration reached another major milestone with the successful installation of the camera for LST-4, one of the three Large-Sized Telescopes (LSTs) under construction at the CTAO-North site on La Palma, Spain.…" +date: 2025-05-29 +category: news +author: CTAO +cover: /uploads/LST4Camera-1600x1200.jpg +draft: false +--- + +On 22 May, the [CTAO LST Collaboration](https://www.ctao.org/partners/in-kind-contributors/) reached another major milestone with the successful installation of the camera for LST-4, one of the three [Large-Sized Telescopes (LSTs)](https://www.ctao.org/emission-to-discovery/telescopes/lst/) under construction at the [CTAO-North](https://www.ctao.org/emission-to-discovery/array-sites/ctao-north/) site on La Palma, Spain. The camera installation represents the finalisation of the telescope’s construction and marks its transition to the commissioning phase. + +The camera installation was a complex and carefully coordinated procedure. After extensive preparation and alignment work, the nearly two-tonne camera was lifted by crane and secured onto the telescope structure with millimetre precision. The process involved teams from multiple institutions working in synchrony to ensure safety and protect the delicate instrumentation. + +The LST-4 camera features a wide field of view of 4,3 degrees and is composed of 1,855 photomultiplier tubes (PMTs). These highly sensitive light detectors convert the faint flashes of Cherenkov light—emitted when high-energy gamma rays interact with Earth’s atmosphere—into digital signals for scientific analysis. Each PMT is paired with a specially designed light guide that enhances efficiency by directing photons toward the detector. + +The camera’s internal electronics perform real-time signal analysis using advanced algorithms to identify the characteristic signatures of gamma-ray events. To capture the fleeting Cherenkov flashes associated with these, which last only a few nanoseconds or billionths of a second, the camera rapidly digitises and records the signals at gigahertz (GHz) sampling rates, processing up to a billion data points per second—orders of magnitude faster than conventional cameras. + +With the camera now in place, the LST-4 enters its commissioning phase, joining the LST-1, the prototype and the first telescope built on a CTAO site. During commissioning, the telescope will undergo rigorous testing to verify that it meets the CTAO’s scientific and technical requirements. In parallel, the LST Collaboration will continue the construction of the northern hemisphere site’s remaining two LSTs. + +Congratulations to all the teams in the LST Collaboration involved in this milestone! diff --git a/src/content/news/ctao-advances-towards-early-science-in-la-palma-as-lst-collaboration-announces-lst-subarray-inauguration.md b/src/content/news/ctao-advances-towards-early-science-in-la-palma-as-lst-collaboration-announces-lst-subarray-inauguration.md new file mode 100644 index 0000000..4ef780e --- /dev/null +++ b/src/content/news/ctao-advances-towards-early-science-in-la-palma-as-lst-collaboration-announces-lst-subarray-inauguration.md @@ -0,0 +1,151 @@ +--- +title: "The CTAO Advances Towards Early Science in La Palma as LST Collaboration Announces Inauguration of Large-Sized Telescope Sub-Array" +description: "(Versión en español abajo) La Palma, Spain, 27 May 2026 — The Cherenkov Telescope Array Observatory (CTAO), the future world’s largest and most powerful observatory for gamma-ray astronomy, continues its steady advance towards initial…" +date: 2026-05-27 +category: news +author: CTAO +cover: /uploads/DSC00216_1-1600x1069.jpg +draft: false +--- + +*(Versión en español abajo)* + +**La Palma, Spain, 27 May 2026 —** The Cherenkov Telescope Array Observatory (CTAO), the future world’s largest and most powerful observatory for gamma-ray astronomy, continues its steady advance towards initial operations. In a joint press conference held in Santa Cruz de La Palma, Canary Islands (Spain), representatives from the [CTAO Central Organisation](https://www.ctao.org/organisation/team/) (CTAO ERIC), the [CTAO LST Collaboration](https://www.ctao.org/partners/in-kind-contributors/), the Cabildo de La Palma, and the Instituto de Astrofísica de Canarias (IAC) came together to underscore the project’s advancement towards groundbreaking science, a progress marked by the upcoming inauguration of the four [Large-Sized Telescopes](https://www.ctao.org/emission-to-discovery/telescopes/lst/) (LSTs) on 15 October 2026 at the [CTAO-North](https://ctao.org/emission-to-discovery/array-sites/ctao-north/) site. + +The press event was held to coincide with the [CTAO ERIC Council](https://www.ctao.org/organisation/governance/) meeting on the island, which brought together delegates from more than 10 countries, including current and prospective CTAO ERIC members. It featured the Vice-President of the Cabildo de La Palma,  Juan Ramón Felipe San Antonio; the Director of the IAC, Valentín Martínez; the President of the CTAO ERIC Council, Francisco Colomer; the CTAO Project Scientist, Roberta Zanin; and the Chair of the LST Collaboration’s Steering Committee, Juan Cortina. + +The Vice President conveyed the greetings of the President of the Cabildo de La Palma, Sergio Rodríguez, and emphasised the absolute support of this administration for all the technological and scientific advancements taking place on La Palma through the Roque de los Muchachos Observatory (ORM, in Spanish), managed by the IAC. + +“It is an honour for our island to welcome the delegations and organisations from the countries of the CTAO. This meeting and these telescopes serve as confirmation that La Palma remains, in its own right, one of the science capitals of the world and one of the clearest windows for looking at the sky,” the Vice President stated, highlighting that “the sky over La Palma possesses exceptional conditions, protected by law, which have turned the ORM into a sanctuary for the study of the Universe.” Felipe San Antonio reiterated that “the deep-rooted connection the people of La Palma have with astronomy marks our very identity; we know how to look to the sky, as well as to the future.” + +For his part, the Director of the IAC, Valentín Martínez Pillet, stressed that the inauguration of these magnificent telescopes has been made possible thanks to inter-institutional collaboration and public support: “Hosting this meeting this week is confirmation that La Palma is a global benchmark in astrophysics and that the relationship between society and public administrations is a true model of success.” Specifically, he pointed out that “within this network, this is manifested in the support the Spanish government has given to the construction of these telescopes using FEDER (European Regional Development Fund) funds; coupled with the support of the Canary Islands Government and the Cabildo de La Palma.” + +“It is an absolute pleasure to gather our international delegations at the CTAO’s northern hemisphere site to witness our rapid advancement firsthand,” stated Francisco Colomer, President of the CTAO ERIC Council and Programs Director for the Spanish Deputy Directorate General for International Consortia, Organisms and Research Infrastructures. “As a European organisation, the CTAO has a truly global reach and support, while simultaneously generating a profound national and local impact. For Spain, hosting CTAO-North means spearheading a next-generation scientific endeavour and represents a major strategic commitment to the future of European astrophysics.” + +The construction of the Observatory is progressing at an exceptional pace. As the CTAO moves closer to initial operations and its first scientific results, the Central Organisation is rapidly expanding its workforce on the island. Since 2025 alone, the team has welcomed five new members, including several native La Palma professionals, with further employment opportunities planned for 2026 and 2027. + +“With the rapid advancement of the CTAO-North array, we are getting closer to opening a completely new window to the extreme Universe, giving us the ability to answer some of the most exciting questions in astronomy, such as the nature of dark matter,” highlighted Roberta Zanin, CTAO Project Scientist. “Moreover, we are committed to ensuring our La Palma neighbours are part of this endeavour through outreach and education programmes, so they can participate in and feel proud of the unprecedented science that will be conducted on the island.” + +As a testament to this commitment, this May alone the Observatory co-organised the [“Women of CTAO” event](https://www.ctao.org/news/ctao-and-cabildo-of-la-palma-organise-women-of-ctao-2026/) with the Cabildo de La Palma, held the international CTAO School, bringing doctoral students from across the globe to the island, and celebrated the successful internship of a local vocational training student. + +Alongside these community initiatives, the Observatory’s technological development continues to advance rapidly. A prime example is the work of the LST Collaboration, an international team of more than 500 members worldwide. The Collaboration is responsible for designing and building the LSTs, the largest of CTAO’s three classes of telescopes, and is now in the final stages of construction — a process that has also delivered a tangible socio-economic impact on La Palma, with over 30 local companies contracted during this phase. In October, the official inauguration of the four LSTs will take place at CTAO-North, a major announcement made during the press conference. + +“The upcoming inauguration is a historic milestone for the future of the Observatory, but especially for the LST Collaboration,” explained Juan Cortina, Chair of the Steering Committee of the LST Collaboration. “Our teams of scientists and engineers have worked tirelessly for years to reach this point. This celebration is the crowning achievement at the end of the construction phase, and we are thrilled to celebrate it together with partners from all over the world, including high-level institutional representatives and world-renowned scientists, such as Nobel Laureate Takaaki Kajita.” + +Importantly, the October inauguration is not the final step, but rather the gateway towards the realisation of the Observatory. Following this achievement, the LST Collaboration will continue working on technical tests required before the telescopes can be formally accepted and operated by the Central Organisation. Once accepted, they will be fully integrated within the CTAO-North array, which will also eventually feature [Medium-Sized Telescopes](https://www.ctao.org/emission-to-discovery/telescopes/mst/) (MSTs). + +Following the press conference, the international CTAO ERIC delegates will visit the Roque de los Muchachos Observatory to experience the project’s scale and impact in person. The visit to the CTAO-North site will be led by Patricia Márquez, CTAO-North Station Manager, whilst the detailed tour of the LSTs will be guided by Daniel Mazin, Project Manager of the LST Collaboration. + +With the imminent inauguration of the LSTs, organised by the LST Collaboration, and the steady expansion of the Central Organisation’s operations and team on the island, the CTAO stands on the threshold of a new era in gamma-ray astronomy. The path to unprecedented discoveries has officially begun, and La Palma is at the very heart of it. + +The CTAO (Cherenkov Telescope Array Observatory; www.ctao.org) will be the world’s largest and most powerful observatory for gamma-ray astronomy. 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: 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. + +The CTAO is a European Strategy Forum on Research Infrastructures (ESFRI) Landmark project, one of the “Magnificent Seven” of ASPERA’s European strategy for astroparticle physics and a top-ranked priority amongst new ground-based infrastructure projects for 2022-2035 in ASTRONET’s roadmap. + +To cover its broad energy range, 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’ (IAC’s) Roque de los Muchachos Observatory on La Palma (Spain), and CTAO-South in the southern hemisphere at 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 is a Big Data project. The Observatory will generate hundreds of petabytes (PB) of data in a year (~12 PB after compression). Based on its commitment to Open Science, the CTAO will be the first gamma-ray 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 Central Organisation (legally, the CTAO ERIC) is in charge of the construction and operation of the Observatory and manages the four sites. Thus, it is made up of the groups and people dedicated to the management and administration of the Observatory’s development and the overall project, science, computing or systems engineering activities, among others. The CTAO ERIC is financially supported by a growing list of countries and organisations. The CTAO ERIC members include Austria, Croatia, the Czech Republic, the European Southern Observatory (ESO), France, Germany, Italy, Poland, Slovenia, Spain, and Switzerland. Further countries — Australia, Brazil, Japan, South Africa, and the United States — are engaged in the process of joining the CTAO ERIC as Strategic Partners or Third Parties. + +This group works in close cooperation with partners from around the world toward the development of the Observatory. Major partners include In-Kind Contribution Collaborations (IKC) that are developing essential hardware and software, in addition to the CTAO Consortium, an international group of researchers who works on the scientific exploitation of the Observatory. Among the IKC is the CTAO LST Collaboration, in charge of developing the Large-Sized Telescopes (LSTs). + +When gamma rays interact with Earth’s atmosphere, they generate cascades of particles that produce Cherenkov light. Because lower-energy gamma rays create only small amounts of Cherenkov light, telescopes with large collection areas are needed to detect it. The LST, with its 23-meter diameter dish, will provide the CTAO’s unique sensitivity in the low-energy range between 20 GeV and 3 TeV. + +Despite standing 45 meters tall and weighing 100 tonnes, each LST can reposition to any point in the sky within 20 seconds. Both this rapid repositioning and the low-energy threshold of the LSTs are critical for the CTAO’s studies of galactic transients, high-redshift active galactic nuclei, and gamma-ray bursts. + +The CTAO LST Collaboration is responsible for designing and building these telescopes. It is made up of more than 500 scientists and engineers from 25 institutions across 11 countries: Brazil, Bulgaria, Croatia, Czech Republic, France, Germany, Italy, Japan, Poland, Spain and Switzerland. + +Alba Fernández-Barral, CTAO Chief Communications Officer + +[alba.fernandezbarral@cta-observatory.org](mailto:Alba.fernandezbarral@cta-observatory.org) (English, Spanish, Italian) + ++39-051-6357-270 + +For convenience, the links to the most up-to-date content are provided below.

En una rueda de prensa conjunta celebrada en Santa Cruz de La Palma, Islas Canarias (España), representantes de la [Organización Central del CTAO](https://www.ctao.org/es/organisation/team/) (CTAO ERIC), la [Colaboración LST del CTAO](https://www.ctao.org/es/partners/in-kind-contributors/), el Cabildo de La Palma y el Instituto de Astrofísica de Canarias (IAC) se reunieron para destacar el avance del proyecto hacia una ciencia pionera. Este progreso está marcado por la próxima inauguración de los [cuatro Large-Sized Telescopes](https://www.ctao.org/es/emission-to-discovery/telescopes/lst/) (LST, los telescopios grandes) el 15 de octubre de 2026 en el emplazamiento [CTAO-Norte](https://www.ctao.org/es/emission-to-discovery/array-sites/ctao-north/). + +El evento de prensa se celebró coincidiendo con la reunión del [Consejo del CTAO ERIC](https://www.ctao.org/es/organisation/governance/) en la isla, que agrupó a delegados de más de 10 países, incluyendo miembros actuales y potenciales del CTAO ERIC. Contó con la presencia del Vice-Presidente del Cabildo de La Palma, Juan Ramón Felipe San Antonio; el Director del IAC, Valentín Martínez; el Presidente del Consejo del CTAO ERIC, Francisco Colomer; la Responsable Científica del CTAO, Roberta Zanin; y el Presidente del Comité Directivo de la Colaboración LST, Juan Cortina. + +El vicepresidente trasladó el saludo del presidente del Cabildo de La Palma, Sergio Rodríguez, e insistió en el apoyo absoluto de esta administración a todos los avances tecnológicos y científicos que tienen lugar en La Palma a través del Observatorio del Roque de los Muchachos, del Instituto de Astrofísico de Canarias. “Para nuestra isla es un honor recibir a las delegaciones y organizaciones de los países del CTAO. Esta reunión y estos telescopios son la constatación de que La Palma sigue siendo, por derecho propio, una de las capitales mundiales de la ciencia y una de las ventanas más nítidas para mirar al cielo”, aseguró el vicepresidente y remarcó que “el cielo de La Palma posee unas condiciones excepcionales, protegidas por la Ley, que ha convertido al ORM en un santuario para el estudio del Universo”. Felipe San Antonio reiteró “el arraigo de los palmeros con la astronomía marca nuestra propia identidad, sabemos mirar al cielo y también al futuro”. + +Por su parte, el director del IAC, Valentín Martínez Pillet insistió en que la inauguración de estos magníficos telescopios es posible gracias a la colaboración interinstitucional y al apoyo social. “La celebración de esta reunión esta semana es la constatación de que La Palma es un referente mundial en Astrofísica y que la relación entre sociedad y administraciones es todo un modelo de éxito”, explicó Martínez Pillet. En concreto, expuso que “en esta red se manifiesta en el apoyo del Gobierno de España ha dado a la construcción de estos telescopios con fondos Feder; a lo que se suma el apoyo del Gobierno de Canarias y del Cabildo de La Palma”. + +“Es un absoluto placer reunir a nuestras delegaciones internacionales en el emplazamiento del hemisferio norte del CTAO para presenciar de primera mano nuestro rápido avance”, afirmó Francisco Colomer, Presidente del Consejo del CTAO ERIC y Director de Programas de la Subdirección General de Consorcios, Organismos e Infraestructuras de Investigación Internacionales de España. “Como organización europea, el CTAO tiene un alcance y un apoyo verdaderamente globales, al mismo tiempo que genera un profundo impacto nacional y local. Para España, albergar CTAO-Norte significa liderar un esfuerzo científico de próxima generación y representa un gran compromiso estratégico para el futuro de la astrofísica europea.” + +La construcción del Observatorio avanza a un ritmo excepcional. A medida que el CTAO se acerca a sus operaciones iniciales y a sus primeros resultados científicos, la Organización Central está ampliando rápidamente su plantilla en la isla. Desde 2025, el equipo ha dado la bienvenida a cinco nuevos miembros, incluyendo varios profesionales nativos de La Palma, con más oportunidades de empleo previstas para 2026 y 2027. + +“Con el rápido avance de CTAO-Norte, estamos cada vez más cerca de abrir una ventana completamente nueva al Universo extremo, brindándonos la capacidad de responder a algunas de las preguntas más emocionantes de la astronomía, como la naturaleza de la materia oscura”, destacó Roberta Zanin, Responsable Científica del CTAO. “Además, estamos comprometidos a garantizar que nuestros vecinos de La Palma formen parte de este progreso a través de programas de divulgación y educación, para que puedan participar y sentirse orgullosos de la ciencia sin precedentes que se llevará a cabo en la isla.” + +Como prueba de este compromiso, tan solo en este mes de mayo, el Observatorio coorganizó el [evento “Women of CTAO](https://www.ctao.org/news/ctao-and-cabildo-of-la-palma-organise-women-of-ctao-2026/)” con el Cabildo de La Palma, celebró la escuela internacional “CTAO School”, atrayendo a la isla a estudiantes de doctorado de todo el mundo, y celebró el éxito de las prácticas de una estudiante local de formación profesional. + +Paralelamente a estas iniciativas comunitarias, el desarrollo tecnológico del Observatorio sigue avanzando rápidamente. Un claro ejemplo es el trabajo de la Colaboración LST, un equipo internacional de más de 500 miembros de todo el mundo. La Colaboración es responsable de diseñar y construir los LST, el mayor de los tres tipos de telescopios del CTAO, que ahora se encuentran en las etapas finales de construcción — un proceso que también ha tenido un impacto socioeconómico tangible en La Palma, con la contratación de más de 30 empresas locales durante esta fase. En octubre tendrá lugar la inauguración oficial de los cuatro LST en CTAO-Norte, un importante anuncio realizado durante la conferencia de prensa. + +“La próxima inauguración es un hito histórico para el futuro del Observatorio, pero especialmente para la Colaboración LST”, explicó Juan Cortina, Presidente del Comité Directivo de la Colaboración LST. “Nuestros equipos de científicos e ingenieros han trabajado incansablemente durante años para llegar a este punto. Este logro culmina la fase de construcción y estamos encantados de celebrarlo junto a socios de todo el mundo, incluyendo representantes institucionales de alto nivel y científicos de renombre mundial, como el Premio Nobel Takaaki Kajita.” + +Es importante destacar que la inauguración de octubre no es el paso final, sino más bien un paso clave hacia la materialización del Observatorio. Tras este logro, la Colaboración LST continuará trabajando en las pruebas técnicas necesarias para que los telescopios puedan ser aceptados y operados oficialmente por la Organización Central. Una vez aceptados, se integrarán completamente en la red de CTAO-Norte, que en un futuro también contará con [Medium-Sized Telescopes](https://www.ctao.org/es/emission-to-discovery/telescopes/mst/) (MST, telescopios de tamaño medio). + +Tras la conferencia de prensa, las delegaciones internacionales del CTAO ERIC visitarán el Observatorio del Roque de los Muchachos para presenciar en persona la magnitud y el impacto del proyecto. La visita al emplazamiento CTAO-Norte será dirigida por Patricia Márquez, Responsable de la Estación CTAO-Norte, mientras que el recorrido detallado de los telescopios LST será guiado por Daniel Mazin, Gerente de Proyecto de la Colaboración LST. + +Con la inminente inauguración de los LST, organizada por la Colaboración LST, y la constante expansión de las operaciones y del equipo de la Organización Central en la isla, el CTAO se encuentra en el umbral de una nueva era en la astronomía de rayos gamma. El camino hacia descubrimientos sin precedentes ha comenzado oficialmente, y La Palma se encuentra en el corazón del mismo. + +El CTAO (Cherenkov Telescope Array Observatory; www.ctao.org) será el observatorio de astronomía de rayos gamma más grande y potente del mundo. La incomparable precisión y el amplio rango de energía del CTAO (20 GeV – 300 TeV) ayudarán a abordar algunas de las preguntas más emocionantes de la astrofísica, las cuales se agrupan en [tres temas principales](https://www.ctao.org/es/emission-to-discovery/science/study-themes/): + +-Comprender el origen y el papel de las partículas cósmicas relativistas. + +-Investigar entornos extremos, como los agujeros negros o las estrellas de neutrones. + +-Explorar las fronteras de la física, buscando materia oscura o desviaciones de la teoría de la relatividad de Einstein. + +Además, el CTAO desempeñará un papel clave en la astronomía multionda y multimensajero en las próximas décadas gracias a su mayor rendimiento, lo que le permitirá proporcionar información fundamental sobre los rayos gamma en la búsqueda por explorar los escenarios más extremos. + +El CTAO es un proyecto Landmark del Foro Estratégico Europeo sobre Infraestructuras de Investigación (ESFRI), uno de los “Siete Magníficos” de la estrategia europea de astrofísica de partículas de ASPERA, y una de las principales prioridades entre los nuevos proyectos de infraestructura terrestre para el período 2022-2035 en la hoja de ruta de ASTRONET. + +Para cubrir su amplio rango de energía, el CTAO utilizará [tres tipos de telescopios](https://www.ctao.org/es/emission-to-discovery/telescopes/): los Large-Sized Telescopes (LST, telescopios grandes), los Medium-Sized Telescopes (MST, telescopios de tamaño medio) y los Small-Sized Telescopes (SST, telescopios pequeños). + +Más de 60 telescopios se distribuirán entre los dos emplazamientos de telescopios: [CTAO-Norte](https://www.ctao.org/es/emission-to-discovery/array-sites/ctao-north/), ubicado en el hemisferio norte en el Observatorio del Roque de los Muchachos del Instituto de Astrofísica de Canarias (IAC) en La Palma (España), y [CTAO-Sur](https://www.ctao.org/es/emission-to-discovery/array-sites/ctao-south/), localizado en el hemisferio sur en el Observatorio Paranal del Observatorio Europeo Austral (ESO) en el Desierto de Atacama (Chile). La [sede central](https://www.ctao.org/es/organisation/facilities/) del CTAO está albergada por el Istituto Nazionale di Astrofisica (INAF) en Bolonia (Italia), y el [Centro de Gestión de Datos Científicos](https://www.ctao.org/es/organisation/facilities/) (SDMC) tiene su sede en el campus de Deutsches Elektronen-Synchrotron DESY en Zeuthen (Alemania). + +El CTAO es un [proyecto de Big Data.](https://www.ctao.org/es/emission-to-discovery/data-and-computing/) El Observatorio generará cientos de petabytes (PB) de datos al año (~12 PB tras la compresión). Basado en su compromiso con la Ciencia Abierta, el CTAO será el primer observatorio de rayos gamma terrestre en operar como un observatorio abierto e impulsado por propuestas de observación, proporcionando acceso público a sus datos científicos de alto nivel y productos de software. + +La Organización Central del CTAO (legalmente, el CTAO ERIC — Consorcio Europeo de Infraestructuras de Investigación) está a cargo de la construcción y operación del Observatorio, y gestiona las cuatro sedes. Así, está compuesta por los grupos y personas dedicados a la gestión y administración del desarrollo del Observatorio y de las actividades generales del proyecto, ciencia, computación o ingeniería de sistemas, entre otros. El CTAO ERIC cuenta con el respaldo financiero de una lista creciente de países y organizaciones. Los miembros del CTAO ERIC incluyen Alemania, Austria, Croacia, Eslovenia, España, Francia, Italia, el Observatorio Europeo Austral (ESO), Polonia, la República Checa y Suiza. Otros países —Australia, Brasil, Estados Unidos, Japón y Sudáfrica— están en proceso de unirse al CTAO ERIC como Socios Estratégicos o Terceras Partes. + +La Organización Central trabaja en estrecha cooperación con grupos socios de todo el mundo para el desarrollo del Observatorio. Los principales socios incluyen las Colaboraciones de Contribuciones en Especie (IKC, por sus siglas en inglés), que están desarrollando hardware y software esenciales, además del Consorcio CTAO, un grupo internacional de investigadores que trabaja en la explotación científica del Observatorio. Entre las IKC se encuentra la Colaboración LST del CTAO, encargada de desarrollar los LST. + +Cuando los [rayos gamma interactúan con la atmósfera terrestre](https://www.ctao.org/es/emission-to-discovery/science/how-ctao-works/), generan cascadas de partículas que producen luz Cherenkov. Debido a que los rayos gamma de menor energía crean solo pequeñas cantidades de luz Cherenkov, se necesitan telescopios con grandes áreas colectoras para detectarla. El LST, con su reflector de 23 metros de diámetro, proporcionará la sensibilidad única del CTAO en el rango de baja energía entre 20 GeV y 3 TeV. + +A pesar de sus 45 metros de altura y un peso de 100 toneladas, cada LST puede reposicionarse para apuntar a cualquier punto del cielo en tan solo 20 segundos. Tanto este rápido reposicionamiento como el bajo umbral de energía de los LST son críticos para los estudios del CTAO sobre eventos transitorios galácticos, núcleos activos de galaxias lejanas y estallidos de rayos gamma. + +La Colaboración LST del CTAO es responsable de diseñar y construir estos telescopios.

The capsule also included scientific items representing the ultimate goal of the telescopes now under construction: to advance our understanding of the Universe and expand human knowledge.  A commemorative plaque, set upon nearby stones, now marks the location of the buried capsule, beside the future telescope area. + +The CTAO, ESO, and Chile [signed agreements](https://www.ctao.org/news/final-agreements-signed-for-cta-southern-hemisphere-site-in-chile/) to have the CTAO southern array hosted at ESO’s Paranal Observatory in 2018. “Paranal is a unique place in the world to study the Universe,” highlighted Heinz during his welcoming speech at CTAO-South, explaining that Paranal is already home to ESO’s VLT — a key instrument in the discoveries recognised by the 2020 Nobel Prize in Physics — and the ESO’s Extremely Large Telescope that can be seen under construction in the distance from CTAO-South. “The Atacama Desert now welcomes another world-leading facility, and, in just one year, we expect to have here CTAO telescopes providing the first-ever observations of the gamma-ray sky from Chile.” + +To cover its broad energy range — from 20 GeV to 300 TeV, billions of times more energetic than visible light — the CTAO will employ three types of telescopes: the Large-Sized Telescopes (LSTs), the Medium-Sized Telescopes (MSTs), and the Small-Sized Telescopes (SSTs). The current configuration for CTAO-South includes more than 50 telescopes. To give the CTAO a complete view of the night sky, it will have two arrays of telescopes located in both the northern and southern hemispheres. The CTAO-South site in Chile, in tandem with the CTAO-North site in La Palma, Spain, will revolutionize our view of the high-energy Universe. + +With its unprecedented sensitivity and precision, the CTAO will help address some of the most fundamental questions in astrophysics. Its research will focus on three key areas: understanding the origin and role of relativistic cosmic particles; probing extreme environments such as black holes and neutron stars; and exploring the frontiers of physics by searching for dark matter and testing the limits of Einstein’s theory of relativity. In addition, the CTAO will play a key role in multi-wavelength and multi-messenger astronomy in the coming decades, providing essential gamma-ray data to complement observations across the entire electromagnetic spectrum and from other cosmic messengers such as neutrinos and gravitational waves. + +The CTAO is also a Big Data project, expected to generate hundreds of petabytes of data each year (around 12 PB after compression). Committed to the principles of Open Science, it will be the first gamma-ray observatory to operate as an open, proposal-driven facility, providing public access to its high-level scientific data and software products. Ten per cent of the observing time at CTAO-South is reserved for Chilean scientists, guaranteeing that Chile, as host country, gains direct scientific returns and strengthens its own research capacities through the Observatory’s presence. + +As construction begins in the Atacama Desert, today’s ceremony symbolises not only a technological milestone but also a shared commitment from Chile and the international community to push the boundaries of what we know about the most energetic and mysterious corners of the Cosmos. + +The [CTAO ERIC](https://www.ctao.org/organisation/team/) (also known as CTAO Central Organisation) is in charge of the construction and operation of the CTAO. Thus, it is made up of the groups and people dedicated to the management and administration of the Observatory’s development and the overall project, science, computing and systems engineering activities. The high-level organisational structure is broken into five main groups: Director’s Office, On-Site Construction, Project Office, Project Science Office, and Administration Office. The Central Organisation is responsible for managing the [CTAO’s four sites](https://www.ctao.org/organisation/facilities/): the Headquarters hosted by the Istituto Nazionale di Astrofisica (INAF) in Bologna (Italy), the Science Data Management Centre hosted by the Deutsches Elektronen-Synchrotron DESY in Zeuthen (Germany) and the [two telescope arrays](https://www.ctao.org/emission-to-discovery/array-sites/), CTAO-North at the Instituto de Astrofísica de Canarias’ (IAC’s) Roque de los Muchachos Observatory on La Palma (Spain), and CTAO-South, at the ESO’s Paranal Observatory in the Atacama Desert (Chile). + +This group works in close cooperation with [partners](https://www.ctao.org/partners/) from around the world toward the development of the Observatory. Major partners include In-Kind Contribution Collaborations that are developing essential hardware and software, in addition to the CTAO Consortium, an international group of researchers who works on the scientific exploitation of the Observatory. + +The [CTAO ERIC members](https://www.ctao.org/organisation/governance/) include Austria, Croatia, the Czech Republic, the European Southern Observatory (ESO), France, Germany, Italy, Poland, Slovenia, Spain, and Switzerland. Further countries — Australia, Brazil, Japan, South Africa, and the United States — are engaged in the process of joining the CTAO ERIC as Strategic Partners or Third Parties. + +The European Southern Observatory (ESO) enables scientists worldwide to discover the secrets of the Universe for the benefit of all. We design, build and operate world-class observatories on the ground — which astronomers use to tackle exciting questions and spread the fascination of astronomy — and promote international collaboration for astronomy. Established as an intergovernmental organisation in 1962, today ESO is supported by 16 Member States (Austria, Belgium, Czechia, Denmark, France, Finland, Germany, Ireland, Italy, the Netherlands, Poland, Portugal, Spain, Sweden, Switzerland and the United Kingdom), along with the host state of Chile and with Australia as a Strategic Partner. ESO’s headquarters and its visitor centre and planetarium, the ESO Supernova, are located close to Munich in Germany, while the Chilean Atacama Desert, a marvellous place with unique conditions to observe the sky, hosts our telescopes. ESO operates three observing sites: La Silla, Paranal and Chajnantor. At Paranal, ESO operates the Very Large Telescope and its Very Large Telescope Interferometer, as well as survey telescopes such as VISTA. Also at Paranal, ESO will host and operate the south array of the Cherenkov Telescope Array Observatory, the world’s largest and most sensitive gamma-ray observatory. Together with international partners, ESO operates ALMA on Chajnantor, a facility that observes the skies in the millimetre and submillimetre range. At Cerro Armazones, near Paranal, we are building “the world’s biggest eye on the sky” — ESO’s Extremely Large Telescope. From our offices in Santiago, Chile we support our operations in the country and engage with Chilean partners and society. + +### Dr. Alba Fernández-Barral, CTAO Chief Communications** **Officer + +Email: [alba.fernandezbarral@cta-observatory.org](mailto:alba.fernandezbarral@cta-observatory.org) + +Cell: +39-051-6357-270 + +(English, Spanish and Italian) + +### Bárbara Ferreira**, **ESO Media Manager + +Garching bei München, Germany + +Email: [press@eso.org](mailto:press@eso.org) + +Tel: +49 89 3200 6670 + +Cell: +49 151 241 664 00 + +### Francisco Rodríguez**, **ESO Head of Communication Chile + +Santiago, Chile + +Email: [francisco.rodriguez@eso.org](mailto:francisco.rodriguez@eso.org) + +Tel: +56 2 2463 3151 + +For convenience, the links to the most up-to-date content are provided below.

The results were published on 23 July by the renowned journal [The Astrophysical Journal Letters (ApJ Letters)](https://iopscience.iop.org/article/10.3847/2041-8213/ade4cf). The publication presents in-depth observations conducted in 2022 with the [Large-Sized Telescope (LST](https://www.ctao.org/emission-to-discovery/telescopes/lst/)) prototype, the LST-1, during its commissioning phase at the Roque de los Muchachos Observatory on the [CTAO-North](https://www.ctao.org/emission-to-discovery/array-sites/ctao-north/) site in La Palma, Spain. The observations revealed a hint of an excess in the gamma-ray flux, which help provide new insights into the enigmatic and complex nature of GRBs at very high energies. The results support theoretical models in which these bursts generate structured, multi-layered jets where particles are accelerated. + +GRBs are among the Universe’s most powerful phenomena, releasing in just seconds as much energy as the Sun emits over its entire lifetime. As their name suggests, they burst over a brief, prompt phase, lasting seconds to minutes, and then are followed by an afterglow that can fade over hours to months. GRBs are classified as short or long based on the duration of the burst: long GRBs are thought to be linked to exceptionally bright supernovae, while short GRBs likely result from neutron star collisions. Despite their intense brightness, these extragalactic sources are challenging to detect at the highest energies because the gamma rays they emit weaken over the vast distances they travel, as well as due to their transient nature. + +On 9 October 2022, space-based observatories, such as NASA’s *Fermi* and Swift satellites, detected an extremely bright long GRB, named GRB 221009A. Dubbed the “BOAT” (“Brightest Of All Time”), the burst was so intense that it saturated multiple instruments observing it, and triggered follow-up observations across the globe. + +The LST-1 telescope, located at the CTAO’s northern array site in La Palma (Canary Islands, Spain), began observing the event just 1.33 days after the initial explosion. Spanning over 20 days after the GRB onset, the observations with the LST-1 enabled the LST Collaboration to identify an excess of gamma rays. While this excess did not reach the threshold required in the field to claim a formal detection, it allowed the team to establish very constrained upper limits on the very high-energy gamma-ray flux emitted by the source. Thus, these results mark an important step toward disentangling between competing theoretical models. + +GRBs are believed to involve ultra-fast jets of plasma ejected either from a black hole, remanent of long GRBs, or from the merging of neutron stars, in short GRBs. However, the exact process behind jet formation remains a major mystery. The LST-1 data support the theory that GRB 221009A was powered by a complex, structured jet: a narrow, ultra-fast core surrounded by a wider, slower-moving sheath of material. This challenges the simpler “top-hat” jet commonly used in earlier studies and offers new insights into jet formation mechanisms and the nature of the central engine. + +Notably, the recorded data include observations made under very bright moonlight conditions, which poses a significant challenge for Cherenkov telescopes due to their sensitive cameras. The full moon in the hours following the burst prevented rapid follow-up by other Cherenkov telescopes, but the technical solutions developed by the LST Collaboration made it possible for the LST-1 to be the first one to observe the source in the very high-energy gamma-ray regime. This marks the first time that the LST-1 has collected data under such challenging conditions, opening new possibilities for observing transient cosmic phenomena even during very bright moon nights. + +These results demonstrate the power of the CTAO’s next-generation telescopes to explore the very high-energy Universe, ushering in a new era where researchers can probe the inner workings of cosmic sources in unprecedented detail. As the CTAO continues to expand—three more LSTs are under development by the LST Collaboration on the same site and construction is beginning on the CTAO-South site in Chile—intermediate configuration arrays will soon be operational in both hemispheres. With an unprecedented sensitivity, these subsets of telescopes will already enhance our ability to study GRBs and other extreme phenomena. Complementarily, the successful deployment of alert handlers is allowing automatic responses, further reducing the follow-up reaction times for transient events. + +The [CTAO LST Collaboration](https://www.ctao.org/partners/in-kind-contributors/) is an In-Kind Contributor (IKC) for the CTAO, in charge of building the [Large-Sized Telescopes (LSTs)](https://www.ctao.org/emission-to-discovery/telescopes/lst/). The collaboration is made up of more than 400 scientists and engineers from 67 different institutes across 11 countries: Brazil, Bulgaria, Croatia, Czech Republic, France, Germany, Italy, Japan, Poland, Spain and Switzerland. + +The [Large-Sized Telescopes (LSTs)](https://www.ctao.org/emission-to-discovery/telescopes/lst/) are one of the [three types of telescopes](https://www.ctao.org/emission-to-discovery/telescopes/) that the CTAO will use to cover its broad energy range, from 20 GeV to 300 TeV. When gamma rays interact with Earth’s atmosphere, they generate cascades of particles that produce [Cherenkov light](https://www.ctao.org/emission-to-discovery/science/how-ctao-works/). Because lower-energy gamma rays create only small amounts of Cherenkov light, telescopes with large collection areas are needed to detect it. The LST, with its 23-meter diameter dish, will provide the CTAO’s unique sensitivity in the low-energy range between 20 and 150 GeV. + +Despite standing 45 meters tall and weighing 100 tonnes, each LST can reposition to any point in the sky within 20 seconds. Both this rapid repositioning and the low-energy threshold of the LSTs are critical for the CTAO’s studies of galactic transients, high-redshift active galactic nuclei, and gamma-ray bursts. + +The [CTAO LST Collaboration](https://www.ctao.org/partners/in-kind-contributors/), responsible for designing and building these telescopes, is making rapid progress on the [CTAO-North](https://www.ctao.org/emission-to-discovery/array-sites/ctao-north/) site in La Palma, Spain.

Since atmospheric conditions affect how this light reaches the telescopes, the atmosphere must be continuously monitored to meet the CTAO’s demanding accuracy requirements. + +As part of this monitoring strategy, researchers from In-Kind Contribution teams in Spain (IFAE and UAB/CERES-IEEC), Slovenia (University of Nova Gorica), and Italy (INFN-Padova), in collaboration with members from the CTAO Central Organisation, developed the pBRL as an atmospheric calibration pathfinder device. + +LIDAR (Light Detection and Ranging) systems use a laser and telescope to probe the atmosphere. The laser sends short pulses of light upward, which are scattered by aerosols and molecules. The telescope collects the returning light, and by measuring the delay, researchers can determine the amount and type of atmospheric content at different altitudes. This information is then used to correct atmospheric effects in CTAO observations. + +What sets the pBRL apart from other LIDAR systems is its large mirror of 1,8 metres diameter, dual-laser configuration and uniquely designed detection units. The pBRL emits two laser beams at different wavelengths simultaneously, and the returning signal is split into four distinct wavelength channels. One of these channels isolates the Raman-scattered light — light that has interacted with nitrogen molecules in the air, causing its wavelength to shift slightly. This advanced setup enables researchers to extract much more detailed information about the atmosphere, including the identification of specific gases and aerosol types. + +The prototype [was installed on the CTAO-North site](https://www.ctao.org/news/lidar-pathfinder-cta-north-first-light/) in La Palma, Spain, in 2021 for a one-year testing period. With the data collected, the pBRL team assessed its performance, design, data analysis and software. Their findings are detailed in two scientific papers published this year: [the first article](https://www.mdpi.com/2072-4292/17/6/1074) focuses on the system design and technical performance, while [the second](https://www.mdpi.com/2072-4292/17/11/1815) presents a newly developed data analysis software suite and results from the measurement campaigns. The results also include an assessment of the pBRL’s performance under challenging atmospheric conditions caused by dust from the  eruption of the Tajogaite volcano in La Palma in 2021, providing valuable data that helped validate the system’s reliability. + +With the evaluation of the pathfinder now complete, the teams are incorporating the lessons learned into the final design of the Barcelona Raman LIDAR system. These improvements will ensure even greater robustness and accuracy for long-term operation, supporting the Observatory’s goal of delivering high-quality gamma-ray data under different atmospheric conditions. diff --git a/src/content/news/shotaro-abe-wins-first-werner-hofmann-scientific-award.md b/src/content/news/shotaro-abe-wins-first-werner-hofmann-scientific-award.md new file mode 100644 index 0000000..c26b31a --- /dev/null +++ b/src/content/news/shotaro-abe-wins-first-werner-hofmann-scientific-award.md @@ -0,0 +1,21 @@ +--- +title: "Shotaro Abe Wins First Werner Hofmann Scientific Award" +description: "On 14 October, the inaugural Werner Hofmann Scientific Award was presented at the CTAO Construction Meeting that is taking place this week at the CTAO Science Data Management Centre (SDMC) in Zeuthen, Germany.

Following a rigorous nomination and review process by an international panel of experts, the award was given to Shotaro Abe, a researcher at the Institute for Cosmic Ray Research (ICRR) and University of Tokyo, for his groundbreaking work on dark matter and PeVatrons. Abe received the award from Prof. Werner Hofmann, which included a trophy, a monetary prize, and the opportunity to present his research to an audience of CTAO experts from around the world. + +Abe’s doctoral studies, completed this past March, focused on two major mysteries in astrophysics: dark matter, the invisible form of matter that makes up around 25% of the Universe but whose nature remains unknown, and PeVatrons, cosmic accelerators capable of producing particles at petaelectronvolt (PeV) energies, far beyond the reach of human-made accelerators. + +To tackle these challenges, Abe developed innovative large-zenith-angle observation techniques, which involve observing sources low on the horizon. These were long considered impractical because the atmosphere absorbs more gamma rays at such angles, and the telescope’s response strongly varies, creating complex uncertainties. As a member of the [CTAO LST Collaboration](https://www.ctao.org/partners/in-kind-contributors/), Abe led an international team working with the [Large-Sized Telescope (LST)](https://www.ctao.org/emission-to-discovery/telescopes/lst/) prototype, LST-1, located on [CTAO-North](https://www.ctao.org/emission-to-discovery/array-sites/ctao-north/), and through careful calibration and analysis, he was able to turn these challenges into an advantage, extending LST-1’s sensitivity above 20 TeV with just 40 hours of observation. + +Alongside these technical achievements, Abe published influential scientific studies. For dark matter, he investigated the Galactic Centre to search for gamma rays from the annihilation of Higgsino, a dark matter candidate. Using telescope simulations, he showed that CTAO-North could detect this elusive particle by 2030, demonstrating that such searches are feasible from the northern hemisphere and not only from the south, as previously thought. In his PeVatron studies, Abe applied wide-field analyses methods, which examine a large region of the sky simultaneously, revealing subtle variations in the gamma-ray spectrum across the Galactic Centre and providing new insights into the origin and structure of extreme cosmic accelerators. + +Launched in early 2025 by the [CTAO Central Organisation](https://www.ctao.org/organisation/), the Werner Hofmann Scientific Award recognises early-career researchers who make significant contributions to gamma-ray astronomy and the CTAO through innovative research, technical advances, or emerging scientific leadership. Named after Prof. Hofmann, a pioneering figure in the field, the award honours his lasting impact on the vision and design of the CTAO. The evaluation committee for the 2025 edition brought together experts from different countries and fields, including Hofmann, to select the winner: Catherine Boisson (Observatoire de Paris, France), Rubén López-Coto (Instituto de Astrofísica de Andalucía, IAA-CSIC, Spain), Alison Mitchell (Friedrich-Alexander-Universität Erlangen-Nürnberg, Germany), Masahiro Teshima (Max Planck Institut für Physik, MPI, and ICRR, Japan), and Roberta Zanin (CTAO Project Scientist). + +Congratulations to Shotaro Abe on this well-deserved recognition! diff --git a/src/content/news/small-sized-telescopes-pass-readiness-review-to-proceed-to-factory-testing.md b/src/content/news/small-sized-telescopes-pass-readiness-review-to-proceed-to-factory-testing.md new file mode 100644 index 0000000..371c784 --- /dev/null +++ b/src/content/news/small-sized-telescopes-pass-readiness-review-to-proceed-to-factory-testing.md @@ -0,0 +1,25 @@ +--- +title: "Small-Sized Telescopes Pass Readiness Review to Proceed to Factory Testing" +description: "On 2–3 December, the CTAO Central Organisation’s Telescope team visited the facilities of the Italian company Dal Ben, located in the Veneto region, to conduct the Test Readiness Review (TRR) for the electromechanical structure of the…" +date: 2025-12-17 +category: news +author: CTAO +cover: /uploads/SST_TRR_1125-1600x1133.jpg +draft: false +--- + +On 2–3 December, the [CTAO Central Organisation’s](https://www.ctao.org/organisation/team/) Telescope team visited the facilities of the Italian company Dal Ben, located in the Veneto region, to conduct the Test Readiness Review (TRR) for the electromechanical structure of the [Small-Sized Telescope](https://www.ctao.org/emission-to-discovery/telescopes/sst/) (SST). After the CTAO [SST Collaboration](https://www.ctao.org/partners/in-kind-contributors/) completed the integration of the first SST telescope at the facility, which includes a mechanical and electrical model of the camera, this review represents a key milestone, determining the telescope’s readiness for the start of factory testing. + +With the positive TRR outcome, the SST Collaboration team immediately proceeded to factory testing, which will run until the end of January 2026.

As the central system that will eventually send commands to operate both CTAO telescope arrays, conducting integration tests between ACADA and the telescope is a critical pre-shipment milestone to minimise potential compatibility risks before the [SSTs](https://www.ctao.org/emission-to-discovery/telescopes/sst/) are delivered to the remote [CTAO-South](https://www.ctao.org/emission-to-discovery/array-sites/ctao-south/) site in Chile. + +The rapid success of these integration tests was the direct result of exceptional synergy between the two groups. In the weeks leading up to the campaign, the SST Collaboration and the Central Organisation’s ACADA, Telescope, and System Integration teams worked together closely to lay the groundwork for the software deployment. This joint preparation paid off during the on-site work at the facilities of Dal Ben S.p.A., the company in charge of the mass production of the SST structures, in San Stino di Livenza, Italy. It took barely two days of joint, hands-on work at the factory for these two highly complex systems to successfully communicate with one another. + +“Integrating the array control software with the instrument control software is a challenging transition for any observatory,” says Dominik Neise, ACADA Lead Developer. “The fact that the system responded accurately to our commands almost immediately significantly de-risks our schedule. We resolved a few minor issues on the spot, proving that our teams are fully aligned and capable of troubleshooting together under real-world conditions.” + +During the tests, ACADA successfully executed commands instructing the telescope to perform repositioning and source tracking, whilst also retrieving monitoring data, such as temperature, from the sensors. Moreover, because only the mechanical structure is currently available at the Dal Ben S.p.A. factory, the SST camera team developed a simulation of the camera instrument. This allowed the teams to run the camera’s integration tests with ACADA, as well, ensuring a highly realistic, end-to-end testing environment. + +“What is particularly encouraging is how smoothly the system behaved once connected to the real telescope structure,” says Vito Conforti, SST Telescope Control Software Lead and ACADA Release Manager. “This achievement reflects the extensive development and validation activities carried out across all Telescope Control Software subsystems, and the strong collaboration within the SST teams, from structure to camera, as well as with ACADA. It provides clear evidence that the adopted approach is robust and that the system is well prepared for the next phases of integration.” + +The CTAO SST Collaboration is an In-Kind Contribution team tasked with developing and building the SSTs. Ultimately, 37 of these telescopes will be integrated into the CTAO-South array in Chile to study the highest-energy Universe. Following their installation and commissioning, they will be formally accepted by the Central Organisation for operation as an integral part of the Observatory. + +With this first round of command execution and data exchange completed successfully, the teams will return to the Dal Ben S.p.A. factory in early May for the final phase of the testing campaign.

In preparation for the operation of this “sub-array” of telescopes, the Central Organisation has been rapidly growing its team on site to ease the transition and ensure early science can begin, even as the rest of the array is under construction. + +“With the start of the construction phase, the CTAO has become an active research infrastructure within the CCI community,” says Roberta Zanin, CTAO Project Scientist. “The CTAO is strengthening its engagement with the other facilities at the ORM, fostering synergies that will enhance scientific exploitation and maximise the observatory’s scientific impact.” + +The CTAO Central Organisation was delighted to co-host the event alongside INAF, the University of Bologna, and the Galileo National Telescope. Each host gave participants the opportunity to visit a special astronomical site in and around Bologna. The CTAO provided access to its offices at its headquarters, while INAF organized a guided tour of the Medicina Radio Observatory, home to the historic Northern Cross Radio Telescope. The University of Bologna hosted participants at the Accademia delle Scienze, located within the university museum complex, which also includes La Specola Museum, the city’s astronomical museum. At La Specola, participants also learned about the pioneering work of Guido Horn d’Arturo, whose innovative segmented mirror designs anticipated technologies now used in modern observatories such as the CTAO. + +“There is tremendous excitement surrounding the upcoming operations of the CTAO-North array and the groundbreaking science it will deliver,” said McMuldroch. “We are grateful to contribute to this committee and to strengthen collaboration with neighbouring observatories as we prepare for what lies ahead.” diff --git a/src/content/news/the-ctao-engages-with-slovenian-industry-at-big-science-business-meeting.md b/src/content/news/the-ctao-engages-with-slovenian-industry-at-big-science-business-meeting.md new file mode 100644 index 0000000..c6f6958 --- /dev/null +++ b/src/content/news/the-ctao-engages-with-slovenian-industry-at-big-science-business-meeting.md @@ -0,0 +1,19 @@ +--- +title: "The CTAO Engages with Slovenian Industry at Big Science Business Meeting" +description: "On 3 February, the Chamber of Commerce and Industry of Slovenia (GZS) hosted the annual Big Science business meeting, an event designed to connect national companies and institutions with leading research organisations worldwide.

The Council is the governing body of the CTAO ERIC and includes delegates from Austria, Croatia, the Czech Republic, the European Southern Observatory (ESO), France, Germany, Italy, Poland, Slovenia, Spain, and Switzerland. Further countries—Australia, Brazil, Japan, South Africa, and the United States—are currently engaged in the process of joining as Strategic Partners or Third Parties. + +Delegates representing these nations, alongside members of the [CTAO Central Organisation (legally, CTAO ERIC)](https://www.ctao.org/organisation/team/), travelled to the island or connected remotely to discuss the Observatory’s progress and strategic direction. Prior to the formal meeting sessions, the Council undertook its first official tour of the [CTAO-North site](https://www.ctao.org/emission-to-discovery/array-sites/ctao-north/), which currently hosts four Large-Sized Telescopes (LSTs) at various stages of development by the [CTAO LST Collaboration](https://www.ctao.org/partners/in-kind-contributors/). + +### Arrival and Institutional Welcome + +Ascending to 2,200 metres above sea level to the Roque de los Muchachos Observatory (ORM), home of CTAO-North, visitors are greeted by the impressive LSTs standing tall against the landscape. + +The delegates were officially welcomed to the ORM by Valentín Martínez, Director of the Instituto de Astrofísica de Canarias (IAC), CTAO hosting partner. He provided an overview of the ORM’s evolution and the CTAO’s neighbouring instruments, including the Gran Telescopio Canarias (GTC), which some delegates also had the opportunity to tour. + +Standing before the towering telescopes, the group was greeted by Patricia Márquez, CTAO-North Station Manager. She detailed the project’s progress on the island, highlighting the expansion of the sea-level office, staff growth, and the future on-site operations building. Further enriching the welcome, Ramón García, Principal Investigator of the IAC’s gamma-ray group, shared insights into the [groundbreaking science](https://www.ctao.org/emission-to-discovery/science/study-themes/) the Cherenkov telescopes can deliver. + +### Up Close with the Telescopes + +While observing the telescopes from a distance offers a magnificent overview of the array, the delegates were invited to step inside and explore two of them up close. Divided into groups, they visited LST-1, the prototype undergoing commissioning since 2018, and LST-4, which recently completed its construction phase with the installation of its camera. + +At LST-1, delegates climbed the tower that supports the camera whilst in its resting position. From this vantage point, the true scale of the camera became apparent; together with its exterior framework, it measures a massive 3×3 metres. + +Guided by Oscar Blanch, Technical Coordinator of the LST Collaboration, the group opened the rear of the camera to reveal the back-end systems responsible for the evaluation and recording of gamma-ray events. From this elevated platform, they also had a direct view of the mirrors and the central calibration system located in the heart of the reflector. + +Additionally, Alice Donini, Technical On-Site Coordinator of the LST Collaboration, showcased the control monitors currently used for the telescope’s commissioning. By keeping a close eye on individual subsystems and meteorological conditions, operators manage the observations that test the telescopes. Ultimately, all Observatory operations will be managed from the future on-site operations building. + +The visit to LST-4 provided a deeper dive into the telescopes’ structural engineering. Walking through the framework, guided by Daniel Mazin, LST Project Manager, delegates closely examined the tubular carbon fibre structure. This design not only supports the 100-tonne telescope but also keeps it remarkably lightweight, enabling it to reposition to any point in the sky in under 20 seconds. This structure represents a true engineering milestone: the segments are joined by over 600 unique nodes, perfectly shaping the reflector. + +Back on the ground, Juan Cortina, Chair of the LST Collaboration Steering Committee, showed the delegates spare mirrors stored in the LST-4 work area, allowing them to appreciate their impressive size of around two square metres. During the day, the mirrors installed on the telescopes are intentionally misaligned for safety reasons. However, before observations begin, the telescope is calibrated, and the mirrors are adjusted with micron-level precision to ensure the reflector perfectly focuses Cherenkov light into the camera, which is suspended 28 metres away by an arch and carbon-fibre tension rods. + +The continuous progress of these four telescopes is a testament to the hard work of the LST Collaboration. Capitalising on this momentum, a press conference held prior to the visit—featuring the LST Collaboration alongside the CTAO Central Organisation, the Cabildo de La Palma, and the IAC—[announced that the official inauguration of the LST sub-array](https://www.ctao.org/news/ctao-advances-towards-early-science-in-la-palma-as-lst-collaboration-announces-lst-subarray-inauguration/) will take place on 15 October, with special guests like Prof. Takaaki Kajita, Nobel Laureate in Physics. + +### Looking Ahead + +This visit marked not only the CTAO ERIC Council’s first official tour of the CTAO-North site but also an invaluable opportunity to witness firsthand the development of what will become the world’s most powerful gamma-ray observatory—a growing international effort made possible by the unwavering support of the CTAO ERIC Council member countries and organisations. + +An exciting path lies ahead. Following the inauguration, the LST Collaboration will continue the commissioning required before the telescopes can be officially accepted and operated by the CTAO Central Organisation, and the site will soon welcome the first Medium-Sized Telescope (MST). + +As the Central Organisation’s dedicated team and daily operations continue to expand on La Palma, we are getting ready for the initial operations, thus beginning to unlock the high-energy Universe. diff --git a/src/content/news/the-ctao-joins-the-iac-in-celebrating-its-40th-anniversary.md b/src/content/news/the-ctao-joins-the-iac-in-celebrating-its-40th-anniversary.md new file mode 100644 index 0000000..7e5c300 --- /dev/null +++ b/src/content/news/the-ctao-joins-the-iac-in-celebrating-its-40th-anniversary.md @@ -0,0 +1,41 @@ +--- +title: "The CTAO Joins the IAC in Celebrating Its 40th Anniversary" +description: "The Instituto de Astrofísica de Canarias (IAC), hosting partner of the CTAO, celebrated its 40th anniversary on 24 July 2025.

The mirror installation process, which began on 31 March, is a meticulous and collaborative effort involving multiple research institutions and companies. Each mirror is installed individually, requiring careful alignment and coordination. + +Mirrors are a critical component of Cherenkov telescopes, as they reflect the faint Cherenkov light produced when high-energy gamma rays interact with Earth’s atmosphere onto the telescope’s camera. In the case of the LSTs—the largest class of CTAO telescopes—198 hexagonal mirrors are required to cover its massive 400 m² reflective surface (the equivalent of around two tennis courts). + +Each mirror facet is coated with a multi-layer material designed to maximise reflectivity while ensuring long-term durability. Mounted on a lightweight carbon-fiber structure, each mirror segment weighs just 50 kg. This balance between strength and weight allows the LST to maintain structural integrity while enabling rapid repositioning to capture brief, transient gamma-ray events. + +The mirrors are positioned 28 metres from the camera, forming a 23-metre diameter parabolic dish. This design creates a so-called isochronous surface, meaning that the reflected light coming from any point of the large dish arrives at the camera simultaneously—an essential feature for accurately reconstructing the particle showers caused by gamma-ray interactions and determining their origin in the sky. + +With the installation now complete, the LST Collaboration will proceed to equip each mirror with cables for precision actuators as part of the Active Mirror Control system. This system enables micron-level adjustments to each mirror, ensuring optimal pointing accuracy and observational performance. + +The LST Collaboration will continue working on the LST-3, along with the other two LSTs currently under construction at the site, with the next major milestone being the installation of one of the cameras. All three telescopes are expected to be completed by spring next year, joining the LST-1, inaugurated in 2018 and currently under commissioning. + +The companies and research groups from the LST Collaboration involved in the mirror installation are: CaSana (company and main work centre), Institute of Physics of the Czech Academy of Sciences (FZU), ICRR, University of Tokyo, Chiba University and shifters from INFN.

With a quarter of its full array of pixels installed, the camera recorded its first signals from the night sky just hours after installation, marking an important technical step in the SST’s ongoing development. + +When high-energy gamma rays interact with the Earth’s atmosphere, they produce a brief, faint flash of bluish [Cherenkov light](https://www.ctao.org/emission-to-discovery/science/how-ctao-works/), lasting only a few nanoseconds (billionths of a second). Though invisible to the naked eye, this light can be captured by the ultra-fast, sensitive cameras of the CTAO telescopes. Depending on the telescope type, the CTAO uses different kinds of cameras, but all of them are composed of hundreds of detectors, or pixels. + +For the SST, the smallest of the CTAO’s [three telescope types](https://www.ctao.org/emission-to-discovery/telescopes/), the camera consists of 2048 silicon photomultipliers (SiPMs) that convert Cherenkov light into digital signals, enabling scientists to analyse and study gamma rays. As a complex and critical component, the camera must be rigorously tested at various stages of its development. + +*ASTRI-2 telescope in Tenerife with the camera prototype installed.

To evaluate its performance, the camera, equipped with a quarter of the total 2048 SiPMs, was installed on the ASTRI-2 telescope in Tenerife, in a collaborative effort with the [ASTRI Mini-Array project](http://www.astri.inaf.it/). ASTRI was designed not only as a stand-alone experiment, but also as a pathfinder for the SST. + +Within hours of installation, the prototype camera successfully recorded signals from the night sky, including muon rings and cosmic-ray showers moving across the camera in the nanosecond timescale. These tests are part of the planned prototyping phase, and the excellent results further validate the expectations of strong performance from the final camera. *Left: The left panel shows a Cherenkov cascade detected by the QCAMi, while the right panel shows a muon ring.

Standing nine metres tall and weighing 17,5 tonnes, each SST features a compact dual-mirror Schwarzschild–Couder optical system. This system includes a segmented 4,3-metre primary mirror made up of 18 hexagonal elements, which reflects light onto a 1,8-metre monolithic secondary mirror. This dual-mirror design provides excellent spatial resolution across a wide field of view while maintaining a compact focal length ideal for lightweight cameras. + +The SST Collaboration is an [In-Kind Contribution team](https://www.ctao.org/partners/in-kind-contributors/) for the CTAO, responsible for developing the SSTs. It is coordinated by the INAF institute from Italy and comprises research institutions and universities from Australia, Brazil, France, Germany, Italy, Japan, the Netherlands, Switzerland, and UK. The SST cameras will be built by a team of institutes from Germany, the Netherlands, Japan, UK, and Australia, led by the Max-Planck-Institute für Kernphysik in Heidelberg, Germany. + +The Italian participation in this campaign was supported by the Next Generation EU funds within the National Recovery and Resilience Plan (PNRR), Mission 4 – Education and Research, Component 2 – From Research to Business (M4C2), Investment Line 3.1 – Strengthening and creation of Research Infrastructures, Project IR0000012 – “CTA+ – Cherenkov Telescope Array Plus.”
