Consultation communautaire sur les installations VLOT/OIR

assemblées publiques et sondage à venir

Chers collègues de la CASCA,

Au nom de la CASCA, nous vous invitons à participer à une importante consultation communautaire concernant l’accès futur du Canada aux installations de télescopes géants optiques/infrarouges (VLOT).

Le Plan à long terme canadien (LRP) et son évaluation à mi-parcours (MTR) ont constamment identifié l’accès à un VLOT comme une priorité nationale majeure. Depuis plus de deux décennies, le Thirty Meter Telescope est considéré comme la principale voie pour atteindre cet objectif. Toutefois, des développements récents – notamment des changements proposés concernant le site du TMT ainsi que l’évolution des considérations financières et de gouvernance – nécessitent une réévaluation de la meilleure façon d’y parvenir.

En particulier, le projet TMT envisage désormais de déplacer l’observatoire de Maunakea vers l’observatoire du Roque de los Muchachos, dans les îles Canaries. Ce changement, ainsi que des incertitudes plus larges liées au financement et aux échéanciers, soulève d’importantes questions stratégiques quant au rôle du Canada dans le TMT et aux voies alternatives d’accès à un VLOT.

Le comité consultatif sur le TMT de la CASCA et d’ACURA (CATAC) et le comité d’astronomie au sol de la CASCA (GAC) sollicitent donc l’avis de la communauté sur différentes options possibles, notamment :

  • Poursuivre la participation au TMT sur le nouveau site avec un investissement canadien additionnel
  • Maintenir la participation au TMT tout en recherchant un accès au European Extremely Large Telescope
  • Prioriser l’accès aux installations de l’ELT/ESO, possiblement au détriment du TMT et des installations OIR existantes

Chacune de ces options comporte des implications scientifiques, financières et stratégiques importantes, y compris des impacts potentiels sur la participation du Canada à des installations telles que l’Gemini Observatory et le Canada-France-Hawaii Telescope.

Afin d’alimenter ces discussions, nous organiserons deux assemblées publiques virtuelles, qui comprendront des panélistes :

29 avril 2026 à 12 h à 13 h (heure de l’Est)
Zoom: https://dunlap.zoom.us/j/89785304488 Passcode: 995428

14 mai 2026 à 14 h à 15 h (heure de l’Est)
Zoom: https://dunlap.zoom.us/j/89203567384 Passcode: 637073

Ces séances offriront l’occasion de passer en revue les options, de poser des questions et de faire part de vos points de vue. Afin de faciliter les échanges, nous vous encourageons à soumettre vos questions au moins 24 heures à l’avance en utilisant le lien suivant:
https://forms.gle/fP3rPpN47nkoxymY7

Nous diffusons un document de référence détaillé afin de soutenir une discussion éclairée. Un sondage sera envoyé à tous les membres de la CASCA au début du mois de mai, vous permettant de classer vos préférences parmi les options VLOT; ces résultats serviront à élaborer des recommandations pour la suite.
Compte tenu du contexte budgétaire et géopolitique actuel, il est important de souligner que toutes les options comportent des incertitudes importantes et qu’aucune issue n’est garantie. Votre contribution est donc essentielle pour orienter les priorités nationales et appuyer les discussions en cours avec les partenaires fédéraux et internationaux.

Nous encourageons fortement tous les membres de la communauté astronomique canadienne à participer à ce processus.

Cordialement,
Suresh Sivanandam (président du CATAC) et Craig Heinke (président du GAC)

CRASIES Summer School at McGill University

Please join us for the first iteration of CRASIES, the Canadian Radio Astronomy Summer Institute and Extended School, from May 25th to May 28th at McGill University. This summer school aims to give students a strong foundation in radio astronomy, preparing them to leverage, and eventually lead, Canadian radio facilities such as CHIME, CHORD, HERA, ALBATROS, and the SKA.

The school will focus on the fundamentals of radiation and radio instrumentation at >cm wavelengths, with significant time spent discussing applications of these techniques for different science interests. It is aimed at early-career researchers (MSc and PhD students) but is also open to a small number of motivated undergraduates. The school will run in-person due to its significant hands-on components but we will aim to live-stream lectures to Youtube.

CRASIES is sponsored through the RADEATE (Radio Astronomy-Driven Education and Training Excellence) program led by Adrian Liu. Attendance in the summer school (including registration and meals) will be free or charge, but any required accommodation as well as travel must be arranged by the student.

While registration for CRASIES was initially limited to students in the RADEATE program, an additional 10 to 15 spots are now open to the broader Canadian community. If you are interested, please fill out a registration application by April 14th. Priority will be given to graduate students and final year undergraduates (e.g., graduating in 2026), and then will be opened up to more undergraduates if space permits.

The registration page (as well as some more information) can be found here:

CFHT News and Updates

par Nadine Manset (Directrice des opérations scientifiques, au nom de la ʻohana TCFH)

Récemment

En octobre, le TCFH a accueilli Kara Dumaguin, la nouvelle directrice des relations communautaires. Née
et élevée à Kaʻawaloa, dans le sud de Kona, Kara a grandi dans une famille profondément enracinée
dans la pêche, l’agriculture et le service communautaire, avec un héritage culturel qui la relie à Hawaï, à
Aotearoa (Maori) et aux Philippines. La solide expérience de Kara en matière d’éducation et de gestion
communautaire renforcera le programme de sensibilisation et d'engagement communautaire du TCFH.

Toujours en octobre, la plupart des membres du personnel ont participé aux activités techniques
nécessaires pour la re-aluminure du miroir principal, une opération qui a lieu généralement tous les trois
ans. Malgré le mauvais temps qui a empêché l’accès au sommet pendant deux jours, l’;ensemble des
activités techniques intenses a été mené à bien un jour plus tôt que prévu. La qualité esthétique et
l’adhérence sont excellentes, et l'épaisseur de la couche d’aluminum répond aux attentes, dépassant les 1000 Å de manière uniforme sur toute la surface du miroir.

En décembre, les équipes Keck et TCFH ont participé à la 65e Parade de Noël de Waimea, transportant le
Père Noël dans un traîneau moderne et étincelant! Les festivités ont été suivies d’une séance
d'observation des étoiles sur la pelouse du TCFH. Ceux qui avaient besoin de se réchauffer ont été
accueillis à l'intérieur avec du chocolat chaud et des biscuits, et ont pu regarder nos observatrices
effectuer des observations à distance, en direct!

Bientôt

Le 15 octobre, le TCFH a lancé l'appel à propositions pour le Community Survey (CS). L’esprit et l’objectif principal du CS sont de refléter aussi largement que possible les intérêts scientifiques de la communauté du TCFH et de générer des données de grande valeur pour les générations futures.

Dans le cadre de cet appel, le groupe de travail (Community Survey Working Group – CSWG) a invité les équipes intéressées à soumettre des lettres d’intention (LOI) facultatives, mais fortement encouragées. Grâce aux lettres reçues, le CSWG prépare actuellement une réunion d’information qui se tiendra en janvier. Lors de cette réunion, les équipes seront encouragées à collaborer et, éventuellement, à fusionner leurs projets afin de réduire le nombre de propositions.

La date limite de soumission des propositions est le 30 avril 2026. Des informations supplémentaires sur
le CS et l’appel à propositions sont disponibles. Pour toute question ou demande d’information, veuillez contacter le CSWG par courriel à l’adresse suivante : cswg-info@cfht.hawaii.edu

SKA Update

By Alex Hill (UBC Okanagan) and the ACACS Committee

The SKA is under construction as the world’s largest telescope. It will consist of radio interferometers in Australia (a low-frequency, 50-350 MHz, array of dipoles, SKA-Low) and in South Africa (a mid-frequency, 350 MHz to 14 GHz, array of dishes, SKA-Mid). Canada  is a treaty member of the SKA Observatory (SKAO). In this update, we report on SKA-related developments, especially in Canada, from the second half of 2025.

SKA construction is moving forward at both sites, as is the development of Canadian contributions to SKA. NRC has delivered the cryogenic low-noise amplifiers and the Mid Correlator/Beamformer to the SKA-Mid site in South Africa. Canada has begun the hiring of scientific and technical staff with SKA funds; the first two Canadian SKA Scientists , Dr Alice Curtin and Dr Adam Dong, have begun (or will shortly begin) their positions at McGill University and York University respectively. Canada has established an SKA Regional Centre (CanSRC) as an outgrowth of the Canadian Astronomy Data Centre (CADC). SRCs in member countries and regions will ultimately be responsible for serving and enabling analysis of SKA data; typically PIs will access and analyze their data remotely on SRCs rather than downloading the very large SKA data sets. CanSRC is one of 9 validated SRCNet “v0.1” nodes, and CADC products such as the Canadian Advanced Network for Astronomical Research (CANFAR) and Common Archive Observation Model (CAOM) are being incorporated as fundamental (and mandatory) parts of SRCNet going forward.

SKA-Low science commissioning proceeds apace, as described in the first SKAO science community webinar on November 18 (https://www.skao.int/en/science-users/670/skao-science-community-webinars). SKA-Low per-antenna sensitivity is as anticipated over the full frequency range, and interferometric fringes, continuum images, Faraday synthesis spectra, and pulsar timing results show that the end-to-end instrument is working as expected. Initial single-station polarization measurements also match expectations. SKA-Mid construction lags about two years behind SKA-Low, but construction is proceeding and first fringes are expected soon.

Funding is not yet fully secured for the baseline design, Array Assembly 4 (AA4). Therefore SKAO has implemented a staged delivery of SKA capabilities. An intermediate stage, AA*, is thus planned instead which will deliver all planned observing modes at reduced capacity while SKAO works to secure funding for AA4. SKA-Low at AA* was planned to consist of 307 Low stations (but see discussion of deferrals below) with a maximum baseline of 74 km; SKA-Mid at AA* will consist of 144 Mid dishes with a maximum baseline of 36 km (plus one dish at 108 km). AA4 is projected to have 512 Low stations (max baseline 74 km, as in AA*) and 197 Mid dishes (max baseline 197 km).

Fig 1. Timeline for key scientific milestones

There is increasing clarity on the timeline for key scientific milestones towards the delivery of the SKA’s capabilities, which is described in some detail on the SKAO web site  and illustrated in Figure 1. The earliest Array Assembly that will be accessible to the international scientific community is AA2, from which the community will see the first science verification data from SKA-Low in 2027 and from SKA-Mid in 2029. It is expected that the international scientific community will have an opportunity to suggest science verification ideas to SKAO in the months leading towards AA2, i.e., in mid-2026 for SKA-Low. Both the visibilities and calibrated datasets will be made publicly available during science verification to allow the international community to test SKAO pipelines and assess the data quality directly. Observing modes and capabilities will be rolled out on the SKA starting with AA2, and will increase in complexity and variety as the system progresses through construction and early operations. Community members interested in the most recent updates regarding the path to science for the SKA can register their interest on the community webinars page as well as consulting documentation from past webinars. Future members who are interested in receiving updates or providing feedback about tools and capabilities can also register their interest. Community members may also join the science working groups.

In June, SKA announced a delay in timelines, primarily a two year delay in the delivery of SKA-Mid, as described in the June Cassiopeia update. In November, SKA Council approved the further deferral of some capabilities in AA* following a budget exercise which identified budgetary gaps. These deferrals were announced to the community in SKAO community webinars in November 2025, for which slides are available. SKAO’s stated intent is to restore these capabilities as soon as financially viable. 50 stations in the core of AA* Low will be deferred, reducing the number of stations from 307 to 257. The number of pulsar search beams will be reduced by ≈80%, to 50 for Low and 200 for Mid. For some science cases, this loss of sensitivity can be made up by integrating for longer. For other science cases, especially transients and pulsar search, the lost beams are a significant loss of capability. The reduced sensitivity due to the deferred capability would be particularly substantial for epoch of reionization HI science, depending on which stations are removed. The epoch of reionization SWG (co-chair: Dr Adrian Liu, McGill) is evaluating the impact.

Key Science Projects will not begin until Cycle 3, with the SKA instead operating as a PI-driven observatory in the initial cycles, including shared-risk time. SKA time allocation and data access policies are published. The ACURA-CASCA Advisory Committee on the SKA (ACACS; co-chairs Dr Alex Hill and Dr Greg Sivakoff) intends to consult the Canadian community to evaluate whether to advocate for changes such as considering both observing time and processing load, instead of only observing time as is currently planned for early observing cycles, when computing the resourcing cost of a program.

CCAT/FYST Update

CCAT Update

By/par Mike Fich (Waterloo Centre for Astrophysics, fich@uwaterloo.ca) and the Canadian CCAT team

The accompanying image shows the Fred Young Submillimeter telescope (FYST) on December 18, 2025.  Because of the difficulty of working at such high altitude FYST was assembled in large structures at the factory in Germany.  The first pieces were received in April 2025 and the last – the mirrors – arrived at the site in the second week of November.  (The large wooden box at the lower right side in the image contains the primary mirror.) Since May there has been a continuous process of lifting these pieces into place.  The hope was that this would be completed by the end of 2025 but the completion date for this phase is now expected to be Jan 31, 2026.  The team maintains a public webpage showing the progress (see “Gallery” at ccatobservatory.org).

The Fred Young Submnillimeter Telescope (FYMT) on December 18, 2025

At the same time the work on instrumentation has continued and first light instruments are expected to arrive in February 2026 and will be installed right away.  These are a high priority as they are needed for commissioning the telescope.  It is expected that “First Light” will occur on or around 1 April, 2026. A formal “Ribbon Cutting” event to celebrate the completion of FYST will be held Thursday, April 9, 2026 at our CCAT Observatory site. Two days of events are planned in advance of this in and around San Pedro de Atacama to enable participants to accustom themselves to the high altitude.

FYST is a 6-meter diameter submillimeter survey telescope and is located at the best submillimetre site that has been identified anywhere in the world.  The CCAT partnership is led by Cornell University with German, Canadian, and Chilean partners. The Canadian participation is channeled through the Canadian Atacama Telescope Consortium (CATC) and includes researchers at ten Canadian universities. FYST will only be used for continuous multi-year surveying, both all-sky and several moderate area but very deep surveys.  Also, with its rapid scan speed and very large instantaneous sky coverage FYST will map large areas many times per day providing time domain coverage never before attained at submillimeter wavelengths.

The CCAT team is very much open to new members. We are especially encouraging new science ideas that we can explore with the amazing survey datasets we will create with FYST. If you have an interest in participating in the technology development (we have begun the development of the second generation instruments!) or in any of the Key Projects please contact Norm Murray (a CCAT Director), or a Key Project leader (listed on the website above).
