Prix Carlyle S. Beals 2026: Prof. Arif Babul

Arif Babul

La CASCA a le plaisir d’annoncer que le professeur Arif Babul est le lauréat du Prix Carlyle S. Beals 2026 en reconnaissance de ses réalisations exceptionnelles dans le domaine de la recherche.

Le professeur Babul est une figure de proue de renommée mondiale dans le domaine de la cosmologie physique, reconnu pour ses travaux sur la formation, l’évolution et la physique des groupes et des amas de galaxies. Il a débuté sa carrière au Canada, où il a obtenu un baccalauréat avec mention en sciences de l’ingénierie à l’Université de Toronto en 1985, et il occupe actuellement le poste de professeur émérite à l’Université de Victoria. Tout au long de sa carrière, le professeur Babul a contribué à plusieurs découvertes révolutionnaires qui ont redéfini le domaine de la cosmologie. Il a notamment été l’un des premiers à reconnaître que le rayonnement des premières étoiles et des quasars pouvait influencer de manière significative l’évolution des structures cosmiques; il a été à l’avant-garde du traitement réaliste de la dynamique des trous noirs dans les simulations cosmologiques, et il a mené des recherches sur les sources d’ondes gravitationnelles à l’échelle des nanohertz qui ont des implications importantes pour les installations astronomiques actuelles (réseaux de chronométrage des pulsars) et futures (Square Kilometre Array) auxquelles le Canada participe. Au-delà de son incroyable parcours de pionnier en recherche, le professeur Babul a formé de nombreux nouveaux chercheurs, dont beaucoup occupent désormais des postes de haut niveau dans le milieu universitaire et dans l’industrie. Il a aussi été à l’origine de progrès significatifs dans la promotion de la diversité et de l’inclusion dans le domaine de l’astronomie, et il demeure un fier ambassadeur de l’astronomie canadienne sur la scène internationale. Le professeur Babul incarne les plus hauts standards d’excellence scientifique et de leadership au sein de la communauté astronomique canadienne.

la médaille J. S. Plaskett 2026: Dr. Alan Knee

Dr Alan Knee

La CASCA a le plaisir d’annoncer que le Dr Alan Knee est le lauréat de la médaille J. S. Plaskett 2026 pour la thèse de doctorat la plus remarquable en astronomie ou en astrophysique.

Le Dr Knee a obtenu son doctorat en 2025 sous la direction du Dr Jess McIver à l’Université de la Colombie-Britannique, et il occupe aujourd’hui un poste de chercheur postdoctoral à l’Université du Michigan. Sa thèse de doctorat, intitulée « Recherche de nouvelles sources d’ondes gravitationnelles à l’aide de détecteurs terrestres et spatiaux », explore des sources d’ondes gravitationnelles encore inconnues à diverses échelles, de notre propre galaxie jusqu’aux confins de l’Univers. Les travaux du Dr Knee apportent un éclairage inédit sur la matière ultra-dense des étoiles à neutrons, la dynamique du centre galactique et l’origine des sources lointaines détectées par les observatoires LIGO et Virgo. Les réalisations du Dr Knee ont nécessité une grande maîtrise des instruments de détection terrestres et spatiaux, ainsi que le développement d’approches statistiques de pointe. En repoussant ainsi les limites de détection des sources d’ondes gravitationnelles, des divers types de détecteurs et de méthodologies très variés, la thèse de doctorat du Dr Knee se distingue par l’étendue exceptionnelle de ses travaux à fort impact.

La CASCA est ravie de récompenser les réalisations du Dr Knee par ce prix.

Prix Qilak 2026: Drs Lawler and Boley

Drs Lawler and Boley

La CASCA a le plaisir d’annoncer que la professeure Samantha Lawler et le professeur Aaron Boley sont les lauréats du prix Qilak 2026, qui récompense des activités récentes et marquantes de communication, d’éducation et de sensibilisation du public à l’astronomie.

Comme le savent tous les astronomes et amateurs d’astronomie canadiens, le ciel nocturne est menacé par la pollution lumineuse et la pollution du spectre électromagnétique, ainsi que par la surpopulation des orbites terrestres par les satellites. Face à ces pressions, il est devenu crucial de sensibiliser tant le grand public que les législateurs à ces menaces qui pèsent sur la pratique de l’astronomie. C’est cette tâche importante que les professeurs Lawler et Boley se sont engagés à accomplir. Sur les questions liées à la pollution lumineuse, à la prolifération des satellites et à leurs effets sur le ciel nocturne, le spectre radioélectrique et les environnements orbitaux, ils ont rencontré des représentants du gouvernement et des décideurs, et ils ont sans relâche adressé des pétitions à divers organismes, dont l’Agence spatiale canadienne, Innovation, Sciences et Développement économique Canada, Transports Canada, le ministère de la Défense nationale et Affaires mondiales Canada, ainsi qu’à la Commission fédérale des communications des États-Unis, l’Agence spatiale britannique et l’Autorité de l’aviation civile britannique. Ils ont également fait de nombreuses apparitions dans les médias pour traiter de ces sujets, produit du matériel pédagogique pour les écoles et présenté des dizaines de conférences publiques afin de sensibiliser le public à ces questions importantes.

La CASCA est ravie de rendre hommage à la professeure Samantha Lawler et au professeur Aaron Boley pour leurs contributions exceptionnelles à la préservation du ciel nocturne.

2026 Prix Dunlap: professeur Michel (Mike) Fich

Michel Fich

La CASCA a le plaisir d’annoncer que le professeur Michel (Mike) Fich est le lauréat du Prix Dunlap 2026 pour l’innovation dans les outils de recherche astronomique.

Ce prix récompense le leadership constant et visionnaire du professeur Fich dans le développement et la participation canadienne à la mise au point d’instruments astronomiques révolutionnaires dans les domaines de l’infrarouge et des ondes millimétriques. Tout au long de sa carrière, le professeur Fich a été l’un des principaux moteurs de nombreuses initiatives en matière d’instrumentation, notamment Herschel/HIFI, JCMT/SCUBA-2 et, plus récemment, le télescope submillimétrique Fred Young de l’observatoire CCAT-prime. L’importante participation du Canada à ces initiatives internationales majeures est due en grande partie au leadership du professeur Fich au nom de la communauté astronomique canadienne. Dans certains cas, sans sa contribution, ces instruments n’auraient probablement jamais vu le jour. Tout au long de sa carrière, il a obtenu des dizaines de millions de dollars de financement pour des infrastructures de recherche, dirigé des équipes de chercheurs et permis à des générations de scientifiques d’explorer l’univers aux longueurs d’onde infrarouge, sous-millimétriques et millimétriques à l’aide d’instruments qui ont collectivement été cités des dizaines de milliers de fois dans la littérature scientifique. Plus récemment, en tant que chercheur principal canadien et membre du conseil d’administration de FYST/CCAT-prime, le professeur Fich a guidé le projet depuis sa conception jusqu’à sa réalisation, notamment en définissant ses objectifs scientifiques, en obtenant plus de dix millions de dollars de financement et en assurant le leadership du Canada dans le développement d’instruments clés. Son implication directe dans la conception, le développement de logiciels et la gestion du projet a été essentielle au succès du télescope. Inauguré le 9 avril 2026, le FYST est maintenant en position d’offrir de l’imagerie et de la spectroscopie d’une sensibilité sans précédent, plaçant ainsi le Canada à l’avant-garde de la recherche sous-millimétrique à grand champ.

La CASCA est ravie de reconnaître les efforts du professeur Fich par ce prix.

President’s Message

Dear CASCA Community,

I am closing out the final months of my term as CASCA president in a time of significant upheaval.  In light of recent and dramatic political changes, the expectations of long-standing partnerships are shifting.  We will have significant turnover in the CASCA Board in June, and the current members aim to finish specific community recommendations from the 2020 Long Range Plan before the transition.  Adopting a Mission and Values statement is foundational to this end, and the final consultation on the wording is open now.  Subsequently, we will have another round of consultation on a proposed Code of Conduct.  These documents are important for defining who we are and aspire to be, and how we treat each other.

The Mid-Term Review Committee has been working hard to gather information and engage our community.  The participation in the Town Halls to date has been robust and productive.  We will have further opportunity for discussion (in-person and virtual) at the CASCA AGM in Halifax in June.  Thank you to the Committee and all of you who have contributed to date in the consultations.  We are cognizant that the landscape in March 2025 is remarkably different than when papers and reports were submitted at the end of 2024.  We are in the process of figuring out how to incorporate new realities without being too reactive.  I ask for your patience as we work to navigate this challenge.

CASCA is only as effective as its leadership and the contributions of its members.  Suggestions of potential candidates (including yourself!) for the open Board positions (VP, Treasurer, Secretary, and Directors) continue to be most welcome.

Best wishes,
Sarah Gallagher

President’s Message

By Sarah Gallagher (Western)

Dear CASCA Community,

It has been an honour to continue to collaborate with the CASCA Board, committees, members, and partners since the 2024 Annual General Meeting to advance the priorities of our community. Below are some of the activities that we have been undertaking over the past six months.

The Coalition for Canadian Astronomy continues to support the CASTOR mission  our top priority for space astronomy. To start, we submitted a pre-budget brief to Parliament. At the end of November, the Coalition met with the leadership of the National Research Council and the Canadian Space Agency to hear from them and update them on the mission. The CASTOR team and industrial partners have come together to ask for funding for a Phase A study to continue progress and complete detailed costing for the full mission. This step is considered essential to maintain the confidence of our international partners in what would be the first Canadian-led major space astronomy mission.

To maintain ties and communication with our partners, I continue to meet regularly with Gilles Joncas, the Executive Director of ACURA, and the leadership of CAP. I represented our community in the CAP Strategic Planning process, and we endorsed their submission to the Tri-Councils on the consultation for the capstone agency that will oversee mission-driven and interdisciplinary research funded by the granting councils. Of particular concern for us is robust and sustained support for major facilities, which is directly relevant to our domestic observatories.

The Mid-Term Review was launched in August 2024 and is well underway. The panel has solicited community papers and committee reports to set up further consultations for the beginning of 2025. I have heard multiple times from our partners in government as well as other science communities about the value of our community engagement and consensus-building process through long-range planning and interim mid-term reviews. This process requires substantial and repeated effort, but speaking with a coherent vision is extremely powerful for advancing our ambitious goals. Thank you to the panel and all of you who are contributing.

The last quarter of my term as President starts this January. We will have significant turnover in the Board for the next term, with two Directors, the Treasurer, the Secretary, and the Vice President cycling off. Please consider agreeing or volunteering to stand for election. I’ve been truly fortunate to have such fantastic colleagues during my tenure so far, and I know that given the depth of talent in our community that the new members who step up to take over will be just as committed. I wish all CASCA members a restorative holiday break and a happy 2025!

Best wishes, Sarah Gallagher

President’s Message

(Cassiopeia – hiver 2023)

Dear CASCA Community,

It has been my great pleasure to work with the CASCA Board and CASCA committees and members since the 2023 AGM to connect our society and advance our priorities as articulated in the 2020 Long Range Plan (LRP). Below, I’ll highlight some key activities to that end.

The Coalition for Canadian Astronomy has been active this fall lobbying the federal government in support of the CASTOR mission (castormission.org), our top priority for space astronomy. We have had in-person or virtual meetings with ISED, Finance, the Office of the Chief Science Advisor, and Prime Minister’s Office. In general, the reception was encouraging, but this is a tough budget year. The CASTOR team has put together an impressive portfolio of letters of support from 13 university Vice Presidents of Research, 3 Canadian aerospace companies, and 2 international space agencies that we have submitted as follow up to the meetings. Space.com featured the CASTOR mission in a glowing profile. The 2024 budget is expected in March/April timeframe, and we’ll continue our efforts in the new year.

In an effort to increase coordination and communication with ACURA, Gilles Joncas (Executive Director) and I have been meeting monthly. I have also been meeting monthly with Bill Whelan, President of the Canadian Association of Physicists (CAP), to coordinate efforts with our sister society. We are exploring potential ways to partner as well as sharing information about what we are doing on several fronts, including lobbying, outreach, and communications. CAP sent a letter of support for CASTOR that was included with our portfolio. We have endorsed their pre-budget submission as well.

A priority for the coming year is to develop drafts of an updated CASCA mission statement, and new code of conduct and ethics and values statements in time for a vote at the AGM in June 2024. These drafts will be developed in coordination between the Board, the Equity and Inclusivity Committee, and the LRP Community Recommendations Implementation Committee, and circulated well in advance of a vote to get feedback from the community. We consider these documents to be necessary to help us prioritize CASCA activities given our limited human and financial resources.

CASCA has endorsed NSERC’s Dimensions Charter to indicate our commitment to equity, diversity and inclusion (LRP Recommendation 37).

My initial commitment to CASCA was to serve for one year, but I have decided to extend this commitment to the full two year term. Working on behalf of the society with our excellent team has been rewarding so far, and I would like another year to advance more of the important work that we have underway.

I wish all CASCA members a restorative holiday break and a happy 2024!

Best wishes, Sarah

President’s Message

par Chris Wilson (CASCA President)
(Cassiopeia – printemps 2023)

First, some good news: the Federal government has announced its intent to seek full membership for Canada in the Square Kilometre Array Observatory! Congratulations to everyone who has worked to make this a reality. More details can be found in the SKA update in this newsletter.

The CASCA Board has held two regular monthly meetings since my last report. In this report I will focus on 2 major initiatives that are in progress: a review of our ground-based optical/infrared facilities (10m-class and smaller), and a plan for a part-time Westar Lectureship co-ordinator.

In their December 2022 report to the CASCA Board, the Ground-based Astronomy Committee (GAC) recommended that we undertake a thorough review of existing and potential optical/infrared (O/IR) facilities that are or could be accessible to Canadian astronomers. The CASCA Board agreed that the need for this review is sufficiently urgent to scheduling it ahead of the Mid-Term Review (MTR) of the 2020 Long Range Plan that would be carried out in 2025. The O/IR review committee will be tasked with assessing science, technical readiness, schedule, and balance between community desires. I’m very pleased to announce that Doug Welch from McMaster University has agreed to chair this review committee.

In my December 2022 article, I mentioned that the Board had met with several members of the Westar subcommittee. At that meeting, we had discussed the possibility of hiring a co-ordinator to support the revision and expansion of the Westar Lectureship program, and possibly other Education and Public Outreach initiatives as well. Both an expansion of the Westar Lectureship program and an EPO coordinator paid by CASCA were recommendations of the 2020 Long Range Plan. The Westar subcommittee submitted a concrete proposal that the Board considered at our March meeting. This proposal included two options: a part-time Westar-only coordinator position, or a full-time National Outreach Coordinator, with Westar coordination being part of that role. The Board found that a full-time position is not within the scope of CASCA’s current budget without a large increase in dues or via a cost-sharing program with one or more individual universities. Therefore, the Board approved a motion to support a Westar co-ordinator at a part time level for up to 3 years. Final details of the funding available for this position will be reviewed and approved at the next Board meeting.

In other news, all current Board members have now taken some initial Indigenous awareness training by completing the course “4 Seasons of Reconciliation” offered by Reconciliation Education. We submitted our annual performance questionnaire related to IAU activities of the community to NRC in February; thanks to Rob Thacker who took this task off my hands. The CASCA Board also reviewed all applications for new IAU membership and these applications have now been passed on to the relevant IAU review committee. The Board approved an increase in the hourly rate of pay for the CASCA webmaster, who has not had a pay increase in several years. We have also been following up with CASCA members who were in arrears on their dues; thank you to everyone who has renewed recently.

The next CASCA AGM will be held June 13-15, 2023, in Penticton, B.C. This will be our first in-person meeting in 4 years, so I encourage you to attend and bring your students! The CASCA Board is looking for an institution to host the 2024 AGM; if your department is interested in volunteering, please contact CASCA Vice-President Adam Muzzin.

As a reminder, there will be 3 open positions on the CASCA Board for election at the 2023 June AGM: 2 for Director and 1 for President. Please consider standing for election yourself or encouraging other good candidates to stand. Suggestions can be sent to Rob Thacker, who chairs the Nominating Committee, or via the nomination form to the CASCA secretary, Rob Cockcroft.

Finally, I would like to acknowledge that progress continues to be slow on various aspects of Board business. A lot of the CASCA day-to-day work and planning falls on the President, who not only chairs the Board but is also the Chief Executive Officer of the Corporation. Unfortunately, I have not been able to devote as much time to CASCA work as I had planned: I caught COVID in early November and have been suffering from first COVID and now long COVID symptoms for the past 4 months. I appreciate your patience if responses to emails are slow or if some aspects of CASCA business take longer to make progress. Special thanks to other members of the Board who are taking on tasks that I would normally be doing, especially Julie Hlavaceck-Larrondo who has been chairing the Board meetings and leading the organization of the optical/infrared review committee.

Wishing you all a good end of semester and looking forward to seeing many of you in Penticton in June,

Chris

President’s Message

(Cassiopeia – été 2022)

I would like to start this President’s report by welcoming the new members of the CASCA Board: Adam Muzzin as Vice President, Rob Cockcroft as Secretary, and Renee Hlozek and Karun Thanjavur as new Directors. Lewis Knee has been acclaimed to a second term as CASCA Treasurer, while Laura Parker and Julie Hlavacek-Larrondo are continuing in their third year as Directors. Thanks to all of you for being willing to serve! Thank you also to the outgoing Board members: Judith Irwin (Secretary), Ivana Damjanov (Director), and Etienne Artigau (Director). A special thank you to Erik Rosolowsky (Acting Vice-President) and Rob Thacker (Acting President) for stepping up to serve in these important CASCA roles last summer.

As those of you who attended the CASCA Business Meeting in May will know, I have agreed to step in to serve as CASCA Acting President for 2022-2023. Like Rob Thacker this past year, I am in this position under Bylaw 9.1, and will not be continuing in this position beyond the 2023 AGM. Thus, in 2023 we will look to elect a new President, as well as two new Directors. More information about the elections, including how to nominate someone or be nominated yourself, will be circulated later this year.

As I have been in the Acting President position for just over a month, this message will provide a short update on a few key areas. I plan to provide a more extensive discussion in my fall message, once I have had more time to review what the CASCA Board has on its “to do” list.

Coalition activities continue to focus on the Square Kilometre Array (SKA), where things appear to be progressing well. The SKA is now one year into construction of SKA Phase 1 and continues to evolve rapidly. Canada’s scientists and engineers are participating in SKA through March 2023 via a co-operation agreement between NRC and the SKAO. To continue our leading role in SKA construction deliverables such as the SKA1-mid correlator will require the Canadian government to commit to construction and operations funding quite soon. Please refer to the excellent article by Kristine Spekkens for more information on the SKA.

Another important initiative that is gaining significant momentum is CASTOR, a Canadian-led optical-UV space telescope and the highest priority in space astronomy in the 2020 Long Range Plan (LRP2020). The Canadian Space Agency (CSA) held a virtual Canadian Space Exploration Workshop June 14-16, 2022, which I am sure many of you attended. The workshop provided an opportunity to discuss ideas for Canadian space exploration over the next 30 years and will serve as input to CSA’s planning process.

The LRP Community Recommendations Implementation Committee (LCRIC) has continued their hard work over the past three months. They hosted a well-attended webinar on “Including Indigenous voices in astronomy education” at the end of March. They have drafted a very important policy paper on land and consent (LRP2020 Recommendation #1) as it relates to new astronomical facilities that has been circulated to the community and was presented and discussed in a special session at the CASCA AGM. Sharon Morsink has taken over as chair of LCRIC for 2022-23 and I look forward to working closely with her and the rest of the LCRIC as they work to move the societal recommendations from LRP2020 forward.

I hope everyone has a healthy and productive summer,

Chris
