Transfer complete!

So I’ve run all of the tests I can think of and this morning’s transfer of the site to a new machine seems to have finished with only one small side-effect: some e-mail clients for the domain addresses seem to think that the last week of e-mail reading didn’t happen and so you’ll have to, alas, reread some mail if this happens to you. Other than that everything seems to be just as it was before the move.

If you have any questions or concerns about the move feel free to contact me at webmaster at

Scheduled site maintenance morning of November 9th

Your friendly neighbourhood webmaster here.

Our ISP informs me that, at some random moment during the morning (EDT) of Wednesday, November 9th all of our stuff will be moved to a shiny new machine. This means some downtime as the new machine is at a new address (IP Address that is):

Schedule (all times EDT):

  • Around 5 pm on the 8th I will make a full backup of the site and back that up (encrypted) on one of my own systems separate from those of the ISP. Probably nothing will be lost in the transfer to the new machine but if it is everything up to that point can certainly be restored
  • Late on the night of the 8th I will set the site’s address to the new coördinates. This means that until the move is complete (perhaps just after midnight; perhaps around noon) attempts to reach the site or any of its facilities will fail.
  • When the transfer is complete the site should be reachable and everything as it was before the move. A post to that effect will be posted on the site, tagged CASCA In the news, so that you can tell that you’re seeing the newest version of the site and not some cached version of the old one.
  • If something does go wrong a mass mailing to the general membership will be made outlining the situation. Our mass mailing system is on a completely different system than the website and should not be affected by the move.

Other changes

  • If you have FTP access to the site note that the new address of the FTP servers will be
  • People who’ve been on the system for a long time may have the address set as the address of the e-mail server they use with their e-mail address. This may not continue to work. The better address to use is
  • If you wish to contact me to help with e-mail problems encountered after the move it is possible that I’m having the same problems so my regular address of webmaster at may not work! CC such requests to witheringsnodgrass at

Professeur Christine Wilson remporte le Prix Exécutif 2022

Tous les deux ans, le conseil d’administration de la CASCA a l’honneur de décerner le prix exécutif pour service exceptionnel « à une personne qui a contribué de façon soutenue à renforcer la communauté astronomique canadienne et à accroître son impact au niveau régional, national et/ou international ». La professeure Christine Wilson, de l’Université McMaster, est la récipiendaire du prix exécutif 2022.

L’engagement exceptionnel de Dre Wilson envers la communauté astronomique canadienne a été évident dès le début de sa carrière. Après son retour au Canada pour occuper un poste de professeure à l’Université McMaster en 1992, elle a immédiatement contribué à plusieurs comités clés, y compris un comité du CNRC sur une nouvelle installation radio nationale, et a été nommée à un poste de directrice de la CASCA en 1996. Au cours des décennies suivantes, elle a siégé à de nombreux comités de la CASCA, dont un comité d’examen à mi-parcours, occupant souvent des postes simultanément, ainsi que la vice-présidence en 2012-2014 et la présidence en 2014-2016. Plus récemment, le professeure Wilson a présidé le comité de mise en œuvre des recommandations communautaires du plan à long terme de la CASCA (LCRIC).

Dans le domaine de l’astronomie submm, sa réputation d’excellence en recherche ainsi que ses compétences en gestion largement reconnues l’ont amenée à assumer des rôles de leadership clés pour les intérêts scientifiques et logiciels canadiens dans le projet ALMA. Elle a été scientifique canadienne du projet ALMA de 1999 à 2011, présidente du comité directeur scientifique canadien de l’ALMA de 2001 à 2010, ainsi que membre de quatre autres comités et conseils clés de l’ALMA. S’il ne fait aucun doute que ALMA est le fruit d’un important travail d’équipe, ses efforts ont été essentiels pour faire de ALMA le grand succès qu’il est, tant du point de vue de la collaboration canadienne qu’internationale.

Pendant trois décennies, le Dre Christine Wilson a été un modèle et une ambassadrice engagée de l’astronomie au Canada. En lui décernant ce prix au nom de la communauté astronomique canadienne, le conseil d’administration de la CASCA reconnaît sa contribution essentielle à la communauté professionnelle canadienne et internationale, et lui adresse ses plus sincères remerciements.

The National Research Council of Canada’s Herzberg Astronomy and Astrophysics Research Centre (NRC-HAA), is seeking a scientist or engineer with strong interests in the development of next generation Adaptive Optics (AO) systems to support the development of optical instrumentation at the Herzberg Astronomy and Astrophysics Research Centre (HAA). HAA has a rare combination of staff involved in astronomy research, instrumentation design and development, engineering, data science and observatory support. The chosen candidate will be someone who shares our core values of Integrity, Excellence, Respect and Creativity.

HAA is a leading developer of instrumentation for Canada’s current and future ground- and space-based telescopes from optical through to radio wavelengths (e.g., CFHT, Gemini, TMT, ALMA, SKA). Its multi-disciplinary team includes project managers, optical, electrical, mechanical and systems engineers and technicians, signal processing experts and astronomers. Current major activities include participation in the development of optical/NIR spectrographs for Gemini including GHOST and GIRMOS, adaptive optics systems for multiple instruments on Gemini, the TMT and ELT, as well as multiple projects at radio wavelengths including correlator upgrades and central signal processing architectures for the SKA and ALMA. Alongside these facility projects, HAA maintains an active portfolio of small scale R&D activities, including the development of test benches and on-sky demonstrators on local telescopes, that provide a means for showcasing new technologies and methodologies aimed at advancing astronomical research.

The AO Developer will be someone who provides scientific and/or technical support and leadership to AO projects. They will be a member of the AO Team and will report to the AO Team Leader. The AO Team, which is part of the HAA Astronomy Technology Directorate (ATD), provides direct support to various on-going instrumentation projects and is also engaged in an ambitious R&D program that aims at developing cutting-edge technologies and methods for the next generation of AO systems that will support the long-range plans of the Canadian astronomical community.

Major facility AO instrument projects currently supported by the AO Team include TMT Narrow Field near-InfraRed AO System (NFIRAOS), The Gemini InfraRed Multi-Object Spectrograph (GIRMOS), the Gemini Planet Imager (GPI) 2.0, and the GPI Calibration Unit (CAL) 2.0. The AO Team also supports the ATD Software Team in their effort to design and develop the Herzberg Extensible Adaptive optics Real-time Toolkit (HEART), a real-time control (RTC) software toolbox that can be easily adapted to control any AO instruments. HEART is slated to be deployed on the AO instruments mentioned above. It is also expected to equip the European Large Telescope (ELT) HIgh REsolution Spectrograph (HIRES) and the ELT Multi-conjugate Adaptive Optics RelaY (MAORY).

Our AO R&D program aims at achieving technological breakthrough that will enable Canadian astronomers’ vision for new AO-assisted observational programs and that will significantly increase the scientific productivity of ground-based observatories. Our current AO R&D program focuses on key AO elements, including wavefront sensors (WFSs), deformable mirrors (DMs) and control. Current activities include technological developments such as advanced high-speed, low-noise NIR detectors and low-voltage deformable mirrors; developing novel WFSs such as non-linear wavefront sensors and novel algorithms, such as machine-learning based AO control. The technological readiness level of these developments are systematically increased by demonstrating them in the lab and on sky whenever possible. Our R&D program is supported by state-of-the-art modeling tools, two laboratories, one dedicated to general AO (AO Lab) and one dedicated to high-contrast imaging (New Earth Lab), and a local 1.2 m telescope with a Coudé room able to host on-sky experiments. The AO Team maintains extensive collaborations with partners from the international AO communities.

The AO Developer plays a leadership role in these cutting-edge science & technology projects. They work with enthusiastic, highly-invested colleagues from within the NRC and around the globe, all while representing Canada in high-profile international projects to build the biggest and most advanced scientific instruments in the world.

The AO Developer provides AO expertise at many levels, from inventing new concepts and leading their validations through R&D projects to commissioning multi-million dollar AO instruments at leading international observatories. Regular activities include improving AO modeling and simulation tools, providing technical guidance and critical analysis for designing new AO systems, providing leadership to AO projects, as well as supporting the fabrication, integration, testing and commissioning of AO instruments. The AO Developer usually works as part of highly multi-disciplinary teams that often comprises many skill levels, from under-graduate university students to senior engineers and scientists.

CASCA is pleased to announce that Dr. JJ Kavelaars is the winner of the 2022 Dunlap Award.  This award recognizes his leadership at the Canadian Astronomy Data Centre.  Over the past five years in which Dr. Kavelaars has been head of the CADC, it has provided public access to its largest number of telescope archival datasets, expanded a key initiative to bring high-performance distributed cloud computing services to Canadian astronomers via the Canadian Advanced Network for Astronomical Research (CANFAR), and laid the groundwork for new archives and processing environments for the upcoming JWST, Vera C. Rubin Observatory, and the Square Kilometre Array.  He received his PhD from Queen’s University, followed by a postdoctoral fellowship at McMaster University.  He is now a Senior Research Officer at NRC-Herzberg in Victoria as well as an adjunct professor at UVic, where in addition to leading the CADC, he continues to make groundbreaking discoveries in the Kuiper Belt using ground and space-based telescopes as well as being a part of the New Horizons Mission team.

Dr. Anthony Moffat: 2022 Carlyle S. Beals Award for Outstanding Research

CASCA is pleased to announce that Dr. Anthony Moffat is the winner of the 2022 Beals Award.  This is in recognition of decades of cutting-edge research on topics relating to massive stars, including Wolf-Rayet stars, stellar pulsations, rotation, magnetic fields, clumping, binaries, clusters, and surveys.  Many of us have used a Moffat profile: that was his work! He received his doctorates in astronomy from Ruhr-Universitaet Bochum in Germany, and has been a professor at Université de Montréal ever since, and hasn’t slowed his research output since taking emeritus status.  He has trained generations of scientists who are still working in Canada and internationally. He remains very active in research on massive stars and astronomy projects like the BRITE constellation.

Dr Deborah Good: 2022 Médaille J. S. Plaskett pour la thèse de doctorat la plus remarquable

La CASCA a le plaisir d’annoncer que Dr Deborah Good est la lauréate de la médaille J.S. Plaskett 2022, qui récompense la thèse de doctorat la plus remarquable en astronomie ou en astrophysique. Dr Good a obtenu son doctorat en 2021 sous la direction de Dr Ingrid Stairs à l’Université de la Colombie-Britannique et elle est maintenant boursière postdoctorale à l’Université du Connecticut et au Flatiron Center for Computational Astrophysics. Sa thèse, « Timing Pulsars and Detecting Radio Transients with CHIME », comprend un travail novateur sur les premiers mois de détection de pulsars et de sursauts radio rapides avec CHIME. Pour mener à bien cette recherche, elle a mené des efforts au sein de l’équipe CHIME pour calibrer les instruments, développer des logiciels d’analyse, vérifier les détections, et elle est à la fine pointe de la recherche pour tenter de découvrir si oui ou non tous les sursauts radio rapides sont des événements récurrents. Elle a également recueilli des données sur les pulsars, découvert de nombreux nouveaux pulsars et adapté l’algorithme de réductions de données NANOGrav pour qu’il fonctionne avec les données CHIME, posant ainsi les bases du traitement des données qui sera nécessaire dans les prochaines années.

Il est actuellement instructeur principal de laboratoire à l’Université de Victoria.

Call for abstracts — Interdisciplinary Origin of Life Meeting for Early Career Researchers

Dear Colleagues –

The Origin of Life Early Career Network (OoLEN) is pleased to announce that this year’s Interdisciplinary Origin of Life Meeting for Early Career Researchers (IOoL2022) will take place on August 3-5 at the University of Montreal, Canada. All expenses except travel (with possible exceptions) will be covered!

OoLEN brings together early-career scientists from multiple research areas to strengthen and accelerate the scientific output in origin of life research. Since its inception in 2018, OoLEN has grown into a global network of over a hundred members with a six-fold mission: Inclusion, Post-disciplinarity, Exchange, Communication, Community and Quality.

OoLEN’s biannual meeting, the IOoL conference, is a prime opportunity for early-career researchers to present their work on origin of life in a relaxed setting, to exchange ideas across different disciplines relevant to understanding the origin and nature of living systems, and to stimulate discussions and ideas to help guide the future of research on these topics. The IOoL meeting further provides an opportunity for early career researchers to connect with each other and immerse themselves in the community outside their own labs. A previous meeting has resulted in OoLEN’s first community paper.

Researchers interested in submitting an abstract are welcome to join the network through (please mention your intention to participate in IOoL2022 when joining the network) and then send an email to with subject line “Abstract for IOoL2022” containing a single .pdf file with the following information: name, affiliation, title, abstract (max. 250 words, in english), while also specifying if travel support is needed. Submissions will be considered both for oral presentations and poster sessions. The abstract deadline is April 22nd.

Update on CASTOR

By / par Patrick Côté, John Hutchings (NRC Herzberg Astronomy & Astrophysics Research Centre)
(Cassiopeia – Spring / printemps 2022)

The CASTOR project continues to move forward as the Long Range Plan’s highest priority in space astronomy for the 2020s.

  1. The ongoing CSA technical (STDP) study contract continues to make good progress. A recent review detailed the design and performance of the Fast Steering Mirror that will perform the fine guiding for the observatory. The recently launched James Webb Space Telescope utilizes the same guiding system, so there is significant heritage in this capability. Other work on the detectors and payload opto-mechanical issues continues.
  2. The long-awaited Phase 0 study contract is underway as of March 8. This study overlaps the STDP work, and both studies will wrap up about one year from now. The prime deliverable from the Phase 0 study will be a fully characterized and thoroughly planned mission concept, with agreed partnerships, that can move immediately into the flight Phases A to E. It is hoped that partnership details and agreements with ISRO, JPL, and UK will be formulated during this time. The Phase 0 study consists of an industrial contract (led by Honeywell Aerospace) and a science team contract (led out of NRC/HAA), and now is formally a joint project between CSA and NRC. Science working groups (SWGs) and work contracts are in place with several Canadian universities.
  3. The CASTOR and Indian INSIST teams continue to work on a common design and hold regular meetings. The partner teams also include JPL and UK, whose participation in the STDP and Phase 0 work are being formalized.
  4. The ACURA board and the Coalition are fully informed and are carrying the message from Universities to the government to prepare for flight approval and funding. We welcome colleagues to join in SWG and outreach activities.
