2016 J. S. Plaskett Medal

CASCA is pleased to announce Dr. Jonathan Gagné as the 2016 recipient of the J.S. Plaskett Medal.

Dr. Gagné completed his doctoral studies at l’Université de Montréal under the supervision of Dr. David Lafrenière and Dr. René Doyon. His thesis, entitled “La recherche de naines brunes et étoiles de faible masse dans les associations cinématiques jeunes du voisinage solaire”, identifies and characterizes new substellar mass objects that belong to nearby young associations of stars. Dr. Gagné developed a powerful new algorithm to select highly probable substellar objects in young associations that is now widely used by the community. He also carried out an all-sky survey to identify, follow-up and characterize actual candidates, more than doubling the number of confirmed brown dwarfs.
Dr. Gagné is now widely recognized as a leading figure in the study of nearby young substellar objects.

Dr. Gagné is currently a Sagan Postdoctoral Fellow in the Department of Terrestrial Magnetism at the Carnegie Institution for Science, where he will work to identify and characterize young brown dwarfs with only a few times the mass of Jupiter.

CASCA congratulates Dr. Gagné on the receipt of the 2016 J.S. Plaskett Medal.

Dunlap Award for Innovation in Astronomical Research Tools

CASCA is pleased to announce Dr. Peter Stetson, from NRC-Herzberg, as the 2016 recipient of the Dunlap Award.

Dr. Stetson obtained his Ph.D. in Astronomy at Yale in 1979. After a short research fellowship at Yale he took a Carnegie Fellowship at the Mount Wilson and Las Campanas Observatories, subsequently moving to the Dominion Astrophysical Observatory (DAO) of NRC-Herzberg in 1983.
Dr. Stetson has been the principal research officer at DAO since 2003.
He was elected as a Fellow of the Royal Society of Canada in 2006, and was awarded the George van Biesbroeck Prize of the American Astronomical Society in 2008.

To address the problem of measuring the properties of stars in digital images from the earliest CCDs, Dr. Stetson developed and released the DAOPHOT program in 1986. He has single-handedly maintained, improved, and supported it since then. Countless investigators have used DAOPHOT; the Hubble Space Telescope Key Project to measure the size of the Universe and the Nobel Prize-winning discovery of dark energy are but two transformational scientific results that exploit its photometry. Dr. Stetson’s more recent spectral line measurement code, DAOSPEC, has been adopted by many of the world’s largest optical facilities. Additionally, Dr. Stetson’s carefully calibrated, freely available photometric standard star catalog now exceeds 114,000 objects, and underpins the majority of photometric observations carried out today. Dr. Stetson has also long served as an image structure expert for senior National Research Council engineers, impacting the design of instruments for the nex
t generation of large facilities such as the Thirty Meter Telescope.

CASCA congratulates Dr. Stetson on the receipt of the 2016 Dunlap Award.

Qilak Award

CASCA is pleased to announce Dr. Jaymie Matthews, from the University of British Columbia, as the 2016 recipient of the Qilak Award for Astronomy Communications, Public Education and Outreach.

After obtaining his Ph.D. from the University of Western Ontario in 1987, Dr. Matthews held positions at Western and l’Université de Montréal before moving to the University of British Columbia as a Killam Postdoctoral Fellow in 1988. He obtained tenure at UBC in 2000, and has been a full professor there since 2008.

Dr. Matthews’ dedication and boundless enthusiasm for communicating with the public about astronomy are illustrated by the dozens of outreach activities in which he participates annually, ranging from public presentations, to radio interviews, to campus tours, to TV show consultations. Beyond his legendary teaching reputation at UBC, he has given courses aimed at younger children as well as special lectures in Vancouver’s Downtown Eastside, the First Nations Summer Science Programme, and the Canadian Association of Physics (CAP) undergraduate lecture series, among many others. In recognition of these efforts, Dr. Matthews received the CAP Education Medal in 2002, was named an officer of the Order of Canada in 2006, and received the Queen Elizabeth II Diamond Jubilee Medal in 2012.

Please join CASCA in thanking Dr. Matthews for his selfless dedication to improving public understanding and appreciation of science and astronomy.

2016 Beals Award

CASCA is pleased to announce Dr. Chris Pritchet, from the University of Victoria, as the 2016 recipient of the Carlyle S. Beals Award.

Dr. Pritchet obtained his Ph.D. in Astronomy from the University of Toronto in 1975. After holding positions at the University of British Columbia, the Dominion Astrophysical Observatory and the University of Calgary, Dr. Pritchet has been on faculty in the Department of Physics and Astronomy at the University of Victoria since 1982. He was Department Chair from 1995-1998, and the chair of the 2010-2020 Long Range Plan Committee for Canadian Astronomy. Dr. Pritchet is currently an associate fellow of the CIfAR Cosmology and Gravity program as well as the principal investigator of CANFAR, which coordinates astronomical computing resources across Canada.

Dr. Pritchet’s research in observational cosmology combines the best available technology with sophisticated analysis techniques. His discovery, along with Sidney van den Bergh, of RR Lyrae variable stars in the Andromeda galaxy is recognized as a vital contribution to fixing distance scales in the Local Group. He is a leader of the Supernova Legacy Survey that has provided precise measurements of dark matter and dark energy in the Universe, and he initiated the close galaxy pair study in the Canadian Network for Observational Cosmology redshift survey. He has also produced important results on galaxy mass profiles, globular cluster distributions, and stellar populations of galaxies in the local universe. Dr. Pritchet has mentored over three dozen graduate students and postdoctoral fellows, and has also made important contributions to astronomy education and outreach as a Galileo lecturer of the International Year of Astronomy and the initiator and primary organizer of Vict
oria’s Café Scientifique.

CASCA congratulates Dr. Pritchet on a distinguished career of scientific achievement and community service.
