The 2017 R. M. Petrie Prize is awarded to Dr. Charles Beichman for his incredible career contributions to the study of extrasolar planetary systems.
Dr. Beichman is currently the Executive Director of the NASA Exoplanet Science Institute at Caltech, which is the focus of exoplanet research at NASA. Dr. Beichman’s search for evidence of planetary systems is long-standing, dating back to the first detections of planetary systems with IRAS through the Spitzer Space Telescope and now looking forward to the James Webb Space Telescope. He has published many key papers on Kuiper Belt and Asteroid Belt analogs around other stars and has developed analysis tools that were essential to several breakthrough observational results.
For the past 10 years Dr. Beichman has been closely associated with and helped to formulate NASA’s program to search for planets around other stars, serving as Chair of the Science Working Group for the Terrestrial Planet Finder (TPF) and authoring numerous articles and reports on TPF and the search for terrestrial and ultimately habitable planets. He is also involved in extensive outreach efforts that include appearances on several programs about space.
It is an honour to add Dr. Beichman’s name to the long list of distinguished past Petrie Prize recipients.

CASCA is pleased to announce Dr. Fereshteh Rajabi as the 2017 recipient of the J. S. Plaskett Medal.
Dr. Rajabi completed her doctoral studies at the University of Western Ontario under the supervision of Dr. Martin Houde. Her thesis entitled “Dicke’s Superradiance in Astrophysics” extends the mathematical description of this intriguing physical process to many phenomena of astrophysical interest. Superradiance is a quantum mechanical and coherent behaviour between closely spaced atoms or molecules (i.e., several within a wavelength) that makes them, when certain conditions are met, emit radiation that is much more focused and intense than expected. Dr. Rajabi used superradiance to elegantly explain anomalous fluxes in the 21cm line of hydrogen atom and unexplained maser flares and bursts in the envelopes of evolved stars. She made fundamental physical advances that brought superradiance out of the lab and into an ever more surprising Universe. Her work has attracted worldwide attention not only in astrophysics, but also in the field of quantum optics.
CASCA congratulates Dr. Rajabi on the receipt of the 2016 Plaskett medal for her highly original work to advance our understanding of fascinating transient phenomena in the Universe.
CASCA is pleased to announce that the recipient of the inaugural Harvey B. Richer Gold Medal is Dr. David Lafrenière of the Université de Montréal.
Dr. Lafrenière earned his PhD in 2007 from the Université de Montréal and went on to the University of Toronto as a postdoctoral fellow. He returned to Montréal in 2009 and joined the faculty in 2011. David has received many prestigious awards and honours such as Scientist of the Year 2008 – Société Radio-Canada, the 2010 AAAS Newcomb Cleveland Prize, the 2010 NSERC John C. Polanyi Award, and the Medal of Honours of the Assemblée Nationale, Province de Québec.
Dr. Lafrenière is an expert in the field of exoplanet imaging who has made a substantial and significant impact very early in his career. He is among the few people to have led the first imaging discoveries of exoplanets. David’s early work on 1RXSJ1609-2105b has yielded one of the best spectroscopic/photometric datasets ever secured on a gas giant exoplanet. He is the inventor of a mathematically rigorous statistical method called the Locally Optimized Combination of Images (LOCI) algorithm, which was designed to improve contrast achieved in astronomical images. LOCI has become the worldwide gold standard in the analysis of high-contrast images. He also conducted the Gemini Deep Planet Survey (GDPS), the first statistically significant exoplanet imaging survey, which provided one of the best constraints ever obtained on the gas giant planet frequency in wide orbits around main sequence stars. He was a member of the team that first imaged a multi-planet system orbiting another star (HR8799). He is currently the leader of a major exoplanet transit and eclipse spectroscopy program for the Canadian-built NIRISS instrument on the James Webb Space Telescope. It has been said that, if a space mission does one day detect an Earthlike planet and reveal oxygen in its atmosphere, it will do so using techniques descended from Dr. Lafrenière’s LOCI.
In addition to his impressive scientific and technical achievements, it is worth noting Dr. Lafrenière’s extensive service to the Canadian astronomical community. Indeed, he has served on a number of important committees (e.g., JCSA, CanTAC) as well as on science teams for cutting-edge instruments with significant Canadian involvement such as CFHT/SPIROU, Gemini/GPI, and JWST/NIRISS.
Please join CASCA in congratulating Dr. Lafrenière for being awarded the Richer Medal in recognition of his significant and sustained early career research in astronomy.
CASCA is pleased to announce that the recipient of the 2017 Peter G. Martin award is Dr. Ingrid Stairs of the University of British Columbia.
After receiving her PhD in 1998 from Princeton University, Dr. Stairs went to the University of Manchester from 1998 to 2000 to pursue postdoctoral work. She then continued her research at the National Radio Astronomy Observatory from 2000 to 2002 as a Jansky Fellow. She joined the faculty at UBC in 2002 and became a tenured professor in 2007. The Canadian Institute for Advanced Research appointed her as Senior Fellow in 2014.
Dr. Stairs is one of world’s experts on pulsars and has made significant contributions to radio astronomy instrumentation. She developed the novel Princeton Mark IV back-end instrument for use at the Arecibo telescope for high-precision timing of relativistic pulsars that was used in the discovery of general-relativistic orbital decay of the binary pulsar PSR B1534+12. She made the first measurement of the Shapiro delay, which continues to enable multiple new tests of General Relativity. She is involved in the development of instrumentation for the upcoming CHIME radio telescope that will observe pulsars as well as the cosmological distribution of hydrogen. She is the Observational Coordinator for the North American Nanohertz Observatory for Gravitational Waves (NANOGrav).
CASCA congratulates Dr. Stairs on the receipt of the 2017 Martin Award for her fundamental contributions to radio astronomy instrumentation and the understanding of pulsars that have shed new light on General Relativity.
