La conférence Petrie est un discours invité prononcé tous les deux ans par un astrophysicien remarquable à l’occasion du congrès annuel de la Société, commémorant l’importante contribution à la recherche en astrophysique du défunt Robert M. Petrie. La conférence Petrie est née sous les auspices du Comité national canadien de l’UAI, avant même l’existence de la Société, et fut relancée par la Société en 1977 comme un événement régulier. Les nominations pour la conférence Petrie peuvent être effectuées en tout temps en soumettant le nom du nominé au comité des prix et médailles, et doivent être proposées par au moins deux membres de la CASCA en bonne et due forme. Les nominations pour la conférence de 2021 doivent être reçues d’ici le 31 decembre 2020.
Conférence R.M. Petrie 2019
The 2019 R. M. Petrie Prize is awarded to Dr. Gabriela Gonzalez.
Dr. Gonzalez is a professor of physics and astronomy at the Louisiana State University and has been a member of the LIGO Scientific Collaboration (LSC) since 1997. Her group has been involved in noise-characterization and calibration of the LIGO detectors, as well as data analysis. Dr. Gonzalez was the spokesperson for the LSC from March 2011 until March 2017, and in that role oversaw the ground-breaking discovery of the first gravitational wave source with Advanced LIGO. She is a fellow of the Institute of Physics, the American Physical Society and was elected to the National Academy of Sciences in 2017.
CASCA is honoured to have Dr. Gonzalez give the Petrie Prize lecture.
