Roles and responsibilities
Astrophysicist, Plaskett fellow, and Science Co-lead and Science Planning Tools Lead for the Cosmological Advanced Survey Telescope for Optical and UV Research (CASTOR). Research expertise on cosmic explosions, interacting stars, supernovae, the interstellar medium, and the formation & growth of supermassive black holes in the early Universe.
Current research and/or projects
Discovering the origin of supermassive black holes: We now know that a supermassive black hole lies at the heart of every galaxy, including our own. We still don't understand, however, how such black holes, with masses up to a billion times the mass of our Sun, could have formed. To solve this problem, we're combining cutting-edge computer simulations of the primordial Universe with observations from next-generation space telescopes including the James Webb Space Telescope.
Uncovering the causes of cosmic explosions: We still don't know why some white dwarfs, the otherwise stable end states of stars like our own Sun, sometimes explode as cataclysmic events called Type Ia supernovae, that briefly outshine the galaxies in which they reside. By combining observations from telescopes on the ground and in space with detailed numerical simulations, we're piecing together the origins of long-ago exploded supernovae, and understanding more about how they came to be and their critical role in the evolving composition of the Universe.
The next generation in Canadian Space Astronomy: Canada is leading the way forward for the next generation of UV/optical observations from space, with the development of the Cosmological Advanced Survey Telescope for Optical and UV Research (CASTOR). With a proposed launch by the end of the decade, CASTOR will be a Canadian-led flagship space telescope. With Hubble-like resolution over a field of view 100x larger than Hubble's, CASTOR will be humanity's foremost eye on the sky in the UV, exploring the births of stars, the lives of galaxies, and the growth of supermassive black holes over cosmic timescales.
