Star Talk: Quasars – Black Holes You Can “See”

“Quasars – Black Holes You Can ‘See'” with Dr. Patrick Hall

Date & Location: 7:00 PM-8:00 PM Oct. 24, McLennan Physical Laboratories (MP), Room 102, 60 St. George St., Toronto, ON M5S 1A7

Telescope observing: 8:00 PM-9:00 PM on 14th floor of McLennan Physical Laboratories (MP) (weather permitting) — you will be guided to the telescopes.

Abstract: Quasars are the brightest objects in our Universe. A quasar is a rotating disk as big as our solar system and hotter than the Sun, formed when matter spirals into a supermassive black hole at the centre of a galaxy. Dr. Hall will discuss these fascinating objects and how they tap the strong gravity of black holes.

About the Speaker: This star talk features Dr. Patrick Hall, a Ph.D. graduate in astronomy and astrophysics. Dr. Hall is currently a professor at York University and a contributor to the SAO/NASA Astrophysics Data System. He specializes in quasars and blackholes, particularly in the outflows of gas and light from these active bodies.
