Dr. Allison Man is an assistant professor at the University of British Columbia. She investigates the physics behind starbursts, colliding galaxies and supermassive black holes. Allison received her PhD in Astrophysics from the University of Copenhagen. Prior to joining UBC, she was an ESO Fellow at the European Southern Observatory Headquarters and a Dunlap Fellow at the Dunlap Institute for Astronomy and Astrophysics at the University of Toronto.
Talk Title and Abstract:
The Rise and Fall of Star Formation in Galaxies
Star formation and supermassive black hole growth were most active at cosmic noon (z~2). Massive galaxies appear to experience accelerated growth at early cosmic times, and eventually quench their star formation and become more bulge-dominated. Exactly why these transformations take place is unclear. Mergers and active galactic nuclei feedback are often invoked as explanations, but a consensus is yet to be reached. I will discuss how multiwavelength observations of stellar populations and multiphase gas of distant galaxies can shed new light on the complex problem of galaxy evolution.
