“Snacking, Gorging, and Cannibalization: The Feeding Habits of Black Holes”
Steve Croft, PhD, Astronomy Department, University of California, Berkeley
Dr. Steve Croft studies black holes using a wide range of telescopes, including Hubble, the Shane Telescope at Lick Observatory, Keck, and most recently the Murchison Widefield Array in the remote Western Australian outback. In this talk, Croft will share information about a new generation of telescopes with the capability to tell us about how black holes grow: by cannibalizing each other in stupendous mergers; by swallowing huge volumes of ten million degree gas; and by shredding and consuming stars that happen to pass too close.
Dr. Croft grew up in England, where he received a PhD in astrophysics from Oxford University in 2002, before moving to California to work as a postdoctoral researcher at the Lawrence Livermore National Laboratory. Since 2007, Croft has been a researcher in the Astronomy Department at UC Berkeley, and is also involved in outreach, including for Berkeley SETI Research, and informal education, including the NASA NOVAS program.
