Title:
Modeling the formation of Super-Massive Black Hole Seeds in the Early Universe
Time:

Location:
Room H2.32, O'Brien Centre for Science

Abstract

Black Holes with masses of 10^9 Msolar have been observed to exist less than 1 billion years after the Big Bang. Under Eddington limited accretion the timescale for growing from a seed mass of 100 Msolar (approximate mass of the first stars) to 10^9 Msolar would appear to be extremely challenging given the time constrains. I will present an alternative scenario where extremely massive stars can be formed under the correct conditions in the early Universe satisfying the number density requirements of the super massive black holes observed.
