Friday 09 Nov 2012: Colloquium: The Physics of Galaxy Formation: recreating a virtual universe
Prof. Richard Bower - Durham University
Newman F 12:00-13:00
I'll start my talk by reviewing the puzzle of galaxy formation. There are essentially
three problems: why are so few baryons (<10%) able to cool and form stars?
why is there such a sharp cut off in the masses of galaxies? why is are the
largest galaxies old and red? I'll show how including the physics of black-hole
growth can reconsile these issues with the Lambda-CDM model. There are, however,
many problems that still remain to be solved: the interaction of galaxies
with their environment and the deficit of baryons in the haloes of groups and
clusters. I'll provide a hint of recent progress in these areas.
