Title: Simulating galaxy formation: numerical and physical uncertainties
Date: Wednesday, April 9th, 2014
Time: 11:30
Venue: Villa Bazzoni

Abstract: Hydrodynamical cosmological simulations are one of the most powerful tools to study the formation and evolution of galaxies in the fully non-linear regime. Despite several recent successes in simulating Milky Way look-alikes, self-consistent, ab-initio models are still a long way off.
In this talk I will review numerical and physical uncertainties plaguing current state-of-the-art cosmological simulations of galaxy formation. I will then present global properties of galaxies as obtained with novel cosmological simulations with the moving mesh code Arepo and discuss which feedback mechanisms are needed to reproduce realistic stellar masses and galaxy morphologies in the present day Universe.
