Abstract: Cosmological simulations of galaxy formation have come a long way towards producing a population of galaxies that is similar in many aspects of the observed population. We understand how the dark matter haloes that host galaxies form and evolve, and how gas cools inside these haloes to grow discs that fragment into stars. However it is clear that feedback from stars, probably in the form of energy injected by supernovae, plays a crucial role in shaping galaxies. For massive galaxies, energy injected by super massive black holes may play an equally important role. These processes are challenging to model due to the large range in time and length scales involved. I will present some results from a set of hydrodynamical cosmological simulations, called Gimic and Owls, and show how our modelling of feedback results in realistic looking galaxies. The simulations also allows us to examine other aspects of structure formation, for example the relation between gas and galaxies. I will also point-out limitations of the models, and conclude with some preliminary results of a new suite of simulations called Eagle.
