Hydrodynamic simulations of the formation of galaxies

Great progress has recently been achieved in simulating the formation and evolution of galaxies. In this case initial conditions, consisting in a scalar field of density perturbations, are set by the standard cosmological model, but the processes that shape the formation of galaxies as we know them take place on such a wide range of scales that a large number of these processes must be treated with sub-resolution techniques. I will review recent attempts to model the formation of galaxies, with emphasis on feedback processes from young and dying stars and from accreting supermassive black holes, that are most relevant for reproducing plausible galaxies, and will show recent progress on the panchromatic modelling of their spectral energy distributions.
