The Auriga Project is a large suite of high-resolution magneto-hydrodynamical simulations of Milky Way-sized galaxies, simulated in a fully cosmological environment by means of the ‘zoom-in’ technique. It is simulated with the state-of-the-art hydrodynamic moving mesh code AREPO, and includes a comprehensive galaxy formation model based on the successful cosmological simulation Illustris.

An important ste""p towards our understanding of galaxy formation is to simulate successfully the formation and evolution of Milky Way mass, disc galaxies in a fully cosmological context. From a cosmological perspective, Milky Way mass disc galaxies are of particular interest because they lie between the low and high mass regimes thought to be dominated by supernova and active galactic nuclei (AGN) feedback,respectively, and are therefore ideal targets to test the models of feedback designed to reproduce whole galaxy populations.
