Abstract: Forming realistic late-type galaxies is a very challenging problem in cosmological simulations of galaxy formation. In this talk, I show the latest results on this topic for the moving-mesh code AREPO by presenting a series of hydrodynamic zoom simulations of eight haloes previously studied in the Aquarius project. These simulations feature a significantly improved version of the baryon physics modules including metal cooling, a self-consistent treatment of the stellar evolution and the associated mass and metal return to the gaseous phase, galactic winds and AGN feedback. They demonstrate the ability of AREPO in producing discs that agree well with the scale relations and the observed properties of late-type galaxies. Moreover, without any change the parameters of our feedback loops, the resulting galaxy properties are scarcely affected by numerical resolution in contrast to other modeling techniques that are intrinsically resolution depenedent. As a final point, I will also briefly discuss some preliminary results on the inclusion of magnetic fields --via ideal MHD -- in these simulations.
