Oral title: Formation and properties of galactic bulges in MW-sized haloes in the AURIGA simulations Oral abstract: We study the formation and properties of galactic bulges in the Auriga simulations, a suite of forty cosmological magneto-hydrodynamical zoom-in simulations of late-type galaxies in MW-sized Dark Matter haloes performed with the moving-mesh code AREPO. We aim to characterize the formation mechanisms of bulges of an unprecedented large number of galaxies simulated with high levels of resolution in a cosmological context. The bulges of the Auriga galaxies show variety in their shapes, sizes and formation histories. A few of them resemble the X-shape of the MW bulge. Most of the Auriga bulges have less than 25% of accreted stellar particles. We search for correlations between bulge properties such as major-to-minor axis ratios, metallicities, ages, and accretion fraction to define observable properties that will help constraining bulges' origins. Our results are well-suited to compare with current observations of the Milky Way bulge and shed light into its formation.
