Calura, F; Gibson, Bradley K; Michel-Dansac, L; Stinson, G S; Cignoni, M; Pilkington, K; Dotter, Aaron; Bailin, Jeremy; Couchman, H M P; Wadsley, J


By means of high-resolution cosmological hydrodynamical simulations of Milky Way (MW) like disc galaxies, we conduct an analysis of the associated stellar metallicity distribution functions (MDFs). After undertaking a kinematic decomposition of each simulation into spheroid and disc subcomponents, we compare the predicted MDFs to those observed in the solar neighbourhood and the Galactic bulge. The effects of the star formation density threshold are visible in the star formation histories,...[Show more]
