We study how the predicted [α/Fe]–[Fe/H] relations in early-type galaxies vary as functions
of their stellar masses, ages, and stellar velocity dispersions, by making use of cosmological
chemodynamical simulations with feedback from active galactic nuclei. Our model includes
a detailed treatment for the chemical enrichment from dying stars, core-collapse supernovae
(both Type II and hypernovae) and Type Ia supernovae. At redshift z = 0, we create a
catalogue of 526 galaxies, among which we...[Show more]
