On the [α/Fe]–[Fe/H] relations in early-type galaxies

Vincenzo, Fiorenzo; Kobayashi, Chiaki; Taylor, Philip

Description

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]
