Evolution of the Stellar Mass-Metallicity Relation. II. Constraints on Galactic Outflows from the Mg Abundances of Quiescent Galaxies

Nicha Leethochawalit, Evan N. Kirby, Richard S. Ellis +2

We present the stellar mass-[Fe/H] and mass-[Mg/H] relation of quiescent galaxies in two galaxy clusters at $z\sim 0.39$ and $z\sim 0.54$. We derive the age, [Fe/H], and [Mg/Fe] for…
