About this document

Stellar Metallicity in z ∼1.4 Galaxies by Ianjamasimanana Roger is a document available to read on EtoBox.

This document presents the results of a study measuring the metallicities and elemental abundance ratios of five massive quiescent galaxies at z ~ 1.4. The study derives [Mg/Fe] and [Fe/H] ratios for three galaxies, finding that [Mg/Fe] appears correlated with stellar mass while [Fe/H] is approximately constant with mass, similar to lower-redshift findings. However, [Fe/H] at z ~ 1.4 is ~0.2 dex lower than at z < 0.7. The most massive galaxy may have a higher [Mg/Fe] than similar galaxies at lower redshifts
