The stellar metallicities of massive quiescent galaxies at 1.0 < z < 1.3 from KMOS+VANDELS

We present a rest-frame UV-optical stacked spectrum representative of quiescent galaxies at 1.0 < z < 1.3 with log(M_*/\rm{M_\odot}) > 10.8. The stack is constructed using VANDELS survey data, combined with new KMOS observations. We apply two independent full-spectral-fitting approaches, obtaining consistent stellar ages and metallicities. We measure a total... Show more
