Evidence for a change in the dominant satellite galaxy quenching mechanism at<i>z</i> = 1
We present an analysis of galaxies in groups and clusters at 0.8 < z < 1.2, from the GCLASS and GEEC2 spectroscopic surveys. We compute a 'conversion fraction' fconvert that represents the fraction of galaxies that were prematurely quenched by their environment. For massive galaxies, Mstar > 1010.3 M⊙, we …
