A combined VANDELS and LEGA-C study: the evolution of quiescent galaxy size, stellar mass and age from \mathbf{\textit{z} = 0.6} to \mathbf{\textit{z} = 1.3}

We study the relationships between stellar mass, size and age within the quiescent population, using two mass-complete spectroscopic samples with \mathrm{log_{10}}(M_{\star}/\mathrm{M_{\odot}})>10.3, taken from VANDELS at 1.0<z<1.3, and LEGA-C at 0.6<z<0.8. Using robust D_{n}4000 values, we demonstrate that the well-known 'downsizing' signature is already in place by z\simeq1.1, with D_{n}4000 increasing... Show more
