We present a spectro-photometric study of a mass-complete sample of quiescent galaxies at 1.0 < z < 1.3 with \mathrm{log_{10}}(M_{\star}/\mathrm{M_{\odot}}) \geq 10.3 drawn from the VANDELS survey, exploring the relationship between stellar mass, age and star-formation history. Within our sample of 114 galaxies, we derive a stellar-mass vs stellar-age relation... Show more
