Modelling the quenching of star formation activity from the evolution of the colour-magnitude relation in VIPERS
We study the evolution of the colour-magnitude relation for galaxies in the VIMOS Public
Extragalactic Redshift Survey (VIPERS) by introducing the concept of the bright edge, and
use this to derive constraints on the quenching of star formation activity in galaxies over the
redshift range 0.5< z< 1.1. The bright-edge of the colour-magnitude diagram evolves with
little dependence on galaxy colour, and therefore on the amount of star formation taking
place in bright galaxies. We modelled this evolution with delayed exponential star formation …
