Galaxy evolution in groups and clusters: satellite star formation histories and quenching time-scales in a hierarchical Universe by Wetzel, Andrew R., Tinker, Jeremy L., Conroy, Charlie, van den Bosch, Frank C.

“…Satellite galaxies in groups and clusters are more likely to have low star formation rates (SFRs) and lie on the 'red sequence' than central ('field')…”
