To help identify the role of large scale structure in galaxy evolution, we selected a sample of 21 galaxy systems that span a wide range in halo mass. The figure below (from Balogh et al. 2020, submitted) shows halo masses estimated from velocity dispersion, as a function of redshift. It includes systems from GCLASS (Muzzin et al. 2012) and GEEC2 (Balogh et al. 2014).
