Evolutionary properties of our model cluster. Top panel: Mass (solid black curve) and accretion rate (dashed grey curve) vs redshift for a cluster with M_cl = 5 × 10¹⁴ M_⊙ at z = 0.055. The blue square and the red circle show the median M_cl and redshifts of the EDisCS and OmegaWINGS clusters, respectively, with the error bars corresponding to half the difference between the 84th and 16th percentiles of the galaxy distribution. Bottom panel: Morphology fractions for field galaxies that join the cluster as a function of z, assumed to be independent of the galaxy M_★.
