Newcomers and suburbanites can drive the evolution of the size-stellar mass relation of early type galaxies in galaxy clusters

Massimiliano Matteuzzi, Federico Marinacci, Carlo Nipoti +1

At fixed stellar mass $M_{\ast }$, the effective radius $R_{\mathrm{e}}$ of massive satellite early-type galaxies (ETGs) in galaxy clusters is, on average, larger at lower redshift. We study…
