Descrizione
Galaxy clusters are key environments for studying galaxy evolution. While environmental effects on galaxy properties are evident, the mechanisms behind quenching and structural transformations remain debated.
In this talk, I will present the study of the cluster Abell S1063 at z = 0.346 using optical and near-infrared data from VST-GAME and VISTA surveys, respectively. The unique grasp of VST and VISTA, together with the availability of about 1500 cluster members, allow to performe an
unprecedented investigation of physical processes responsible for galaxy evolution across different
environments, from the dense cluster core to the periphery, out to about 5Rvir (~10Mpc). We compared cluster member properties across regions with different local densities, ranging from the cluster center to filaments.
We also analyse JWST data from the GLIMPSE program (P.I. Atek H.), in which Abell S1063 was observed in nine bands. These data represent a goldmine to estimate the stellar evolution parameters (mass, age, and star formation) of the galaxies in the cluster.
