Abstract

The aim of this project is the study of the large-scale distribution of galaxies around rich clusters. At this scale of tens of Mpc, the galaxy distribution reflects the mass distribution (mainly dark matter) in cosmic filaments and superclusters. We will investigate whether the physical properties of collapsed clusters maintain any relation with their non-collapsed neighborhood, which should still have a "memory" of the linear evolution phase of the primordial density fluctuations.
