Les amas dans la toile cosmique / Clusters in the cosmic web


Scientific rationale

Galaxy clusters are at the intersection of cosmic filaments and numerical simulations show that they can be considered as still forming, in the sense that they are interacting with their environment. This is confirmed by the fact that in some cases filaments have been detected between clusters. The aim of this workshop is to update our knowledge on how infall of matter from the cosmic web and group-cluster or cluster-cluster merging affect the properties of the galaxies, X-ray gas and dark matter contained in clusters.
