15 billion years of galaxy cluster evolution in the Coma and Leo superclusters
Galaxy supercluster represent an environment for coevolution of galaxies and galaxy clusters. I talk about our recent study of the richest galaxy clusters in the Coma and Leo superclusters (A1656, A1367, and A1185), their substructure and galaxy content, connectivity (the number of filaments connected to a cluster), and mass distribution in and around clusters. Using spherical collapse model we estimated the evolutional track of clusters from formation to virialization (altogether during 15 billion years).
