Galaxy cluster collisions

Massive galaxy clusters, the largest collapsed objects in the Universe, are built both through major mergers and gentle accretion. The study of cluster collisions provides us a way to better understand the large-scale structure formation and evolution. In this talk I'll present some recent work based on X-ray and optical data on a few colliding clusters. The dynamical modeling is done with hydrodynamical N-body simulations. We'll discuss the case of Abell 3376, a bullet-like cluster at low redshift, the sloshing of Abell 2052 intracluster plasma, and the complex system Abell 1758.
