Title: "Constraining mass and shape of galaxy clusters through large scale structures"

Supervisor: Steen H. Hansen

I discuss a new method to measure the mass of galaxy clusters connecting the gravitational potential of the cluster with the kinematical properties of its surroundings. We identify groups  of galaxies, as sheets or filaments, in the cluster outer region, and model how the cluster  gravitational potential perturbs the motion of these structures from the Hubble flow, by looking at their radial infall velocity profile. We test the method on cosmological simulations and then on Coma galaxy cluster.
