Experimental Computational Simulation of a Galaxy Cluster

Abstract

Galaxy clusters are large structures composed of galaxies, intra-cluster gas, and dark matter. The kinematics of their constituent galaxies are still studied observationally, although computational experiments serve as true simulation laboratories, reproducing observational aspects in these systems. In fact, while astrophysicists observe two-dimensional projections of three-dimensional objects in the sky with telescopes, computer models simulate three-dimensional systems, using the laws of physics in an attempt to recover observational aspects. In light of the above, this work focuses on the computational simulation of a galaxy cluster, examining its dynamic stability, the physical aspects of its galaxies, and the observational counterpart of its member galaxies.
