Abstract

The main goal of this work is to study and analyze collisions between galaxy groups and clusters using numerical simulations and observations in optical and X-rays. These collisions last for about several billion years and involve energies that can reach up to about $10^{64}$~Ergs. The study of these collisions reveals how the largest structures formed in the Universe. By constructing a sample of colliding groups and clusters based on X-ray and optical spectroscopic data, we will model these systems using the Gadget-IV code, taking into account dark matter and the intracluster gas. A better understanding of these interacting complex systems will provide important insights into the processes involved in the formation and evolution of large-scale structures in the Universe.
