Abstract

In this project, we aim to contribute to the understanding of the formation and evolution of the structures of the universe through the study of galaxy clusters, the largest gravitationally bound systems. The formation process of these clusters involves complex phenomena such as massive mergers, accretion of galaxy groups, and galactic interactions with the interstellar medium and among themselves. We intend to determine the structural and morphological properties of galaxies located in clusters using images in the $g$, $r$, and $z$ bands from the Legacy DESI survey, as well as to determine the physical properties of ionized gas, such as metallicity, and characteristics of the stellar population of galaxies located in clusters obtained using spectroscopic data from the Sloan Digital Sky Survey. These estimates will be correlated with events such as tidal interactions and ram pressure stripping, the spatial position of galaxies in the cluster, in addition to the structural properties of galaxies, among others.
