Dissipative phenomena in Local Group dwarf galaxies evolution and their synthetic CMDs
Abstract
Galaxies result from a complex interplay between dark-matter-driven hierarchical structure formation and feedback-controlled conversion of the baryonic matter into stars. The smaller (in mass) examples of these systems are the "dwarf"-galaxies. Dwarf galaxies are the most common type of galaxies in the universe and dominate by number the population of galaxies in clusters, groups, and so around our Galaxy, i.e. the Local Group (LG). In this work we present a method to investigate the interplay between environment and internal processes in the star formation history of dwarf galaxies neighbouring a hosting system, i.e. the dissipative phenomena ruling the star formation history of a dwarf galaxy.
