Abstract

Based on the double exponential behaviour of the gas mass profile and on the O/H gradient, Robles-Valdez, Carigi & Peimbert (2013) built a sucessful chemical evolution model for M33. The model predicts that in the inner parts of M33 the star formation history follows an inside-out scenario, like M31 or the MW, but in the outer parts of M33 the star formation history follows an outside-in scenario, as dwarf galaxies of the Local Group.

Abstract

ΛCDM-based numerical simulations predict a scenario consistent with observational evidence in Milky Way-like halos. However, less clear is the role of low-mass galaxies in the big picture. The best way to answer this question is to study the nearest example of a dwarf spiral galaxy, M33. We will use star clusters to understand the structure, kinematics and stellar populations of this galaxy. We will present our current status and future plans of a comprehensive study of the star cluster system of M33. This study will provide key insights into the star formation history, composition and kinematics of low-mass galaxies as well as place M33 within the context of galaxy formation process.

Abstract

We are going to present a new code to derive the SFH of a complex stellar population system, like a galaxy. This code has been used to obtain the SFH of six dwarf galaxies from the Local Constrains form Isolated Dwarf (LCID) project for which we are presenting the first results. The project has been designed to obtain the SFH of isolated dwarf galaxies free from strong interactions with massive host galaxies, like the MW or M31. The results obtained could help us to understand the spatial structure of dwarf galaxies and how galaxies form and evolve.
