Abstract

The way galaxies form and evolve throughout the cosmic time remains one of the greatest challenges of modern cosmology. Galaxy formation involves many different physical mechanisms that leave typical imprints in the luminous matter. Therefore, the stellar content of galaxies can provide a wealth of information on how these systems were assembled. In this project, we propose to study stellar populations in galaxies with different masses and in different environments, in order to put constraints on galaxy formation models. Considering the large amount of spectral data that will be available in the near future, we will implement STARLIGHT (spectral fitting code) in a VO-like environment, making stellar population analysis more efficient and reliable. We will also conduct preliminary studies for the use of future instruments, such as OPTIMOS­-EVE to detect cold gas being accreted tohigh­redshift galaxies.
