Detailed stellar population analysis of galaxy clusters at increasing redshift: A constrain for their evolution

Abstract

This contribution describes a project of a detailed stellar population analysis for different clusters of galaxies with increasing redshift. The selected clusters are selected from the GEMINI/HST Galaxy Cluster Project. GMOS spectra and HST imaging are avaiable for all of them. The signal-to-noise ratio of the spectra allow us to analyse the stellar population of individual Galaxies, allowing us to study trends with morphological type or distance to the center of the cluster. Here we intend to show the different techniques we are planning to apply in this study to derive kinematics, ages, metallicities and star formation histories for the idividual galaxies in each clusters. Furthermore, an analysis of all this properties with the redshift is planned to constrain the evolution of the galaxies. © Springer-Verlag Berlin Heidelberg 2011.
