Seminar
The parallelism between early-type galaxies and clusters

Abstract

I will review the properties of nearby early-type galaxies and galaxy clusters showing the most interesting observed parallelisms, such as the Sersic behavior of the light profiles, the color-magnitude diagram and the main scaling relations. I will show a comparison with the data extracted from the ILLUSTRIS simulation and present the constraints to the star formation history that are necessary to obtain a reliable distribution of galaxies in the color-magnitude diagram.
