A review of the results of the Near-IR S0 galaxy Survey (NIRS0S) is presented. NIRS0S is a magnitude (mB 12.5 mag) and inclination ( 65o) limited sample of 200 nearby galaxies, mainly S0s. It uses deep Ks -band images, typically reaching a surface brightness of 23.5 mag arcsec^(-2) . Detailed visual and photometric classifications were made, for

We present our recent results on the properties of the outskirts of disk galaxies. In particular, we focus on spiral galaxies with stellar disk truncations in their radial surface brightness profiles. Using SDSS, UDF and GOODS data we show how the position of the break (i.e., a direct estimator of the size of the stellar disk) evolves with time

The luminosity function is not only crucial to know stellar density distribution in space, and thus to know the structure of the Galaxy, but it allows the determination of the stellar mass function using the mass-luminosity relationship. The luminosity function and mass function are fundamental to the understanding of star formation and the

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 Kinematic Groups are kinematical coherent groups of stars which may share a common origin. These groups spread through the Galaxy over time due to tidal effects caused by galactic rotation and disk heating, however some chemical information remains unchanged. The aim of chemical tagging is to show that abundances of every element in the
