Abstract: To understand galaxy evolution we need to understand the connection between Supermassive Black Holes (SMBHs) and their host galaxies; to this aim, we need tools that can trace this connection at high redshift and in active galaxies, and to understand how SMBHs affect the properties of their host galaxies in the local universe. I present my work on this subject from two different points of view. I tested the best tracer for the stellar velocity dispersion sigma* between the three gas emission lines [OIII], [NII] and Halpha using the SDSS database, in order to give a tool for the study of the M_bh-sigma* relation even in high redshift and active galaxies. Second, I studied a sample of both Cool Core and Non Cool Core Cluster galaxies to test that multiwavelength broad band colors are able to retain the recent star formation in CCC galaxies; this will give the possibility to measure the mean star formation rate difference between CCC and NCCC galaxies and to obtain some clues on the efficiency of AGN feedback in quenching star formation.
