Abstract

The interaction of gas rich galaxies via mergers or close encounters can give rise to sudden, violent star formation (SF), often accompanied by the presence of an AGN. The merger gives rise to a system whose energy is mostly emitted in the IR with a luminosity above 10E11 L_sun. These dusty environments are the scenery of supernova explosions at a high rate as well as of super-massive black hole (SMBH) growth and at the same time, they represent excellent laboratories to study the evolution of galaxies. In this talk I will guide you trough a journey of the different science that can be done when studying mergers and I will present exciting observations on a “baby” AGN and a tidal disruption event.
