How gas flows in and out of galaxies is one of the central questions in galaxy formation and evolution. Gas is the fuel for star formation, and there are several physical processes – both internal and external to the galaxy – that can affect the gas content and drive the subsequent galaxy history.
I will present the GASP (Gas Stripping Phenomena in galaxies) survey, an ESO Large Program with MUSE studying ~120 galaxies at z=0.04-0.07 in clusters, groups and filaments aimed at studying the mechanisms of gas removal and their effects on the star formation activity. I will provide an overview of the survey results so far, and focus on two of these: the characteristics of the star formation taking place in the long tails of gas stripped by ram pressure, and the relation between ram pressure and triggering of an AGN.
