Ten years of MUSE GASP discoveries

GASP (GAs Stripping Phenomena in Galaxies) was the first MUSE Large Program approved. With over 70 papers published based on the MUSE data, GASP has shown the outstanding capabilities of MUSE, also in combination with multi-wavelength ground and space-based follow-ups with ALMA, APEX, HST, ASTROSAT and other facilities. I will summarize the highlights of the GASP program, which have represented breakthroughs for understanding the physical processes that affect gas in galaxies. GASP has studied galaxies in clusters, groups, filaments and isolated at z=0.04-0.07 over a wide galaxy stellar mass range. In clusters, it has provided the first large sample of confirmed ram-pressure stripped galaxies in various stages and degrees of stripping. Highlights include the star formation activity, stellar history and quenching, the properties of star-forming clumps and diffuse gas, the AGN incidence, the gas metallicities in disks and stripped tails and the consequences of ram pressure for galaxy morphologies and structure. Outside of clusters, the GASP MUSE data has revealed cases of gas accretion, cosmic web effects (stripping and star formation enhancement), starvation and also ram pressure outside of clusters. I will present an overview of the results and will depict ways forward for advancements in the field that can only be reached with MUSE.
