« The VESTIGE survey: reconstructing the star formation history of massive early-type galaxies through their UV and Halpha emission »
Galaxies undergo remarkable morphological transformations, and it is still unclear how they change their shape from disks to spheroids, how they build up their mass and cease forming stars. It is now well established that the observed wide range of morphologies and evolutionary stages of galaxies strongly depend on the environment, from dense cluster cores to filaments and voids. Environmental processes play indeed a key role in transforming galaxies, particularly through mechanisms such as tidal interactions, galaxy harassment, and ram-pressure stripping. However, the relative significance of these processes and their impact on gas removal and star formation remain open questions.
