 Project objective

The build up of galaxies is mainly driven by the availability of gas that can cool and form new stars. Any physical process that is able to alter the gas content of a galaxy has therefore important consequences for its evolution. The study of processes that can remove gas from galaxies is the subject of GASP (GAs Stripping Phenomena in galaxies), an ESO Large Program I am leading. GASP has obtained integral field spectroscopy (IFS) with MUSE of 114 low-z galaxies with masses in the range 10^9-10^11.5 Msun, hosted in X-ray selected clusters, in groups and filaments. The GASP sample includes the largest existing IFS sample of so- called “jellyfish galaxies” that have long tails of ionised gas, as well as other galaxies in different stages of ram pressure stripping in clusters and galaxies undergoing gas disturbance due to various phenomena in groups and filaments. GASP has the unique capability to combine the power of spatially resolved observations covering galaxy disks, outskirts and surroundings with the virtues of a statistical study of a significant number of galaxies. The MUSE GASP dataset, combined with ALMA, APEX, JVLA, UVIT and HST follow-up programs, form the basis for this ERC program. The goal is to accomplish an unprecedented break-through in our understanding of jellyfish galaxies, ram pressure stripping, gas removal processes in different environments and their consequences for the stellar history of galaxies. This multi faced, coherent program will investigate the physics of the baryonic cycle between the various gas phases (ionised, molecular and neutral) and the star formation under extreme conditions, the connection between ram pressure and AGN activity, the quenching of galaxies undergoing gas removal phenomena, and the physics of such phenomena in clusters, groups and filaments. The GASP ERC program will be a game changer in this field of research: there is no previous similar study, nor there can be a comparable one for quite a long time.

Are you the coordinator (or a participant) of this project? Plaese send me more information about the "GASP" project.

For instance: the website url (it has not provided by EU-opendata yet), the logo, a more detailed description of the project (in plain text as a rtf file or a word file), some pictures (as picture files, not embedded into any word file), twitter account, linkedin page, etc.

Send me an  email ( and I put them in your project's page as son as possible.

Thanks. And then put a link of this page into your project's website.
