Galaxies living in rich environments are suffering different perturbations able to drastically
affect their evolution. Among these, ram pressure stripping, ie the pressure exerted by the …

The diffuse light that spreads through groups and clusters of galaxies is made of free-floating
stars not bound to any galaxy. This is known as the intracluster light (ICL) and holds …

One of the key open questions in extragalactic astronomy is what stops star formation in
galaxies. While it is clear that the cold gas reservoir, which fuels the formation of new stars …

We use the IllustrisTNG hydrodynamical simulations to show how the fractions of quenched
galaxies vary across different environments and cosmic time, and to quantify the role AGN …

Jellyfish galaxies are prototypical examples of satellite galaxies undergoing strong ram
pressure stripping (RPS). We analyse the evolution of 512 unique, first-infalling jellyfish …

We introduce the Hydrangea simulations, a suite of 24 cosmological hydrodynamic zoom-in
simulations of massive galaxy clusters (M 200c= 1014–1015.4 M⊙) with baryon particle …

We present predictions for the quenching of star formation in satellite galaxies of the Local
Group from a suite of 30 cosmological zoom simulations of Milky Way-like host galaxies. The …

The star formation and gas content of satellite galaxies around the Milky Way (MW) and
Andromeda (M31) are depleted relative to more isolated galaxies in the Local Group (LG) at …

We investigate the effect of ram-pressure from the intracluster medium on the stripping of H i
gas in galaxies in a massive, relaxed, X-ray bright, galaxy cluster at z= 0.2 from the Blind …

Galaxy groups are more than an intermediate scale between clusters and halos hosting
individual galaxies, they are crucial laboratories capable of testing a range of astrophysics …
