Mapping the working of environmental effects in A963

Popis výsledku v původním jazyce

We qualitatively assess and map the relative contribution of pre-processing and cluster related processes to the build-up of A963, a massive cluster at z=0.2 showing an unusually high fraction of star forming galaxies in its interior. We report the first tentative observations at 21 cm of ongoing ram-pressure stripping at z=0.2, as well as observed inflow of low-entropy gas into the cluster along filaments of the large-scale structure.Conclusions. The observed galaxy content of A963 is a result of strongly anisotropic accretion of galaxies with different properties. Gas rich, star forming galaxies are being accreted from the east and west of the cluster and these galaxies are being quenched at r< R-200, likely by ram-pressure stripping. The bulk of the accretion onto the cluster, containing multiple groups, happens along the north-south axis and brings mostly passive galaxies, likely quenched before entering A963.
