Including in situ photoionization from embedded HII regions and shocks. the pressure exerted by the hot and dense intracluster medium (ICM) on galaxies moving at high velocity within the cluster gravitational potential well, is a key process able to remove their interstellar medium (ISM) and quench their. Among these, ram pressure stripping, i.e. Ram pressure stripping is an important process in the evolution of both dwarf galaxies and large spirals. Intriguingly, the authors also find tendril-like structures thin, long and. Identify multiple ionization mechanisms for the diffuse gas filaments, Galaxies living in rich environments are suffering different perturbations able to drastically affect their evolution. Such a pattern is expected since ram-pressure stripping mainly affects the outer parts of a galaxy’s disk. Based on the analysis of spatially-resolved emission line maps, we Global ram-pressure stripping of the intra-group material as BIG falls insideĪ1367. Previous numerical simulations based on various approaches suggested that. In the direction opposite to the cluster centre is also detected, hinting at a Ram pressure stripping of galaxies in clusters can yield gas deficient disks. Group members and the presence of tidal dwarf systems. Ram pressure stripping (RPS) is known to be a key environmental effect that can remove interstellar gas from galaxies in a cluster. This suggests that AGNfeedback may play a role in rapidly quenching galaxies duringthenal phases of RPS. The gas morphologyĪnd its kinematics appear consistent with a tidal origin due to galaxyĮncounters, as also supported by the disturbed kinematics visible in one of the Ram pressure compresses the gas and helps fuel theAGN, which imparts energy to its surroundings to helpfacilitate the stripping process. Our MUSE observations map in detail the extended ionized gas, primarily tracedīy H$\alpha$ emission, in between the members of the group. Hydrodynamic and gravitational interactions in the Blue Infalling Group, by Matteo Fossati (CEA and ICC and 10 other authors Download PDF Abstract: We report new wide-field (~ 4 x 4 square arcmin) MUSE observations of theīlue Infalling Group (BIG), a compact group of galaxies located at a projectedĭistance of ~ 150 kpc from the X-Ray centre of the A1367 cluster at z = 0.021.
