4 Sep 2019 | | Abstract: | We report on observations of ESO156-G029, member of a galaxy group which is
positioned at the virial radius of cluster Abell 3193. ESO156-G029 is located ~
1.4 Mpc in projected distance from the brightest cluster galaxy NGC1500. We
show that ESO156-G029 has disturbed gas kinematics and a highly asymmetric
neutral hydrogen (HI) distribution, which are consequences of group
pre-processing, and possibly of ram-pressure. Based on the current data we
propose a scenario in which ESO156-G029 had a minor gas-rich merger in the past
and now starts to experience ram-pressure. We infer that the galaxy will
undergo rapid evolution once it gets closer to the cluster centre (less than
0.5 Mpc) where ram-pressure is strong enough to begin stripping the HI from the
galaxy. | | Source: | arXiv, 1909.1509 | | Services: | Forum | Review | PDF | Favorites | |
