A rare case of FR I interaction with a hot X-ray bridge in the A2384
  galaxy cluster
  Clusters of varying mass ratios can merge and the process significantly
disturbs the cluster environments and alters their global properties. Active
radio galaxies are another phenomenon that can also affect cluster
environments. Radio jets can interact with the intra-cluster medium (ICM) and
locally affect its properties. Abell~2384 (hereafter A2384) is a unique system
that has a dense, hot X-ray filament or bridge connecting the two unequal mass
clusters A2384(N) and A2384(S). The analysis of its morphology suggests that
A2384 is a post-merger system where A2384(S) has already interacted with the
A2384(N), and as a result hot gas has been stripped over a ~ 1 Mpc region
between the two bodies. We have obtained its 325 MHz GMRT data, and we detected
a peculiar FR I type radio galaxy which is a part of the A2384(S). One of its
radio lobes interacts with the hot X-ray bridge and pushes the hot gas in the
opposite direction. This results in displacement in the bridge close to
A2384(S). Based on Chandra and XMM-Newton X-ray observations, we notice a
temperature and entropy enhancement at the radio lobe-X-ray plasma interaction
site, which further suggests that the radio lobe is changing thermal plasma
properties. We have also studied the radio properties of the FR I radio galaxy,
and found that the size and radio luminosity of the interacting north lobe of
the FR I galaxy are lower than those of the accompanying south lobe.
