Shocking Features in the Merging Galaxy Cluster RXJ0334.2-0111
  We present a 66 ksec $\textit{Chandra}$ X-ray observation of the galaxy
cluster RXJ0334.2-0111. This deep observation revealed a unique bow shock
system associated with a wide angle tail (WAT) radio galaxy and several
intriguing substructures. The temperature across the bow shock jumps by a
factor of $\sim$ 1.5 (from 4.1 keV to 6.2 keV), and is consistent with the Mach
number $M = 1.6_{-0.3}^{+0.5}$. A second inner surface brightness edge is a
cold front that marks the border between infalling subcluster cool core and the
ICM of the main cluster. The temperature across the cold front increases from
$1.3_{-0.8}^{+0.3}$ keV to $6.2_{-0.6}^{+0.6}$ keV. We find an overpressurized
region $\sim$ 250 kpc east of the cold front that is named "the eastern
extension (EE)". The EE may be a part of the third subcluster in the ongoing
merger. We also find a tail shaped feature that originates near the bow shock
and may extend up to a distance of $\sim$ 1 Mpc. This feature is also likely
overpressurized. The luminous FR-I radio galaxy, 3C89, appears to be the cD
galaxy of the infalling subcluster. We estimated 3C89's jet power from jet
bending and the possible interaction between the X-ray gas and the radio lobes.
A comparison between the shock stand-off distance and the Mach number for all
known shock front/cold front combinations suggests that the core is
continuously shrinking in size by stripping.
