Description
An analysis of a ROSAT/PSPC observation of the galaxy cluster A2634 is
presented. The cluster has a luminosity of 7.9+/-0.1x10^43^erg/s in the
ROSAT band (0.1-2.4keV). The temperature profile decreases from about
3keV in the outer parts to 1.2keV in the centre. Within a radius of
1.5Mpc the gas mass of the cluster is 0.51x10^14^Msun_ and
the total mass amounts to 4.1^+2.6^_-1.8_x10^14^Msun_. The
X-ray morphology shows two peculiar features - a strongly peaked
emission in the centre and an excess emission in the south-west. The
central emission probably originates from a weak cooling flow, the SW
emission is possibly associated with higher density regions in pressure
equilibrium with the intra-cluster medium. This region of excess
emission is somewhat embraced by the wide-angle radio tails associated
with 3C465 suggesting that the overpressure of the relativistic
particles has displaced the thermal gas.
