Abstract (from CDS):
An analysis of a ROSAT/PSPC observation of the galaxy cluster A2634 is presented. The cluster has a luminosity of 7.9±0.1x1043erg/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 0.51x1014M☉ and the total mass amounts to 4.1+2.6–1.8x1014M☉. 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.
