We present the results of ROSAT/ASCA observations of the bright southern radio source MRC 0625-536. The majority of the X-ray emission originates from the surrounding cluster Abell 3391. The best fit temperature for the cluster gas is keV with an abundance of 0.36 times the solar value. We determined the radial mass profile and extrapolating the data out to 3 Mpc, and we find that the total mass of the cluster is (0.4 - 1.6) .
Up to about 10% of the X-ray flux could originate from the central dumbbell galaxy. A comparison of the X-ray contours with the complex 13cm radio structure reveals strong interactions between the radio jets and the surrounding matter.
MRC 0625-536 is thus another object where the interaction between the otherwise invisible matter of the cluster and the activity of the central radio galaxy can be studied by combining data from the radio and the X-ray regimes.
