We present CHANDRA X-ray and NTT optical observations of the distant z= 0:52 galaxy cluster RBS 380 - the most distant cluster of the ROSAT Bright Source (RBS) catalogue. We find diuse, non-spherically symmetric X-ray emission with a X-ray luminosity of LX(0:3 10 keV) = 1:6 10 44 erg/s, which is lower than expected from the RBS. The reason is a bright AGN in the centre of the cluster contributing considerably to the X-ray flux. This AGN could not be resolved with ROSAT. In optical wavelength we…

Discovery of depressions in the X-ray emission of the distant galaxy cluster RBS797 in a CHANDRA observation
We present CHANDRA observations of the X-ray luminous, distant galaxy cluster RBS797 at z = 0.35. In the central region the X-ray emission shows two pronounced X-ray minima, which are located
