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 opposite to each other with respect to the cluster centre. These depressions suggest an interaction between...
