Abstract
We present CHANDRA X-ray observations of the hot (T = 7.7^(+1.2)_( −1.0), distant (z = 0.354) gakaxy cluster RBS797. The most striking features are two spectacular minima in the X-ray emission in the core of the cluster; this suggests an interaction of radio lobes with the intracluster gas. This is the first time such depressions have been observed in a distant cluster.
