Abstract
We present ROSAT PSPC and HRI observations of the distant cluster A1300 (z = 0.3071) in conjunction with optical data, to investigate the physics of the intra-cluster medium and the dynamical state of the cluster. By means of a multi-resolution wavelet analysis, we find evidence for structures in the X-ray emission of this very luminous (LX ~ 1.7 1045 erg/s) in the 0.1--2.4 keV band) and massive (Mtot ~ 1.3 x 1015 Msun at a radius ~ 2.2 Mpc) cluster. This cluster is significant as we appear to be witnessing the end of a merger which occurred at an early epoch.
