We report on the X-ray properties of the exceptional X-ray cluster RXJ1347.5-1145 at z=0.451. We confirm that it is with a luminosity $L_X(bol)=2\times 10^{46}$ erg/s the most luminous X-ray cluster discovered to date. The mass of the…

We present our discovery observations and analysis of RDCS1317+2911, z = 0.805, and RDCS1350+6007, z= 0.804, two clusters of galaxies identified through X-ray emission in the ROSAT Deep Cluster Survey (RDCS). We find a temperature of 3.7…
We investigate temperature and entropy profiles of 13 nearby cooling flow clusters observed with the EPIC cameras of XMM-Newton. When normalized and scaled by the virial radius the temperature profiles turn out to be remarkably similar. At…
