RX J1347-1145 is an extreme galaxy cluster discovered in the ROSAT All-Sky
Survey. Follow-up observations in optical and X-rays (with ROSAT/HRI and ASCA)
reveal a number of interesting properties. The image shows HRI contours
superposed on an NTT image, displaying a very compact cluster. In the optical
image several arcs and arc candidates are visible (marked with letters),
implying that the cluster acts as a gravitational lens.
RX J1347-1145 at z = 0.451 with a luminosity
LX(bol) = 2 x 1046 erg/s
is the most luminous X-ray cluster discovered to date. The cluster has a
strong cooling flow of more than 3000 solar masses per year, the largest
cooling flow detected so far.
