Scientific paper

RXCJ1504.1-0248 discovered at z=0.2153 in the REFLEX survey is the most X-ray luminous known cluster in the southern sky below z=0.4. A 13ks CHANDRA snap-shot reveals a global kT=10keV, 5.5keV at the center, but no lower temperatures and no increase of Fe abundance towards the center. The formal mass deposition rate is the 2nd highest found sofar. With a deeper exposure we can obtain a detailed temperature-profile, test the central region for a multi-phase temperature structure to check for disturbances by interaction effects, the morphology of the central region to check indications of asymmetry, to use the Fe abundance distribution to learn more about the enrichment age of the cooling core, and to test how far Fe enrichment of the central galaxy gas been transported outwards.
