In the REFLEX survey we recently discovered the most luminous cluster known inthe southern sky at z greater 0.35 (with z=0.21). A CHANDRA observation revealsit as one of the two most dramatic cooling core clusters. Most of the very highX-ray luminosity is actually coming from the cooling core. Both properties makethe cluster a prime study object, in particular in the light of the new coolingcore physics interpretation with a regulated feedback heating by AGN. In thispicture the amount of cooling gas that can be held by the cluster potentialagainst the dispersion by the AGN is actually regulating the amount of masscondensation and AGN Black Hole growth.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
