Abstract So far, the cooling flow scenario has attained a wide consensus, and extensivelyinvoked to interpret the phenomena observed from XD type clusters. However,serious doubt on the reality of massive cooling flows was cast by a series of new discoveries obtained from ASCA observations of central regions of XD cluster, which are two-temperature nature, central potential dimple, and metallicity concentration. The Centaurus cluster, which is the second closest (z=0.0104) XD cluster, most clearly represents these new findings and is the best target for a further observational examination of the cooling flow hypothesis. With the fine spatial resolution in wide energy band and large effective area, XMM will definitely achieve a novel step in this research field.

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.
