The SZ-selected cluster SPT-CLJ2344-4243 at zvirgul0.56 (the Phoenix cluster) showsfor the first time a hint of a massive cooling-flow-induced starburst,suggesting that the feedback source responsible for preventing runaway coolingmay not yet be fully established. We propose to robustly estimate the emissionmeasure distribution of the cool core in the Phoenix cluster, and itstemperature and abundance profiles out to 500 kpc, with a medium-deep (210 ks)EPIC observation, in order to investigate the actual structure of the cool core.The proposed study will provide secure science results with a relatively modestexposure, paving the way to an eventual deeper observation of this exceptionaland puzzling source.

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.
