| Abstract | We have recently discovered a massive cool core cluster at the epoch of clusterformation (z=1.709; SpARCS1049). Using deep Chandra data, we found that the coolcore is catastrophically cooling with no AGN feedback from the central galaxy.The hot intracluster gas is thus fuelling a massive burst of star formation(860+/-130 M_sun/yr), marking the first cooling flow without AGN feedback. Wepropose deep (526 ks) XMM observations to: 1) detect cooling flow spectralsignatures; 2) map for the first time metallicity in a z>1 cool core cluster; 3)explore the assembling outer halo of the intracluster gas and self-similarstatus. These observations will play a crucial role in understanding thetransition of massive structures from proto-clusters to galaxy clusters |

| 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. |
