| Abstract | We propose a deep 100 ks observation of XLSSU J021744.1-034536, a galaxy clusterdiscovered by the XMM-LSS survey. The cluster was confirmed through optical andNIR imaging, and has 10-band photometric data indicating the very high redshiftof z=1.9. We obtained a high-significance detection of the Sunyaev-Zeldovicheffect of this system, confirming the presence of hot gas and providing anestimate of the cluster mass (1-2 10^14 Msun). The proposed observations willallow us to measure key properties of the intracluster medium, namely the gasmass, temperature and center-excised luminosity. The data will provide an anchorfor extending our understanding of cluster growth and scaling relations to highredshifts, and will enhance the cosmological power of the XMM-XXL survey. |

| 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. |
