| Description | We propose to follow up four distant galaxy clusters discovered by the XMM-LSS and XXL survey programs. In addition to being confirmed with optical and NIR spectroscopy or photometry, the presence of hot gas in each of these clusters has been confirmed through a significant detection of the Sunyaev-Zel dovich signal with CARMA. Three of our targets have redshifts greater than 1, with one of them at 1.5. Deeper XMM data will allow us to situate these high-redshift clusters on X-ray and SZ scaling relations and provide key mass proxies, enhancing the cosmological power of the XXL survey and enabling a variety of studies of cluster evolution. We also request joint Chandra observations in order to constrain and remove point-source contamination of the XMM signal for these faint clusters. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
