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