| Abstract | We request XMM time to observe a new sample of the most massive galaxy clustersat z > 0.9 to determine their masses and suitability for use in f_gasmeasurements. Combining WISE with SDSS, we have constructed a catalog ofclusters in the 10,000 deg^2 overlap area, which is the first phase in a projectto find the most massive clusters over the whole sky at z > 0.9. To date, 15 newclusters at 0.9 < z < 1.3 have been spectroscopically confirmed. Moreover,nearly all of the new candidates observed by CARMA have Sunyaev-Zeldovichdetections, including one which is among the most massive clusters known at z >1. |

| 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. |
