| Abstract | We have embarked on an extensive optical/NIR/X-ray imaging program to unveil allof the most massive clusters in the observable Universe by identifying clustercandidates selected via the Sunyaev-Zeldovich (SZ) effect by the Plancksatellite. Here we propose to observe the 17 highest signal-to-noise unconfirmedcandidates using short (10 ks) XMM-Newton exposures in order to determine eachclusters position, extent, and X-ray flux. Combining the X-ray results with ourexisting groundbased optical/NIR data will allow determination of photometricredshifts, optical richness, X-ray luminosities and, from these quantites,estimates of the cluster mass. |

| 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. |
