|Title||XMM-NEWTON STUDIES OF DLS SHEAR-SELECTED GALAXY CLUSTERS|
|Author||Prof JOHN P. HUGHES|
|Description||We propose to study several massive X-ray clusters identified in the Deep Lens Survey (DLS) from their weak lensing shear. The DLS is a deep multicolor (BVRz.) imaging survey of 28 square degrees being carried out at the 4-m telescopes of the US National Observatories. The DLS shear-selected cluster sample makes it possible for the first time to study clusters in a baryon-independent way. We are pursuing detailed investigations of this sample with HST and ground-based Keck spectroscopy. The main goal of these XMM-Newton observations is to measure the intracluster gas temperatures of confirmed X-ray clusters in the DLS.|

|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.
