|Title||Cluster Lensing and the Impact of Cooling Flows|
|Author||Dr Steven Allen|
|Description||We propose to observe three well-studied cluster gravitational lenses, which are amongst the most X-ray luminous and massive systems known at intermediate redshifts. The observations will permit accurate determinations of the X-ray gas mass, total mass, baryon and metallicity distributions in the clusters. The data will reveal the impact of cooling flows on X-ray mass measurements and elucidate the origins of the discrepancies between X-ray and strong lensing masses for clusters without cooling flows. The data will also provide a crucial step in establishing the mass-temperature relation for luminous 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.
