|Title||An X-ray - lensing calibration of cluster mass estimates|
|Author||Dr Ben Maughan|
|Description||We have compiled the largest statistically complete sample of galaxy clusters with weak lensing mass estimates. 32 of the 36 clusters have already been observed with XMM-Newton and-or Chandra. With 47ks of XMM-Newton observations, good quality X-ray data can be obtained for the remaining 4, creating a complete X-ray-lensing dataset. For the first time, X-ray and weak lensing mass estimates will be cross-calibrated in a volume limited sample. This will allow: 1) the measurement of systematic effects in cluster mass estimates and their effect on derived cosmological constraints; 2) improved calibration of the X-ray observable - mass scaling relations; and 3) accurate measurements of cluster baryon fractions.|

|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.
