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.
