Abstract The mass-temperature relation is crucial for understanding cluster evolution andfor precision cosmology using clusters of galaxies. To determine its slope,normalization, and intrinsic scatter, we propose to measure the temperature ofsystems in the Canadian Cluster Comparison Project. The CCCP is a CFHTwide-field weak lensing survey of 52 clusters, of which 7 have no Chandra orXMM-Newton data. With an average statistical uncertainty of 15% in mass, theCCCP surpasses the previous work in both sample size and precision. Bydetermining the mass independently of the X-ray data, we avoid assumptions suchas spherical symmetry or hydrostatic equilibrium. We will determine thenormalization of the relation to 10%, and achieve the first measurement of its intrinsic scatter.

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.
