| Description | We propose a systematic high precision investigation of the cluster mass observable scaling relations, employing XMM data and our Subaru weak lensing data. The primary goal is to find out the best cluster mass proxy and investigate the behaviors of its scatter. Our preliminary results indicate that gas mass has lower scatter with total mass, compared to the product of gas mass and cluster temperature, Y_X. If those are confirmed, this will change the strategy for carrying out the X-ray cluster cosmology. Achieving a good control over the systematics have major implications for cluster cosmologists striving to measure the dark energy equation of state parameter, and should add a sharp multi-wavelength focus to investigations of the cluster physics. We require to observe 10 of 27 clusters (176ksec). |

| 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. |
