| Description | We propose deep XMM observations (totalling 234ks) of three z>0.75 galaxy clusters to measure temperature profiles and hence precise hydrostatic masses, completing a sample of six. This sample will constrain the normalisation of the Yx-M scaling relation to 10% at z=0.9, and its evolution parameter to 12%. The Sunyaev-Zel dovich effect mass estimators will also be calibrated with a similar precision (a first at these redshifts). We will also measure precise gas fractions (leading to improved cosmological constraints), and study the evolution of the metal abundance of the intra-cluster medium. |

| 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. |
