Abstract We propose deep XMM observations (totalling 234ks) of three z>0.75 galaxyclusters to measure temperature profiles and hence precise hydrostatic masses,completing a sample of six. This sample will constrain the normalisation of theYx-M scaling relation to 10% at z=0.9, and its evolution parameter to 12%. TheSunyaev-Zel dovich effect mass estimators will also be calibrated with a similarprecision (a first at these redshifts). We will also measure precise gasfractions (leading to improved cosmological constraints), and study theevolution of the metal abundance of the intra-cluster medium.

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.
