Abstract We propose Chandra ACIS (130ks) + XMM EPIC (100ks) observations of a cluster atz=1.05, recently detected in the XMM-LSS survey, to measure the properties ofthe X-ray gas and dark matter as part of a detailed multiwavelength study. Thisis only the sixth X-ray selected cluster known at z>1. It appears to have arelaxed X-ray morphology outside the core, making it almost unique at high z.The observations wil give detailed, accurate measurements of the morphology,total mass and gas mass fraction for the first time. Uniquely we will trace thesurface brightness and tempearture structure from the core to the virial radius,to give an accurate total mass and thus a benchmark point in the cluster scalingrelations at z=1, a vital component of cosmological studies using X-ray clusters.

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.
