| Abstract | We propose an XMM/EPIC + Chandra observation of Cl1415.1+3612 (z=1.013), the most distant massive cluster known, to measure the properties of the X-ray gas and dark matter, as part of a detailed multi-wavelength study. ROSAT observations suggest it has a relaxed X-ray morphology, implying that the cluster is virialised, which would make it almost unique amongst distant galaxy clusters. The observations will give allow detailed, accurate measurements of the morphology, total mass and gas mass fraction of this important cluster for the first time. Uniquely, we will test for evolution in the mass-temperature relation 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. |
