| Description | We propose deep EPIC observations of two X-ray selected spectroscopically confirmed, clusters at z=1.10 and z=1.23. High S/N X-ray imaging and spectroscopy will allow us to measure, for the first time, both the temperature and the metallicity of the intra-cluster gas in two bona-fide clusters at z>1, with unprecented insight in their physical properties. Given the large look-back time, these measurements: 1. will yield an estimate of the cluster masses with direct implications on cosmological models; 2. will permit to study evolutionary effects on the cluster Lx-T relation; 3. will also constrain the mode and epoch of metal enrichment of the gas. |

| 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. |
