Abstract We propose joint Chandra/XMM observations to measure the fundamental properties of XMMUJ2235.3-2557 (z=1.4), the most distant massive galaxy cluster known. Based on its high Lx, ICM temperature and optical/NIR richness,it is very likelythe most massive z>1 structure yet identified. The cluster provides a compellingopportunity to extend the baseline of evolutionary studies to the largest look-back time currently accesible, and yields very strong leverage for testing cluster formation scenarios and for deriving cosmological constraints. Chandra.sresolution is crucial to measure structural parameter free from point source confusion and to establish the cluster.s dymamica state. XMM.s high sensitivityis necessary to derive accurate measures of ICM temperature metallicity and mass

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.
