Abstract A key to understanding cluster evolution is to study distant clusters ofgalaxiesin X-rays. We propose to observe with Chandra, XMM-Newton, and Spitzer CL1257(Cl J1257+4738). CL1257 is the most distant (z=0.866) cluster found in the SHARCsurvey and the second most X-ray luminous cluster above z=0.85. The data willhelp to determine the global physical properties of CL1257 and its globaldynamical state. With recent Gemini data we found 4 out of 6 cluster membergalaxies to have OII 3727 emission lines, implying recent starburst activity.A compilation of luminosity versus redshift of known clusters above z=0.85suggests that clusters do not reach their peak X-ray luminosity until z=0.9.

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.
