IDCS J1426.5+3508 is arguably the most massive, very high redshift virializedcluster, with many galaxy redshifts, our strong and weak lensing data, ourstrong SZ detections, and a large X-ray flux from our Chandra observation. Wepropose a 194 ks observation to measure the global temperature and temperatureprofile, determine the metallicity, derive Y_X, find the density, pressure, andentropy profiles, and determine if this is a cool core or merging cluster. Thepressure profile will be compared to our MUSTANG2 high resolution (9.) SZimage, providing a test for clumping. The abundance will test chemical evolutionmodels for cluster galaxies given the early epoch. Even one high z, high massrelaxed cluster with an accurate mass can constrain LambdaCDM and non-gaussianity.

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.
