MACSJ1206 is a very massive hot cluster which is part of the CLASH sample. Ourhigh resolution MUSTANG SZ image shows an excess NE of the cluster core which iscoincident with a large group of galaxies seen optically and in weak lensing. Wewill detect the X-rays from this group, and determine if it is foreground orinfalling (perhaps with a shock) into MACSJ1206. GMRT radio data show anextended feature to the W of the cluster center. We will determine if this is aradio relic or displaced radio lobe. MACSJ1206 has very extensive galaxyvelocity and lensing data, and the masses agree well. We will determine theX-ray hydrostatic mass out of 1.5 Mpc; comparison to the lensing and dynamicalmasses will give the strongest constraints on hydrostatic bias in X-ray masses.

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.
