|Title||Origin of the SZ and Radio Structures in the Massive CLASH Cluster MACS J1206|
|Author||Prof Craig Sarazin|
|Description||MACSJ1206 is a very massive hot cluster which is part of the CLASH sample. Our high resolution MUSTANG SZ image shows an excess NE of the cluster core which is coincident with a large group of galaxies seen optically and in weak lensing. We will detect the X-rays from this group, and determine if it is foreground or infalling (perhaps with a shock) into MACSJ1206. GMRT radio data show an extended feature to the W of the cluster center. We will determine if this is a radio relic or displaced radio lobe. MACSJ1206 has very extensive galaxy velocity and lensing data, and the masses agree well. We will determine the X-ray hydrostatic mass out of 1.5 Mpc; comparison to the lensing and dynamical masses will give the strongest constraints on hydrostatic bias in X-ray masses.|

|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.
