We propose a 126 ks XMM-Newton observation of the Frontier Fields cluster A370,which, along with the very precise mass map derived from HST lensingobservations, and existing Chandra, Spitzer and SZ data, galaxy spectroscopy,plus hydrodynamic simulations, will allow us to understand the cluster.s mergerhistory and constrain how heavy elements as well as the thermal energy aredistributed throughout the hot cluster gas in this merging cluster. These goalsare possible to achieve since XMM-Newton offers good angular resolution, largecollecting area and excellent spectral resolution and because A370 appears to bea relatively simple merger of two similarly massive subclusters.

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.
