G156.2+5.7 is an X-ray bright, large supernova remnant with evidence fornonthermal X-ray emission from its rims, suggesting the presence of efficientshock acceleration of relativistic particles. It has been recently shown to havean extensive set of Balmer line optical emission that can be used to obtainmeasurements of the post-shock proton temperature. This proposal aims to obtainEPIC pointings toward each of three separate portions of the rim in order tomeasure the post-shock electron temperature from the thermal emission at theshock. We will also investigate the morphology and spectral characteristics ofthe nonthermal X-ray emission.

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.
