|Title||Probing shock modification in G156.2+5.7|
|Author||Dr Marco Miceli|
|Description||We propose a 50 ks EPIC observation of the northern limb of the galactic supernova remnant G156.2+5.7. The X-ray spectrum of this remnant is dominated by thermal emission, but also shows a non-thermal component that indicates efficient particle acceleration at the shock front. The proposed observation is aimed at probing the effects of particle acceleration on the thermal properties of the post-shock plasma. G156.2+5.7 is a perfect candidate for these studies, being the only remnant with efficient particle acceleration where thermal emission from the post-shock medium has been firmly detected. The new observation will allow us to constrain the effects of particle acceleration on the post-shock temperature and density, thus providing a benchmark for the shock modification theories.|

|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.
