Description S 147 is one of the most spectacular supernova remnants in the optical, and is believed to be in the radiative phase. It was recently reported as a relatively bright gamma-ray source by Fermi. In order to interpret the gamma-ray emission correctly, it is important to know whether the accelerated particles are fresh, or the relic from the times when S 147 was younger. The amount and spectrum of the relic particles depend on the past history of the density and shock velocity. The hot gas still trapped inside the remnant stands witness to that. Building on a marginal detection in the ROSAT survey, we propose an XMM-Newton observation to determine the temperature and density inside S 147.

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.
