Description Recent observations revealed that several shell-like supernova remnants (SNRs) exhibit power-law spectra with no emission line which is considered to be synchrotron radiation from high energy electrons (> 1 TeV) accelerated by the Fermi process in the SNR shell. G156.2+5.7 is an old SNR (age ~10E4 year), but emit hard X-rays in addition to usual thin thermal emission (~0.5 keV temperature). We propose to separately observe the thermal plasma and the hard X-ray tail component. Our primary objective is to determine whether or not the hard X-ray tail is synchrotron X-rays, and study the cosmic ray acceleration in this old SNR.

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.
