|Title||SN 1006 and cosmic-ray acceleration|
|Author||Dr Jean BALLET|
|Description||SN 1006 was shown by ASCA to be of a dual nature, with non-thermal emission coming from the bright limbs and fainter thermal emission coming from the center and the other sides. This is the best example we have of shock acceleration of cosmic-ray electrons to energies approaching the "knee" in the cosmic-ray spectrum (supernova remnants are thought to be the main sites of cosmic-ray acceleration). We have analysed our first 7 ks XMM-Newton pointing on SN 1006 North East, and have measured for the first time the radial and azimuthal variations of the synchrotron emission. We propose to map the whole remnant with deeper exposures, allowing spectral analysis at a scale of 15 arcsec (about the XMM HEW) in the bright limbs and at a scale of 1 arcmin in the interior.|

|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.
