| Abstract | SN 1006 was shown by ASCA to be of a dual nature, with non-thermal emissioncoming from the bright limbs and fainter thermal emission coming from the centerand the other sides. This is the best example we have of shock accelerationof cosmic-ray electrons to energies approaching the knee in the cosmic-rayspectrum (supernova remnants are thought to be the main sites of cosmic-rayacceleration). We have analysed our first 7 ks XMM-Newton pointing on SN 1006North East, and have measured for the first time the radial and azimuthalvariations of the synchrotron emission. We propose to map the whole remnant withdeeper exposures, allowing spectral analysis at a scale of 15 arcsec (about theXMM HEW) in the bright limbs and at a scale of 1 arcmin in the interior. |

| 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. |
