With ASCA observations of the Gamma Cygni SNR, we discovered two clumps which emit extremely hard X-rays. In order to obtainprecise spectral parameters and investigate the spatial structure of the hardX-ray clumps, we propose to perform spatial resolved spectroscopy with XMM-Newton observatory. We will obtain some implications for the acceleration of low energy cosmic-rays, and the mystery of the EGRET unidentified gamma-raysources.

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.
