|Title||XMM spectro-imagery of two young ejecta-dominated SNRs: Kepler and W49B|
|Author||Dr Anne Decourchelle|
|Description||We propose to perform an XMM observation of two young thermal supernova remnants Kepler and W49B of similar size, but with different morphologies (shell-like and center-filled). The objectives of the proposal are: - to constrain their origin (supernova type, progenitor and environment) and evolution stage by determining their distribution in abundances, in temperature and in ionization state. - to map and characterize the X-ray synchrotron emission (power law index, roll-off energy) to constrain the model of cosmic-ray acceleration in supernova remnants.|

|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.
