There are 274 supernova remnants (SNRs) have been identified in the Milky Way.Most SNRs are discovered in radio surveys. In view of various selection effects,the current sample of SNRs is clearly incomplete. ROSAT all-sky survey data haveprovided another window to search for SNRs. We have chosen some bright andpromising SNR candidates as the starting point of a long-term identificationcampaign. We propose a set of short XMM-Newton observations to have a fullcoverage of these targets in order to investigate their spectra and morphologiesin details as well as to search for the associated compact stellar remnantsproduced in the supernova explosions.

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.
