We propose observations of new candidates for X-ray supernova remnants (SNRs) inthe Large Magellanic Cloud (LMC). Building on a successful campaign to observecandidates with ROSAT detections in past AOs (Proposal IDs 65188, 72044, 74180,76406), we have expanded our selection criteria to include radio candidates withno X-ray detection. The proposed targets are located outside the LMC surveyperformed as a VLP in AO11. Three of the four targets are covered by ROSAT PSPCpointed observations, all located far off-axis and not identified as sources.The high sensitivity of XMM-Newton will allow us to detect SNRs that are X-rayfaint due to their age or ambient medium, complete the sample of known SNRs tolower fluxes, and obtain information about abundances, densities, and supernova energies.

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.
