The study of young supernova remnants (SNRs) is important for understanding theparticle acceleration that leads to cosmic ray production, for learning aboutsupernova explosions, and for using energetic pulsars to constrain high energyemission mechanisms. IGR J17448-3232 is a SNR candidate that would be one ofonly three SNRs that have been discovered by the INTEGRAL satellite in the hardX-ray band. The evidence that the source is a SNR comes from short Chandra andSwift exposures that show a source that is several arcminutes in size. Theevidence that it is young comes from its very hard X-ray spectrum. We proposefor an XMM-Newton observation to determine the morphology and spectralproperties of the extended emission.

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.
