IGR J17448-3232: a young comma non-thermal supernova remnantquestionMark

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 J174483232 is a SNR candidate that would be one ofonly three SNRs that have been discovered by the INTEGRAL satellite in the hardXray 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 Xray spectrum. We proposefor an XMMNewton observation to determine the morphology and spectralproperties of the extended emission. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
