Supernova Remnants: X Rays

Scientific paper

The authors have discovered in a ROSAT PSPC observation a diffuse extended object of size 30×30 arcmin2, which is in all likelihood a previously unknown Galactic supernova remnant. It is of particular interest since it appears to exhibit very low radio emission, and as most known SNRs have been discovered by their radio properties, this object may be part of a new sub-class of supernova remnant unknown before ROSAT. G 32.1-0.9 has a centre-filled X-ray morphology and displays some evidence of an X-ray shell. Its spectrum is well modelled by a thermal plasma model with a temperature of ≅0.8 keV and a chemical composition ≅0.3×solar. The intervening hydrogen column density is about a quarter of the full Galactic value.
