Abstract (from CDS):

We report here on the first detection at X-ray wavelengths of the Supernova Remnant (SNR) G337.8-0.1, carried out with the XMM-Newton Observatory. Using the X-ray observations, we studied the X-ray morphology of the remnant at different energy ranges, analysed the spectral properties and investigated a possible variable behavior. The SNR shows a diffuse filled-center structure in the X-ray region with an absence of a compact source in its center. We find a high column density of NH>6.9x1022cm–2, which supports a relatively distant location (d≥7kpc). The X-ray spectrum exhibits emission lines, indicating that the X-ray emission has a thin thermal plasma origin, and is well represented by a non-equilibrium ionization (NEI) plasma model. The X-ray characteristics and well-known radio parameters show that G337.8-0.1 belongs to the emerging class of mixed-morphology (MM) SNRs.
