Exploring the Diffuse X-ray Emission of Supernova Remnant Kesteven 69 with XMM-Newton

We have investigated the X-ray emission from the shock-heated plasma of the Galactic supernova remnant Kesteven 69 withXMM-Newton. Assuming the plasma is at collisional ionization equilibrium, a plasma temperature and a column absorptionare found to be kT ~ 0.62 keV and NH ~ 2.85 ×1022 cm-2 respecti...

Zusammenfassung:We have investigated the X-ray emission from the shock-heated plasma of the Galactic supernova remnant Kesteven 69 withXMM-Newton. Assuming the plasma is at collisional ionization equilibrium, a plasma temperature and a column absorptionare found to be kT ~ 0.62 keV and NH ~ 2.85 ×1022 cm-2 respectively by imaging spectroscopy. Together with the deducedemission measure, we place constraints on its Sedov parameters.
