Abstract

We present a comparison of the X-ray properties of the supernova remnants CTB 37A (G348.5+0.1) and 3C397 (G41.1-0.3). We performed an analysis of archival Chandra observations for both of these remnants. This study has shown that these are both very different from each other. Due to the models that were used in order to fit the spectra of CTB 37A it can be said that it is at or is very close to being at ionization equilibrium. However, in contrast 3C397 cannot be fit with the same model and because of how its spectra is fit it is shown that it isn’t at ionization equilibrium. This study also demonstrates that in order to obtain an adequate fit for the spectra of different regions of 3C397 a single thermal component model will not work, but instead it is necessary to utilize two thermal components.
