Morphology Study for GeV Emission of the Nearby Supernova Remnant G332.5-5.6
Spatial template is important to study the nearby supernova remnant (SNR). For SNR G332.5-5.6, we report a gaussian disk with radius of about 1.06 degrees to be a potential good spatial model in the gamma-ray band. Employing this new gaussian disk, its GeV lightcurve shows a significant variability of about seven sigma. The gamma-ray observations and the radio observations of this SNR could be explained well either by a leptonic model or a hadronic model, in which a flat spectrum for the ejected electrons/protons is required as well as a typical magnetic flux density at several Gaussians.
