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...

Zusammenfassung: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 7 sigma. The \(\gamma\)-ray 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.
