Morphology Study for GeV Emission of Nearby Supernova Remnant G332.5-5.6

A spatial template is important to study nearby supernova remnants (SNRs). For SNR G332.5-5.6, we report a Gaussian disk with a radius of about 1.°06 to be a potential good spatial model in the γ -ray band. Employing this new Gaussian disk, its GeV lightcurve shows a significant variability of about...

Zusammenfassung:	A spatial template is important to study nearby supernova remnants (SNRs). For SNR G332.5-5.6, we report a Gaussian disk with a radius of about 1.°06 to be a potential good spatial model in the γ -ray band. Employing this new Gaussian disk, its GeV lightcurve shows a significant variability of about seven sigma. The γ -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 is required.
