Gamma-ray Spectral and Morphological study of HESS J1912+101 observed by MAGIC and Fermi-LAT
July 22, 2019
The shock waves of supernova remnants (SNRs) are prime candidates for cosmic-ray accelerators.A general feature of the blast wave is an extended shell visible in GeV and TeV gamma rays.HESS J1912+101 is a bright unassociated extended TeV source with a shell-like structure. Thissource has no counterparts at other wavelengths so far, hence it is still labeled as ‘SNR candidate’.We are going to present the results of a deep observation campaign with the MAGIC telescopestogether with 10 years of PASS 8Fermi-LAT data. In order to analyze the data, we use a new2D likelihood software calledSkyPrismthat allows parametrization of the morphology measuredby MAGIC. We measure a joint Fermi-MAGIC flux spectrum covering three decades of energy.This spectrum is well fitted by a power-law with a hard spectral index and a cut-off at a coupleTeV.
