英文摘要: We report the detection of GeV gamma-ray emission from supernova remnant HESS J1731-347 using 9 yr of Fermi Large Area Telescope data. We find a slightly extended GeV source in the direction of HESS J1731-347. The spectrum above 1 GeV can be fitted by a power law with an index of Gamma = 1.77 +/- 0.14, and the GeV spectrum connects smoothly with the TeV spectrum of HESS J1731-347. Either a hadronic-leptonic or a pure leptonic model can fit the multiwavelength spectral energy distribution of the source. However, the hard GeV gamma-ray spectrum is more naturally produced in a leptonic (inverse Compton scattering) scenario, under the framework of diffusive shock acceleration. We also searched for the GeV gamma-ray emission from the nearby TeV source HESS J1729-345. No significant GeV gamma-ray emission is found, and upper limits are derived.
