Abstract (from CDS):

We carry out high-energy studies of the region of the Galactic TeV source 3HWC J1954+286, whose location coincides with those of PSR J1954+2836 and supernova remnant (SNR) G65.1+0.6. Analyzing the GeV γ-ray data obtained with the Large Area Telescope on board the Fermi Gamma-ray Space Telescope, we are able to separate the pulsar's emission from that of the region. Excess power-law-like emission of a ∼6σ significance level at the region is found, which we explain as arising from the SNR G65.1+0.6. Given the low-significance detection, either a hadronic or a leptonic model can provide a fit to the power-law spectrum. Considering the properties of the pulsar and the SNR, we discuss the possible origin of the TeV source, and suggest that it is likely to be the TeV halo associated with the pulsar.
