摘要

During a search for gamma-ray emission from NGC?3628 (Arp 317), two new unidentified gamma-ray sources were discovered, Fermi J1049.7+0435 and J1103.2+1145. The detections were made using data from the Large Area Telescope (LAT), on board the Fermi Gamma-Ray Space Telescope, in the 100?MeV to 300?GeV band during the period between 2008 August 5 and 2012 October 27. Neither detection is coincident with any source listed in the second Fermi-LAT (2FGL) catalog. Fermi J1049.7+0435 is at Galactic coordinates (l, b) = (24534, 5327), (αJ2000, δJ2000) = (16243, 460). Fermi J1103.2+1145 is at Galactic coordinates (l, b) = (23885, 6033), (αJ2000, δJ2000) = (16581, 1175). Possible radio counterparts are found for both sources, which show flat radio spectra similar to other Fermi-LAT detected active galactic nuclei, and their identifications are discussed.
