Abstract

GeV gamma-ray emission from two gamma-ray binaries, HESS J0631+057 and AGL J2241+4454, which were recently reported by H.E.S.S. and AGILE, respectively, have been searched for using Fermi-LAT archival dataset. Spatical and temporal distribution of gamma-ray events are studied and compared with properties shown in the discovery reports, and implication on their high-energy emission mechanism is discussed.
