Possible Origin of a Newly Discovered GeV Gamma-Ray Source Fermi J1242.5+3236

Based on the first 13.4 yr of Fermi science data in the energy range from 300 MeV to 500 GeV, we discovered a bright GeV gamma-ray source with a ∼5.64 σ detection, named Fermi J1242.5+3236, which has an offset of about 0.°0996 from a nearby star-forming galaxy NGC 4631. When using the 12 yr’ data, t...
