Title: “Evidence of 200 TeV photons from HAWC J1825-134”

Abstract:
eHWC J1825-134 is one of the brightest galactic gamma-ray sources above tens of TeV in HAWC’s field of view. In recent HAWC studies a new point source, HAWC J1825-134, inside this region with spectral energy distribution (SED) extending beyond 200 TeV without any cutoff was discovered. These ultra high energy gamma-rays could be either produced by PeV electrons up-scattering the cosmic microwave background (CMB) photons through Inverse Compton scattering (IC) or by PeV cosmic rays colliding with the ambient gas. The location of this new point source is near a high density giant molecular cloud. HAWC J1825-134 is a potential candidate for a galactic cosmic-ray factory that accelerate the particles up to PeV energies.
