HAWC J2227+ 610 and its association with G106. 3+ 2.7, a new potential Galactic PeVatron
Abstract:
We present the detection of very-high-energy gamma-ray emission above 100 TeV from HAWC J2227+ 610 with the High-Altitude Water Cherenov Gamma-Ray Observatory (HAWC) observatory. Combining our observations with previously published results by the Very Energetic Radiation Imaging Telescope Array System (VERTIAS), we interpret the gamma-ray emission from HAWC J2227+ 610 as emission from protons with a lower limit in their cutoff energy of 800 TeV. The most likely source of the protons is the associated supernova remnant G106. 3+ 2.7, making it a good candidate for a Galactic PeVatron. However, a purely leptonic origin of the observed emission cannot be excluded at this time.
