Abstract

We present the detection of VHE gamma-ray emission above 100 TeV from HAWC
J2227+610 with the HAWC observatory. Combining our observations with previously
published results by VERITAS, 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.
