TL;DR: For the first time, the long-awaited detection of diffuse gamma rays with energies between 100 TeV and 1 PeV in the Galactic disk was reported in this paper, which is consistent with expectations from the hadronic emission scenario in which gamma rays originate from the decay of π 0's produced through the interaction of protons with the interstellar medium.
