LHAASO gamma-ray data from G150.3+4.5 and γ-Cygni show high-energy components produced by PeV cosmic rays from supernova remnants colliding with molecular clouds.
Wolf-Rayet star clusters show a marginal spatial correlation with unidentified GeV gamma-ray sources, with 11 new cluster associations and 4 isolated WR stars identified as potential emitters from wind termination shocks.
The GeV emission zone in Cygnus X-3 is too large and magnetized too weakly to accelerate protons to PeV energies, so the PeV gamma rays must originate from a more compact inner region with rapid magnetic field dissipation.
Reviews IceCube neutrino results, models Galactic plane flux from cosmic ray interactions with the interstellar medium, and discusses prospects for identifying PeVatrons via LHAASO sources.
