Description
The Large High Altitude Air Shower Observatory (LHAASO) has ushered in a new era of ultra-high-energy (UHE, typically above 100 TeV) gamma-ray astronomy, providing unprecedented insights into the most powerful particle accelerators in the Milky Way. In this talk, I will review recent progress in the identification and characterization of Galactic PeVatron candidates, highlighting LHAASO’s detection of an expanding population of sources such as microquasars, supernova remnants, pulsar wind nebulae, and star-forming complexes, hat are capable of accelerating particles to hundreds of TeV or even PeV energies. I will also present recent measurements of Galactic diffuse gamma-ray emission by LHAASO, which provide constraints on cosmic-ray propagation and distribution in the Milky Way. These results have important implications for multimessenger astronomy, particularly in relation to high-energy neutrino observations and the origin of Galactic cosmic rays.
