Supernova connection of unidentified ultra-high-energy gamma-ray source LHAASO J2108+5157
ABSTRACT We present a simple phenomenological model of hadronic interaction between protons accelerated in an old supernova remnant (SNR) and cold protons situated within the associated molecular clouds (MCs). The accelerated protons from the old SNR escaped the SNR shock front, and got injected into the MCs at an earlier …
