Examining a hadronic $\gamma$-ray scenario for the radiative shell & molecular clouds of the old GeV supernova remnant G298.6$-$0.0
Based on the 13.7~yr Fermi-LAT data, Yeung et al. (2023) claimed detection of two $\gamma$-ray sources (Src-NE and Src-NW) associated with the supernova remnant (SNR) G298.6$-$0.0, and interpreted it as an old GeV SNR interacting with molecular clouds (MCs). In this follow-up study, we refine the flux measurements below 2~GeV …
