| ABSTRACT | |
| Galactic PeVatrons are a new, exciting class in high energy astrophysics, following the LHAASO discovery of 14 ultra-high-energy (UHE; > 100 TeV) sources in the Galactic disk. However, the mechanism powering the majority of UHE sources remains a mystery. Common leptonic and hadronic accelerators include PWNe, SNRs interacting with clouds, and star clusters. Surprisingly, four of the LHAASO sources have no active particle accelerator candidates in their vicinity and remain mostly undetected below the UHE band. We propose an extensive X-ray survey of these “dark” PeVatron accelerators, utilizing XMM's large FOV and spectro-imaging capability. Our program, combined with the planned VERITAS TeV observations, will collect X-ray legacy data on the most energetic and enigmatic objects in our galaxy. | |
