Isolated Black Holes as Potential PeVatrons and Ultrahigh-energy Gamma-Ray Sources
The origin of PeV cosmic rays (CRs) is a long-standing mystery, and ultrahigh-energy gamma-ray observations would play a crucial role in identifying it. Recently, LHAASO reported the discovery of “dark” gamma-ray sources that were detected above 100 TeV without any GeV–TeV gamma-ray counterparts. Th...
