The Cosmic-Ray Knee as a Local Signature of Nearby PeVatrons
A “knee” in the cosmic-ray spectrum, characterized by a sudden steepening of the spectral shape at ∼4 PeV, may be interpreted either as a global feature of Galactic cosmic rays or as a local signature. In the former scenario, cosmic-ray spectra throughout the Galaxy would be similar to that observed...
