Galactic Superaccreting X-Ray Binaries as Super-PeVatron Accelerators

The extension of the cosmic-ray (CR) spectrum well beyond 1 PeV necessitates the existence of a population of accelerators in the Milky Way, which we refer to as super-PeVatrons. Identifying the nature of these sources remains a challenge to the paradigm of Galactic CRs. Galactic superaccreting X-ra...
