Probing the nature of Galactic microquasars with diffuse gamma rays and neutrinos: low-mass versus high-mass X-ray binaries

The observations of sub-PeV gamma-ray emission have provided strong evidence for a Galactic origin of the cosmic-ray"knee"region. Meanwhile, mounting observations have ruled out most supernova remnants as sources of PeV cosmic rays, i.e., the so-called PeVatrons. Recently, a new type of PeVatron candidate, microquasars...
