Radio to TeV radiation initiated by termination of hadronic jets from microquasars in the ISM

Abstract

Microquasars (MQs) are potential candidates to produce a non-negligible fraction of the observed galactic cosmic rays. The protons accelerated at the jet termination shock interact with the interstellar medium and may produce extended emission detectable at different energy bands through several processes: neutral pion-decay produce high-energy and very high-energy gamma-rays, secondary electrons produced by charged pion-decay generate synchrotron and bremsstrahlung emission. In addition, the jets of MQs themselves are likely sources of gamma-rays. We discuss about the association between the intrinsic and the indirect emission coming from these objects.
