Lepto-hadronic models of high-energy radiation from microquasars: application to GX 339-4

Abstract

In this work we apply a jet model to explain the observed broadband spectrum of GX 339-4 in the low-hard state, and make predictions for the emission in the gamma-ray domain. In our model, the electromagnetic emission is produced through the interaction of relativistic protons and electrons in the jet with local matter, radiation and magnetic fields. We expect to compare our predictions with the observations to be carried in the near future by instruments like the Fermi satellite andground-based Cherenkov telescope arrays, in the GeV and TeV energy ranges, respectively.
