The three systems known today have hard X-ray spectra (photon index ~ 1.5), extended radio emission and a high luminosity in gamma-rays. Recent monitoring campaigns of LSI +61 303 in X-rays have confirmed variability in these systems and revealed a spectral hardening with increasing flux. In a generic one-zone leptonic model, the cooling of relativistic electrons accounts for the main spectral and temporal features observed at high energy. Persistent hard X-ray emission is expected to extend well beyond 10 keV. We explain how Simbol-X will constrain the existing models in connection with Fermi Space Telescope measurements. Because of its unprecedented sensitivity in hard X-rays, Simbol-X will also play a role in the discovery of new gamma-ray binaries, giving new insights into the evolution of compact binaries.", "revisions": [ { "version": "v1", "updated": "2009-02-18T13:19:22.000Z" } ], "analyses": { "subjects": [ "98.35.Jk", "95.85.Nv", "95.55.Ka", "95.75.Fg", "98.70.Qy" ], "keywords": [ "gamma-ray binaries", "generic one-zone leptonic model", "fermi space telescope measurements", "persistent hard x-ray emission", "hard x-ray spectra" ], "tags": [ "journal article" ], "publication": { "publisher": "AIP", "journal": "AIP Conf.
