A numerical model for the γ-ray emission of the microquasar LS 5039.

BOSCH-RAMON V. and PAREDES J.M.

Abstract (from CDS):

The possible association between the microquasar LS 5039 and the EGRET source 3EG J1824-1514 suggests that microquasars could also be sources of high-energy γ-rays. In this paper, we explore, with a detailed numerical model, if this system can produce the emission detected by EGRET (>100MeV) through inverse Compton (IC) scattering. Our numerical approach considers a population of relativistic electrons entrained in a cylindrical inhomogeneous jet, interacting with both the radiation and the magnetic fields, taking into account the Thomson and Klein-Nishina regimes of interaction. The computed spectrum reproduces the observed spectral characteristics at very high energy.
