γ-ray emission from microquasars:: A numerical model for LSI+61°303

We explore the possible association between the microquasar LS1 +61degrees303 and the EGRET source 2CG 135+01/3EG J0241+6103 by studying, with a detailed numerical model, whether this system can produce the emission and the variability detected by EGRET (>100 MeV) 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. Our results reproduce the observed spectral characteristics and variability at gamma-rays, thus strengthening the identification of LS1 +61degrees303 as a high-energy gamma-ray source.
