Abstract

During my thesis, I studied three of the best microquasar candidates to emit at VHE: Cygnus X-1, Cygnus X-3 and V404 Cygni. For the first time, we firmly detected Cygnus X-1 in the HE regime owing to the analysis of the 7.5 years of pass 8 textitFermi data. This analysis allowed us to determine that HE gamma-ray emission only occurs during the HS and most likely associated to the relativistic jets. In turn, we found a hint of orbital modulation, which could constrain the gamma-ray emission site between \(10^{11}\)\(10^{13}\) cm from the BH produced by anisotropic IC on the stellar photon field.
