摘要: With the advent of Fermi Large Area Telescope (Fermi hereafter), total number gamma-ray sources has almost reached 2000 and continues at a rapid pace. The second catalog was released in 2012 contained 1873 sources, with only 127 those firmly identified. The large unidentified means that interesting physics could be discovered. This thesis will present study emission from X-ray radio binary systems using satellite. A review binaries is presented examples detected by Fermi. Gamma-ray mechanisms are discussed particular focus on likely to systems. connection between X-ray, emphasis features can searched observations. A telescopes leading up satellite followed detailed discussion event reconstruction, classification background rejection. detecter point spread function, energy dispersion effective area shown an overview recommended data analysis threads used throughout thesis. The current status have already been observed potentially other discussed. techniques this including temporal, statistical, cross correlation pulsar gating are presented. The results known Cygnus X-3 PSR B1259-63 along side possible detection Circinus X-1. 4.8 hour orbital period clearly after application technique. simultaneously for first time GeV during its periastron passage. flare also 15 days which not radio, TeV. Two catalogues containing analysed presented. Three found interest further as potential candidates. Although no definitive detections were obtained, upper limits flux provide good starting point future observations detectors.
