Multi-wavelength Observations of Cygnus X-3

Cygnus X-3 is a X-ray binary system containing a stellar-mass black hole and a Wolf-Rayet companion star with prominent jets, placing it in the sub-category of microquasars. Due to their similarities with AGN and GRBs, they are thought to be possible gamma-ray emitters, as the recent Fermi LAT detection has proven. We have carried out VERITAS observations on this source to find a link between the hard X-ray, GeV gamma-ray and TeV gamma-ray emissions. These observations have been triggered on the recent AGILE and Swift ATels, respectively ATel #3386 and ATel #3439. This result aims to shed light on the mechanisms of particle acceleration and gamma-ray emission in microquasars within the high-energy multi-wavelength context.
