Compact gamma-ray binaries
In the recent years a new window on the universe has been opened by ground based and space telescopes that survey the sky by detecting high energy photons, which have energies from a few, up to hundreds of gig electron volts (GeV). Because of the poor angular resolution of the gamma-ray telescopes r...
