Astrophysics and Space Science, 2007 Recent observations have shown that some compact stellar binaries radiate the highest energy light in the universe. The challenge has been to determine the nature of the compact object and whether the very high energy gamma-rays are ultimately powered by pulsar winds or relativistic jets.openaire +3 more sourcesA gamma-ray determination of the Universe’s star formation history [PDF]

International Journal of Modern Physics: Conference Series, 2014 Gamma-ray binaries are binary systems that emit most of their radiative output above 1 MeV. Following the detection of five such systems in the past decade, they have been clearly established as a population of galactic GeV and TeV sources.
