Revealing the Gamma-Ray Jet in a Black Hole Binary

摘要

An important advance in high-energy astrophysics over the past decade has been the detailed understanding of the nature of binary stellar systems in which material from an ordinary star is being accreted on to a compact object, either a neutron star or a black hole (7,2). These systems are called x-ray binaries because emission from the accretion disk and associated material appears very bright in the x-ray regime.
