gammahalo
Gammahalo is a term used in astrophysics to describe a hypothetical region of high-energy gamma-ray emission surrounding certain celestial objects, particularly pulsars and active galactic nuclei. These gamma-ray halos are thought to be produced by the interaction of high-energy particles, such as electrons and positrons, with magnetic fields or surrounding matter. The precise mechanisms responsible for the acceleration and confinement of these particles within the halo are still a subject of active research.
The detection of gamma-ray halos is challenging due to the diffuse nature of the emission and the
