High-Energy Gamma-Ray Emission from Galactic Kerr-Newman Black Holes. II. The Radiative Jets

A model of the unidentified high-latitude Galactic hard γ-ray (EGRET) sources based on black hole electrodynamics is presented in this paper and its companion. The γ-ray emission is produced in a bipolar outflow from a charged, rotating black hole (Kerr-Newman black hole) in a low-density region of the Galaxy. The model is a synthesis of pair creation scenarios for pulsars, the theory of black hole magnetospheres and synchrotron self-Compton (SSC) large-scale jets. In this article it is shown that the resulting emission from the SSC jet is consistent with the constraints imposed on the broadband spectral energy distribution implied by the lack of identification of the γ-ray sources in other frequency bands.
