Gamma-Rays from rotating black holesAbstract The gamma-ray luminosity due to the decay of pions produced during spherical accretion onto rotating black holes has been calculated. The model consists of a Kerr black hole of arbitrary angular momentum surrounded by interstellar gas consisting of completely ionized hydrogen atoms. There is an 80% increase in flux as we go from Schwarzschild to the extreme Kerr case. Paper published in The Astrophysical Journal, 280:848-852, 1984 May 15 Leave a Reply |
