X-rays and Gamma Rays from Active Galactic Nuclei

  title={X-rays and Gamma Rays from Active Galactic Nuclei},
  author={R. Pugliese F. Bille A. Abrami O. Svensson},
Various types of active galactic nuclei (AGN) are briefly discussed, with an emphasis on the theory of recent X-ray and γ-ray observations of the subclass, Seyfert 1 galaxies. The large radiation power from AGN is thought to originate from gravitational power released by matter accreting onto a supermassive black hole. The physical mechanisms responsible for the energy release and the geometry of the gaseous components are still uncertain in spite of three decades of observational and… CONTINUE READING
