Magnetic fields in the central engines of active galactic nuclei
Author and Affiliation:
Begelman, Mitchell C.(Joint Institute for Laboratory Astrophysics, Boulder, CO, United States)
Abstract: Important physical processes which may occur in the central engines of active galactic nuclei and which rely on the presence of a strong magnetic field are discussed. These processes include those involved in the plasma physics of hot tenuous accretion flows, the production of nonthermal continuum radiation, and the radiative manifestation of hydromagnetic jet production. The main arguments which support the hypothesis that supermassive black holes are the prime movers in the central engines are reviewed, and some major deduction regarding the physical state of the accreting gas are pointed out.
