How quasars with thick accretion disk eject relativistic jets

Netsivi Ben-Amots


One of the unsolved problems in physics is how thick accretion disks produce and eject relativistic jets. "Jet-producing disks are thick". Another unsolved problem is how quasars and active galactic nuclei persist at least millions of years, while their masses are up to milliards of solar masses. Here we suggest that these problems are connected and solved simultaneously by a series of processes not recognized until now, some of them involving relativistic effects. The thick toroidal accretion disk around a massive central body is derived analytically by Newtonian conservation of angular momentum. Radiation emitted from the accretion disk enhances the particles of the jets to relativistic velocity. The particles are expelled as jets from the poles of the rotating central body, whose mass is millions to trillions of sun masses. The central body possesses radius, as predicted by exponential gravitation and proved by the discovery of gravitational waves from colliding massive bodies. The source of energy at the center of the massive central body is explained, as well as the formation of the inner jets and how they expel from the poles. Various implications are discussed.


Netsivi Ben-Amots was born in Tel-Aviv in 1941. He is a graduate of the Technion - Israel Institute for Technology, Haifa, Israel, where he got his B.Sc. in Mechanical engineering in 1963, M.Sc. in Mechanics in 1969 (thesis subject - The dynamical behaviour of a rotor on a belt suspension drive), and D.Sc. in Mechanics in 1976 (thesis subject - The motion of a high-speed rotor under the influence of a moment perpendicular to the axes of precession and nutation). Dr. Ben-Amots was invited in 1990 to the Faculty of Physics in the Technion by Professor Nathan Rosen (A student and co-author of Albert Einstein and the founder of the Faculties of Physics at the Technion, Haifa, and Ben-Gurion University in Beer-Sheva). Dr. Ben-Amots was a guest of the Faculty of Physics at the Technion for two years, in which he learned relativity and astrophysics. Dr. Ben-Amots lives in Haifa, Israel. He is a member of the standing committee of IARD - International Association for Relativistic Dynamics from the year 2000. Dr. Ben-Amots's professional activities included mechanical engineering and software development. His expertise includes dynamics, rotations, computerized simulation, and computer programming.
