A Magnetic Alpha-Omega Dynamo in Active Galactic Nuclei Disks: II. Magnetic Field Generation, Theories and Simulations
Vladimir I. Pariev, Stirling A. Colgate, John M. Finn
It is shown that a dynamo can operate in an Active Galactic Nuclei accretion disk due to the Keplerian shear and due to the helical motions of expanding and twisting plumes of plas…
A Magnetic Alpha-Omega Dynamo in Active Galactic Nuclei Disks: I. The Hydrodynamics of Star-Disk Collisions and Keplerian Flow
Vladimir I. Pariev, Stirling A. Colgate
A magnetic field dynamo in the inner regions of the accretion disk surrounding the supermassive black holes in AGNs may be the mechanism for the generation of magnetic fields in ga…
Modeling the Large Scale Structures of Astrophysical Jets in the Magnetically Dominated Limit
Hui Li
We suggest a new approach that could be used for modeling both the large scale behavior of astrophysical jets and the magnetically dominated explosions in astrophysics. We describe…
Cosmological Mestel Disks and the Rossby Vortex Instability: The Origin of Supermassive Black Holes
Stirling A. Colgate, Renyue Cen, Hui Li +2
A scenario is put forth for the formation of supermassive black holes at the centers of galaxies. It depends upon the formation of a Mestel disk with a flat rotation curve, where t…
On the Particle Heating and Acceleration in Black Hole Accretion Systems
H. Li, S. A. Colgate, M. Kusunose +1
The lack of our knowledge on how angular momentum is transported in accretion disks around black holes has prevented us from fully understanding their high energy emissions. We bri…
