Magnetic Pressure Dominance Stabilizes AGN Disks Against Gravitational Instability
Hannalore J. Gerling-Dunsmore, Mitchell C. Begelman, Jacob B. Simon +1
Magnetic effects have long been considered a possible factor in stabilizing the outer regions of active galactic nuclei (AGN) accretion disks against gravitational instability (GI)…

Does magnetic field promote or suppress fragmentation in AGN disks? Results from local shearing box simulations with simple cooling
Tsun Hin Navin Tsung, Mitchell C. Begelman, Philip J. Armitage +2
Accretion disks in Active Galactic Nuclei (AGN) are predicted to become gravitationally unstable substantially interior to the black hole's sphere of influence, at radii where the…
