Trapping of magnetic flux by the plunge region of a black hole accretion disk
Christopher S. Reynolds, David Garofalo, Mitchell C. Begelman
The existence of the radius of marginal stability means that accretion flows around black holes invariably undergo a transition from a MHD turbulent disk-like flow to an inward plu…
Sporadically Torqued Accretion Disks Around Black Holes
David Garofalo, Christopher S. Reynolds
The assumption that black hole accretion disks possess an untorqued inner boundary, the so-called zero torque boundary condition, has been employed by models of black hole disks fo…
Black Hole Spin in AGN and GBHCs
Christopher S. Reynolds, Laura W. Brenneman, David Garofalo
We discuss constraints on black hole spin and spin-related astrophysics as derived from X-ray spectroscopy. After a brief discussion about the robustness with which X-ray spectrosc…
