Energy Extraction from a Black Hole by a Strongly Magnetized Thin Accretion Disk
Prasun Dhang, Jason Dexter, Mitchell C. Begelman
The presence of a strong, large-scale magnetic field in an accretion flow leads to extraction of the rotational energy of the black hole (BH) through the Blandford-Znajek (BZ) proc…

Thermal solutions of strongly magnetized disks and the hysteresis in X-ray binaries
Nicolas Scepi, Jason Dexter, Mitchell C. Begelman +3
X-ray binaries (XRBs) exhibit spectral hysteresis for luminosities in the range , with a hard X-ray spectral state that persists from…

Shock-induced partial alignment in geometrically-thick tilted accretion disks around black holes
Sajal Gupta, Jason Dexter
We carry out idealized three-dimensional general-relativistic magnetohydrodynamic (GRMHD) simulations of prograde, weakly magnetized, and geometrically thick accretion flows where…
