Alignment of Magnetized Accretion Disks and Relativistic Jets with Spinning Black Holes
Jonathan C. McKinney, Alexander Tchekhovskoy, Roger D. Blandford
Accreting black holes (BHs) produce intense radiation and powerful relativistic jets, which are affected by the BH's spin magnitude and direction. While thin disks might align with…
Time-Dependent 3D Magnetohydrodynamic Pulsar Magnetospheres: Oblique Rotators
Alexander Tchekhovskoy, Anatoly Spitkovsky, Jason G. Li
The current state of the art in pulsar magnetosphere modeling assumes the force-free limit of magnetospheric plasma. This limit retains only partial information about plasma veloci…
General Relativistic Modeling of Magnetized Jets from Accreting Black Holes
Alexander Tchekhovskoy, Jonathan C. McKinney, Ramesh Narayan
Recent advances in general relativistic magnetohydrodynamic modeling of jets offer unprecedented insights into the inner workings of accreting black holes that power the jets in ac…
On the Spin-Down of Intermittent Pulsars
Jason Li, Anatoly Spitkovsky, Alexander Tchekhovskoy
Magnetospheres of pulsars are thought to be filled with plasma, and variations in plasma supply can affect both pulsar emission properties and spin-down rates. A number of recently…
Prograde and Retrograde Black Holes: Whose Jet is More Powerful?
Alexander Tchekhovskoy, Jonathan C. McKinney
The outflow efficiency (eta) from black hole (BH) accretion disc systems is known to depend upon both the BH spin (a) and the amount of large-scale magnetic flux threading the BH a…
General Relativistic Magnetohydrodynamic Simulations of Magnetically Choked Accretion Flows around Black Holes
Jonathan C. McKinney, Alexander Tchekhovskoy, Roger D. Blandford
Black hole (BH) accretion flows and jets are qualitatively affected by the presence of ordered magnetic fields. We study fully three-dimensional global general relativistic magneto…
