Efficient Generation of Jets from Magnetically Arrested Accretion on a Rapidly Spinning Black Hole
Alexander Tchekhovskoy, Ramesh Narayan, Jonathan C. McKinney
We describe global, 3D, time-dependent, non-radiative, general-relativistic, magnetohydrodynamic simulations of accreting black holes (BHs). The simulations are designed to transpo…
Resistive Solutions for Pulsar Magnetospheres
Jason Li, Anatoly Spitkovsky, Alexander Tchekhovskoy
The current state of the art in the modeling of pulsar magnetospheres invokes either the vacuum or force-free limits for the magnetospheric plasma. Neither of these limits can simu…
Constraints on Cold Magnetized Shocks in Gamma-Ray Bursts
Ramesh Narayan, Pawan Kumar, Alexander Tchekhovskoy
We consider a model in which the ultra-relativistic jet in a gamma-ray burst (GRB) is cold and magnetically accelerated. We assume that the energy flux in the outflowing material i…
