The electric field of a charge in the vicinity of a higher dimensional black hole
David Garfinkle
We find the electric field of a point charge in the presence of a higher dimensional black hole. As the charge is lowered to the horizon, all higher multipole moments go to zero, a…
Spike behavior in the approach to spacetime singularities
David Garfinkle, Frans Pretorius
We perform numerical simulations of the approach to spacetime singularities. The simulations are done with sufficient resolution to resolve the small scale features (known as spike…
Cosmological initial data for numerical relativity
David Garfinkle, Lawrence Mead
We find initial data for numerical relativity simulations of inhomogeneous cosmologies. This involves treating an exceptional case of the general relativity constraint equations. W…
Consistent Blandford-Znajek Expansion
Jay Armas, Yangyang Cai, Geoffrey Compére +2
The Blandford-Znajek mechanism is the continuous extraction of energy from a rotating black hole via plasma currents flowing on magnetic field lines threading the horizon. In the d…
