The Origins of Causality Violations in Force-free Simulations of Black Hole Magnetospheres
The Origins of Causality Violations in Force-free Simulations of Black Hole Magnetospheres
Recent simulations of force-free, degenerate electrodynamic (ffde) black hole magnetospheres indicate that the fast mode radiated from (or near) the event horizon can modify the global potential difference in the poloidal direction orthogonal to the magnetic field, V, in a black hole magnetosphere. By contrast, in MHD (meaning perfect magnetohydrodynamics …
