Energy extraction from NED-deformed rotating black holes via the Comisso-Asenjo reconnection process
The study quantifies how nonlinear electrodynamics (NED) deformations affect energy extraction from rotating black holes by analyzing magnetic reconnection. The research uses geometric probes like shadow size and quasinormal modes to set ceilings on the deformation parameter g/M. It also derives a spin-dependent extraction bound based on magnetic reconnection, providing complementary constraints to test the physics inside the black hole's ergoregion.
