Electromagnetic perturbations of black holes in general relativity coupled to nonlinear electrodynamics
Electromagnetic perturbations of black holes in general relativity coupled to nonlinear electrodynamics
The electromagnetic (EM) perturbations of the black hole solutions in general relativity coupled to nonlinear electrodynamics (NED) are studied for both electrically and magnetically charged black holes, assuming that the EM perturbations do not alter the spacetime geometry. It is shown that the effective potentials of the electrically and magnetically …
