Quasinormal modes of magnetized black hole

Abstract

We investigate the quasinormal modes (QNMs) of scalar, electromagnetic, and gravitational perturbations in the spacetime of a magnetized black hole. The analysis demonstrates how external magnetic fields modify the QNM spectrum, with implications for the stability of black holes and possible observational signatures. Results show significant differences compared to non-magnetized black holes, offering new insights into astrophysical processes involving strong magnetic fields.
