Eigenvalue repulsions and quasinormal mode spectra of Kerr-Newman: an extended study
A bstract The frequency spectra of the gravito-electromagnetic perturbations of the Kerr-Newman (KN) black hole with the slowest decay rate have been computed recently. It has been found that KN has two families — the photon sphere and the near-horizon families — of quasinormal modes (QNMs), which display the interesting …
