Analytic quasinormal frequencies of the regular Simpson–Visser black hole
Zainab Malik
Abstract
By expanding in powers of the inverse multipole number, we derive compact analytic expressions for the quasinormal modes of scalar and electromagnetic perturbations around regular Simpson–Visser black holes. These analytic formulas offer sufficient accuracy for the first and higher multipoles, except when the black hole is in a near-extremal state. The correspondence between null geodesics and high-frequency quasinormal modes is confirmed for the case under consideration. As an application, we show that Simpson–Visser black holes respect the Hod’s bound on the damping rate of the fundamental quasinormal mode.
