Quasi-normal modes of a Generic-class of magnetically charged regular black hole: scalar and electromagnetic perturbations

In this contribution, we study the quasi-normal modes of a Generic-class of a regular black hole with a magnetic charge in nonlinear electrodynamics, considering scalar and electromagnetic perturbations. The Generic-class contains the Bardeen-class, Hayward-class, and New-class solutions, it can represent a black hole with two horizons or one horizon. First, we obtain the critical values of the magnetic charge and mass; Then, using the third–order WKB approximation, we can determine the dependence of the quasi-normal modes with the parameters of the Generic-class. Finally, the transmission and reflection coefficients of the scattered wave in the third–order WKB approximation are calculated.
