Quasi-normal modes of Ayon–Beato Garcia regular black holes for scalar field

In this paper, we compute quasi-normal modes of ABG black holes (which has a nonlinear electrodynamical source) using the WKB methods and AIM. A comparison between the spectrum of QNMs calculated by both methods is made. We analyse how the spectrum of QNMs depends on the black hole parameters, multipole number and overtone number and establish that the ABG black hole is stable against the scalar field.
