Quasinormal modes of the Hayward black hole surrounded by quintessence: Scalar, electromagnetic and gravitational perturbations

Abstract

In this paper, we study the quasinormal modes for scalar, electromagnetic, and gravita- tional axial perturbations in the Hayward regular black hole surrounded by quintessence (HBH-ωq). Using the third-order WKB approximation, we can determine the dependence of the quasinormal modes on the parameters of the regular black hole and the parame- ters on the test fields. We also determine the greybody factor, giving transmission and reflection coefficients of the scattered wave through the effective potentials in the WKB approximation using numerical analysis.
