Scalar field perturbations of a Lifshitz black hole in conformal gravity in three dimensions

Catalán M.; Vasquez, Y

Abstract

We study the reflection and transmission coefficients and the absorption cross section for scalar fields in the background of a Lifshitz black hole in three-dimensional conformal gravity with z = 0, and we show that the absorption cross section vanishes at the low-and high-frequency limits. Also, we determine the quasinormal modes of scalar perturbations, and then we study the stability of these black holes under scalar field perturbations.
