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

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 limit. Also, we determine the quasinormal modes of scalar perturbations and then we study the stability of these black holes under scalar field perturbations.
