Quasinormal modes and greybody factors of a four-dimensional Lifshitz black hole with z=0

Understand

We study scalar perturbations for a four-dimensional asymptotically Lifshitz black hole in conformal gravity with dynamical exponent z=0, and spherical topology for the transverse section, and we find analytically and numerically the quasinormal modes for scalar fields for some special cases.

• Then, we study the stability of these black holes under scalar field perturbations and the greybody factors.
