Black hole correspondences of quasi-topological gravity : Shadows, quasinormal modes, graybody factors
Sihao Fan, Chen Wu, Wenjun Guo
Within the framework of quasi-topological gravity, we systematically investigate the correspondences among three classes of observables---the shadow, the quasinormal modes, and the…

Graybody factors and absorption cross-sections of non-exchange black holes in Instein-coupled scalar fields
Sihao Fan, Wenjun Guo, Chen Wu
This paper studies scalar field perturbations coupled with Einstein tensors of non-exchange black holes. We use the polarization method to calculate graybody factors and absorption…

Absorption and scattering of massless scalar waves by black holes in quasi-topological gravity
SiHao Fan, Chen Wu, WenJun Guo
We consider massless scalar field perturbations of regular black holes in quasi-topological gravity. After reviewing various regular black hole solutions, we compute the total abso…
