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…
Polarization-dependent observational signatures of Weyl-coupled photons around a black hole
Mao-Yuan Wan, Chen Wu
A photon coupled non-minimally to the Weyl tensor propagates differently in its two linear polarization states: the vacuum around a black hole becomes a birefringent medium. On a S…
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…
Geodesic structure of a noncommutative black hole
Zihan Xi, Chen Wu, Wenjun Guo
This paper explores the metric of Piero Nicolini's noncommutative black hole spacetime, calculates its effective potential, and presents the corresponding potential curve. By analy…
Different Regular Black Holes: Geodesic Structures of Test Particles
Zihan Xi, Chen Wu, Wenjun Guo
This paper investigates the metric of previously proposed regular black holes, calculates their effective potentials, and plots the curves of the effective potentials. By determini…
