Scale dependence of the effective gravitational constant from functional renormalization group
Ruiqi Liang, Zhoujian Cao, Bing Sun
The general relativity may not be the final theory of gravity. One possible way to look for the gravity theory beyond general relativity is considering variable gravitational const…
The effect of the gravitational constant variation on the phase of gravitational waves
Jiachen An, Bing Sun, Zhoujian Cao
We have previously investigated the effect of the gravitational constant variation on the gravitational wave propagation. Pure theoretical analysis indicates that the leading order…
Influence of dark matter equation of state on the axial gravitational ringing of supermassive black holes
Yuqian Zhao, Bing Sun, Zhoujian Cao +2
In this work, we explore the effects of surrounding dark matter featuring different equations of state on the axial gravitational quasinormal modes of supermassive black holes situ…
Probe the gravitational constant variation via the propagation of gravitational waves
Bing Sun, Jiachen An, Zhoujian Cao
The gravitational constant variation means the breakdown of the strong equivalence principle. As the cornerstone of general relativity, the validity of general relativity can be ex…
The effect of the gravitational constant variation on the propagation of gravitational waves
Jiachen An, Yadong Xue, Zhoujian Cao +2
Since the first detection of gravitational waves, they have been used to investigate various fundamental problems, including the variation of physical constants. Regarding the grav…
The Analytical Solutions of Equatorial Geodesic Motion in Kerr Spacetime
Yan Liu, Bing Sun
The study of Kerr geodesics has a long history, particularly for those occurring within the equatorial plane, which is generally well-understood. However, upon comparison with the…
The Axial Gravitational Ringing of a Spherically Symmetric Black Hole Surrounded by Dark Matter Spike
Yuqian Zhao, Bing Sun, Kai Lin +1
Supermassive black holes at the center of each galaxy may be surrounded by dark matter. Such dark matter admits a spike structure and vanishes at a certain distance from the black…
Extending Gibbons-Werner method to bound orbits of massive particles
Yang Huang, Bing Sun, Zhoujian Cao
The Gibbons-Werner method for the gravitational deflection angle of unbound particles in static spherically symmetric spacetimes is based on Jacobi metric and Gauss-Bonnet theorem.…
Quasi Normal Modes of Black Holes and Detection in Ringdown Process
Yuqian Zhao, Bing Sun, Zhan-Feng Mai +1
Quasi-normal modes (QNMs) of a black hole (BH) are the eigen modes describing the dissipative oscillation of various fields in that spacetime, which can be intrinsically produced b…
Constraint on the fifth force through perihelion precession of planets
Bing Sun, Zhoujian Cao, Lijing Shao
The equivalence principle is important in fundamental physics. The fifth force, as a describing formalism of the equivalence principle, may indicate the property of an unknown theo…
