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…
