Null test of general relativity based on gravitational waves
Dawen Chen, Zeyuan Kang, Zhoujian Cao
Several hundreds of gravitational wave events have been detected. They are good tools to investigate various fundamental problems, including tests of general relativity (GR) theory…
Solving Hamiltonian Constraint Equation with Physics-Informed Neural Networks
Yu-Chen Zhou, Hao Ma, Zhoujian Cao +6
Numerical relativity (NR), solving Einstein equation numerically, plays an important role in source modelling for gravitational wave astronomy. Traditional methods for NR including…
Eccentricity enables the earliest warning and localization of gravitational waves with ground-based detectors
Tao Yang, Rong-Gen Cai, Zhoujian Cao +1
The early and precise localization of gravitational waves (GWs) is pivotal in detecting their electromagnetic (EM) counterparts, especially for binary neutron stars (BNS) and neutr…
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…
