Schwarzschild Lensing From Geodesic Deviation
Zhao Li, Xiao Guo, Tan Liu +2
We revisit the gravitational lensing of light or gravitational waves by Schwarzschild black hole in geometric optics. Instead of a single massless particle, we investigate the coll…
Gravitational Radiation from Eccentric Binary Black Hole System in Dynamical Chern-Simons Gravity
Zhao Li, Jin Qiao, Tan Liu +4
Dynamical Chern-Simons (DCS) gravity, a typical parity-violating gravitational theory, modifies both the generation and propagation of gravitational waves from general relativity (…
Effects of spin-orbit coupling on gravitational waveforms from a triaxial non-aligned neutron star in a binary system
Wen-Fan Feng, Tan Liu, Jie-Wen Chen +2
Spinning neutron stars (NSs) can emit continuous gravitational waves (GWs) that carry a wealth of information about the compact object. If such a signal is detected, it will provid…
Gravitational Waveform and Polarization from Binary Black Hole Inspiral in Dynamical Chern-Simons Gravity: From Generation to Propagation
Zhao Li, Jin Qiao, Tan Liu +2
We calculate the gravitational waveform radiated from spinning black holes (BHs) binary in dynamical Chern-Simons (dCS) gravity. The equation of motion (EOM) of the spinining binar…
Gravitational waveforms from the inspiral of compact binaries in the Brans-Dicke theory in an expanding Universe
Tan Liu, Yan Wang, Wen Zhao
In modified gravity theories, such as the Brans-Dicke theory, the background evolution of the Universe and the perturbation around it are different from that in general relativity.…

The screened modified gravity (SMG) is a unified theoretical framework, which describes the scalar-tensor gravity with screening mechanism. Based on the gravitational-wave (GW) wav…
Model-independent test of the parity symmetry of gravity with gravitational waves
Wen Zhao, Tan Liu, Linqing Wen +4
Gravitational wave (GW) data can be used to test the parity symmetry of gravity by investigating the difference between left-hand and right-hand circular polarization modes. In thi…
