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…
Forecast Analysis of Astrophysical Stochastic Gravitational Wave Background beyond general relativity: A Case Study on Brans-Dicke Gravity
Ran Chen, Zhao Li, Yin-Jie Li +4
Scalar-tensor gravity, exemplified by Brans-Dicke (BD) gravity, introduces additional scalar polarization modes that contribute scalar radiation alongside tensor modes. We conduct…
Extracting overlapping gravitational-wave signals of galactic compact binaries: a mini review
Rui Niu, Wen Zhao
Gravitational wave (GW) observations have provided a novel tool to explore the universe. In the near future, space-borne detectors will further open the window of low-frequency GW…
Constraining the modified friction in gravitational wave propagation with precessing black hole binaries
Chunbo Lin, Tao Zhu, Rui Niu +1
A broad class of modified gravities can result in a modified friction effect in the propagation of gravitational waves (GWs). This effect changes the amplitude-damping rate of GWs…
Power spectra and circular polarization of primordial gravitational waves with parity and Lorentz violations
Tian-Chen Li, Tao Zhu, Wen Zhao +1
The violations of parity and Lorentz symmetries in gravity can change the propagating properties of gravitational waves (GWs) in the cosmological background, which can arise from a…
The Multi-parameter Test of Gravitational Wave Dispersion with Principal Component Analysis
Zhi-Chu Ma, Rui Niu, Wen Zhao
In this work, we consider a conventional test of gravitational wave (GW) propagation which is based on the phenomenological parameterized dispersion relation to describe potential…
