pespace: A new tool of GPU-accelerated and auto-differentiable response generation and likelihood evaluation for space-borne gravitational wave detectors
Rui Niu, Chang Feng, Wen Zhao
Space-borne gravitational wave detectors will expand the scope of gravitational wave astronomy to the milli-Hertz band in the near future. The development of data analysis software…
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…
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…
