Massive scalar fields in eccentric regime: Detectability and constraints from LISA observations of extreme mass-ratio inspirals
Tieguang Zi, Shailesh Kumar, Jun-Kun Zhao +3
Extreme mass-ratio inspirals (EMRIs) are among the most promising sources for future space-based gravitational wave (GW) observatories and provide sensitive probes of additional fu…
A practical Bayesian method for gravitational-wave ringdown analysis with multiple modes
Yiming Dong, Ziming Wang, Hai-Tian Wang +2
Gravitational-wave (GW) ringdown signals from black holes (BHs) encode crucial information about the gravitational dynamics in the strong-field regime, which offers unique insights…
Accuracy of numerical relativity waveforms with respect to space-based gravitational wave detectors
Zun Wang, Junjie Zhao, Zhoujian Cao
As with the laser interferometer gravitational-wave observatory (LIGO), the matched filtering technique will be critical to the data analysis of gravitational wave detection by spa…
Simultaneous bounds on the gravitational dipole radiation and varying gravitational constant from compact binary inspirals
Ziming Wang, Junjie Zhao, Zihe An +2
Compact binaries are an important class of gravitational-wave (GW) sources that can be detected by current and future GW observatories. They provide a testbed for general relativit…
Extending the Fisher Information Matrix in Gravitational-wave Data Analysis
Ziming Wang, Chang Liu, Junjie Zhao +1
The Fisher information matrix (FM) plays an important role in forecasts and inferences in many areas of physics. While giving fast parameter estimation with the Gaussian likelihood…
Probing dipole radiation from binary neutron stars with ground-based laser-interferometer and atom-interferometer gravitational-wave observatories
Junjie Zhao, Lijing Shao, Yong Gao +3
Atom-interferometer gravitational-wave (GW) observatory, as a new design of ground-based GW detector for the near future, is sensitive at a relatively low frequency for GW observat…
Extended reduced-order surrogate models for scalar-tensor gravity in the strong field and applications to binary pulsars and gravitational waves
Minghao Guo, Junjie Zhao, Lijing Shao
Statistically sound tests of scalar-tensor gravity theories in the strong-field regime usually involves computationally intensive calculations. In this study, we construct a reduce…
Tests of conservation laws in post-Newtonian gravity with binary pulsars
Xueli Miao, Junjie Zhao, Lijing Shao +3
General relativity is a fully conservative theory, but there exist other possible metric theories of gravity. We consider non-conservative ones with a parameterized post-Newtonian…
Neutron Star Structure in the Minimal Gravitational Standard-Model Extension and the Implication to Continuous Gravitational Waves
Rui Xu, Junjie Zhao, Lijing Shao
Tiny violation of Lorentz invariance has been the subject of theoretic study and experimental test for a long time. We use the Standard-Model Extension (SME) framework to investiga…
Reduced-order surrogate models for scalar-tensor gravity in the strong field and applications to binary pulsars and GW170817
Junjie Zhao, Lijing Shao, Zhoujian Cao +1
We investigate the scalar-tensor gravity of Damour and Esposito-Farèse (DEF), which predicts non-trivial phenomena in the nonperturbative strong-field regime for neutron stars (NSs…
