Ensemble-Based Residual Tests of GW231123 across Waveform Models
Dicong Liang, Hai-Tian Wang, Junlin Qin +3
GW231123 is an exceptional gravitational wave event for which different waveform models yield significantly different inferred source parameters. Residual tests provide a direct wa…
Cracking Gravitational Wave Multiple Ringdown Modes in Space
Ziming Wang, Han Wang, Yuxin Yang +4
Ringdown signals from perturbed black holes (BHs) offer a clean window into BH spacetime, strong-field gravity, and fundamental physics. Presently the quasi-normal modes of stellar…
A Robust and Efficient F-statistic-based Framework for Consistent Bayesian Inference of Compact Binary Coalescences
Hai-Tian Wang
We present a comprehensive investigation of the F-statistic method for parameter estimation of gravitational wave (GW) signals from compact binary coalescences. By analytically max…
First Overtone Mode in the Ringdown Signal of GW231028
Hai-Tian Wang
The properties of a remnant black hole can be probed by analyzing the gravitational waves emitted during its ringdown phase. This signal provides a direct test of general relativit…
Constraints on parity and Lorentz violations from gravitational waves: a comparison between single-parameter and multi-parameter analysis
Wei-Hua Guo, Yuan-Zhu Wang, Tao Zhu +1
The growing catalog of gravitational wave (GW) detections by the LIGO-Virgo-KAGRA Collaboration enables increasingly stringent tests of general relativity, particularly regarding p…
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…
Reanalyzing the ringdown signal of GW150914 using the F-statistic method
Hai-Tian Wang, Ziming Wang, Yiming Dong +2
The ringdown phase of a gravitational wave (GW) signal from a binary black hole merger provides valuable insights into the properties of the final black hole and serves as a critic…
Gravitational wave ringdown analysis using the -statistic
Hai-Tian Wang, Garvin Yim, Xian Chen +1
After the final stage of the merger of two black holes, the ringdown signal takes an important role on providing information about the gravitational dynamics in strong field. We in…
Gravitational Wave Astronomy With TianQin
En-Kun Li, Shuai Liu, Alejandro Torres-Orjuela +50
The opening of the gravitational wave window has significantly enhanced our capacity to explore the universe's most extreme and dynamic sector. In the mHz frequency range, a divers…
Comparison between time-domain and frequency-domain Bayesian inferences to inspiral-merger-ringdown gravitational-wave signals
Hai-Tian Wang, Lijing Shao
Time-domain (TD) Bayesian inference is important in ringdown analysis for gravitational wave (GW) astronomy. The validity of this method has been well studied by Isi and Farr [1].…
Effect of Noise Estimation in Time-Domain Ringdown Analysis: A Case Study with GW150914
Hai-Tian Wang, Lijing Shao
Accurate noise estimation from gravitational wave (GW) data is critical for Bayesian inference. However, recent studies on ringdown signal, such as those by Isi et al. [1], Cotesta…
Constraints on charged black holes from merger-ringdown signals in GWTC-3 and prospects for the Einstein Telescope
Hua-Peng Gu, Hai-Tian Wang, Lijing Shao
Whether astrophysical black holes (BHs) can have charge is a question to be addressed by observations. In the era of gravitational wave (GW) astronomy, one can constrain the charge…
