Detection of astrophysical gravitational wave sources by TianQin and LISA
Alejandro Torres-Orjuela, Shun-Jia Huang, Zheng-Cheng Liang +5
TianQin and LISA are space-based laser interferometer gravitational wave (GW) detectors planned to be launched in the mid-2030s. Both detectors will detect low-frequency GWs around…
Analytic Kludge Waveforms for Extreme Mass Ratio Inspirals of Charged Object around Kerr-Newman Black Hole
Tieguang Zi, Ziqi Zhou, Hai-Tian Wang +3
We derive the approximate, ``analytic-kludge'' (AK) waveforms for the inspiral of a charged stellar-mass compact object (CO) into a charged massive Kerr-Newman (KN) black hole (BH)…
Probing chromatic onsets of gravitational wave overtones
Hai-Tian Wang, Yi-Ming Hu, Peng-Cheng Li +1
The ringdown data of both GW150914 and GW190521\_074359 (GW190521r) show evidence supporting the presence of overtone. Previous studies all adopt a fundamental assumption, which we…
Quasinormal-modes of the Kerr-Newman black hole: GW150914 and fundamental physics implications
Hai-Tian Wang, Shao-Peng Tang, Peng-Cheng Li +1
We develop an analytical ringdown waveform model, including both the fundamental and the overtone quasinormal modes, for charged black holes and show that it is precise enough to a…
Tight constraints on Einstein-dilation-Gauss-Bonnet gravity from GW190412 and GW190814
Hai-Tian Wang, Shao-Peng Tang, Peng-Cheng Li +2
Gravitational-wave (GW) data can be used to test general relativity in the highly nonlinear and strong field regime. Modified gravity theories such as Einstein-dilation-Gauss-Bonne…
The TianQin project: current progress on science and technology
Jianwei Mei, Yan-Zheng Bai, Jiahui Bao +103
TianQin is a planned space-based gravitational wave (GW) observatory consisting of three earth orbiting satellites with an orbital radius of about . The satellites w…
Constraining modified gravity with ringdown signals: an explicit example
Jiahui Bao, Changfu Shi, Haitian Wang +4
An explicit example is found showing how a modified theory of gravity can be constrained with the ringdown signals from merger of binary black holes. This has been made possible by…
Science with the TianQin observatory: Preliminary results on testing the no-hair theorem with ringdown signals
Changfu Shi, Jiahui Bao, Haitian Wang +6
We study the capability of the space-based gravitational wave observatory TianQin to test the no-hair theorem of General Relativity, using the ringdown signal from the coalescence…
