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…
Constraining the cosmological parameters using gravitational wave observations of massive black hole binaries and statistical redshift information
Liang-Gui Zhu, Yi-Ming Hu, Hai-Tian Wang +4
Space-borne gravitational wave detectors like TianQin are expected to detect GW signals emitted by the mergers of massive black hole binaries. Luminosity distance information can b…
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…
Science with the TianQin Observatory: Preliminary results on Galactic double white dwarf binaries
Shun-Jia Huang, Yi-Ming Hu, Valeriya Korol +6
We explore the prospects of detecting of Galactic double white dwarf (DWD) binaries with the space-based gravitational wave (GW) observatory TianQin. In this work, we analyze both…
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…
