Bekenstein--Hod Bound: A Confirmation from GW250114
Hai-Tian Wang, Shao-Peng Tang, Yi-Zhong Fan
Black holes link gravity, thermodynamics and information via limits on the relaxation rate of a perturbed system. The Bekenstein-Hod bound imposes a minimum relaxation time at fixe…
Verification of the Black Hole Area Law with GW230814
Shao-Peng Tang, Hai-Tian Wang, Yin-Jie Li +1
We present an observational confirmation of Hawking's black-hole area theorem using the newly released gravitational-wave data from the GWTC-4.0. We analyze the high signal-to-nois…
Detection of a Higher Harmonic Quasi-normal Mode in the Ringdown Signal of GW231123
Hai-Tian Wang, Shao-Peng Tang, Peng-Cheng Li +1
The ringdown phase of a gravitational wave signal from a binary black hole merger offers a unique laboratory for testing general relativity in the strong-field regime and probing t…
Constraints on Einstein-dilation-Gauss-Bonnet gravity and electric charge of compact binary systems from GW230529
Bo Gao, Shao-Peng Tang, Hai-Tian Wang +2
In this work, we study the implications of GW230529 on gravity theories and the charge of black holes. The GW230529, which was initially released in O4a, is most likely neutron sta…
Prospects of Identifying Hierarchical Triple Mergers for the Third-generation Ground-based Detectors
Bo Gao, Shao-Peng Tang, Jingzhi Yan +1
A hierarchical triple merger (HTM) constitutes a type of event in which two successive black hole (BH) mergers occur sequentially within the observational window of gravitational w…
Hierarchical triple mergers: testing Hawking's area theorem with the inspiral signals
Shao-Peng Tang, Yi-Zhong Fan, Da-Ming Wei
Hawking's area theorem is one of the fundamental laws of black holes (BHs), which has been tested at a confidence level of with gravitational wave (GW) observations by…
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…
