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…
