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…
A new group of low-spin Black Holes and the high pair-instability mass cutoff
Yuan-Zhu Wang, Yin-Jie Li, Shi-Jie Gao +2
Pair-instability supernovae (PISN) will not leave compact remnants and hence yield a mass gap of the black holes. Though a transition point at , separating low-…
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…
Aligned Hierarchical Black Hole Mergers in Active-Galactic-Nuclei Disks Revealed by GWTC-4
Yin-Jie Li, Yuan-Zhu Wang, Shao-Peng Tang +1
The active galactic nucleus (AGN) accretion disks are ideal sites for hierarchical black hole (BH) mergers. To robustly probe such a possibility, we analyze binary black hole merge…
Lensing amplitude anomaly and varying electron mass alleviate the Hubble and tensions
Yi-Ying Wang, Lei Lei, Shao-Peng Tang +1
Cosmological measurements have revealed tensions within the standard CDM model, notably discrepancies in the Hubble constant and parameter. A modified recombination scenar…
GW231123: Likely a product of successive mergers from stellar-mass black holes
Yin-Jie Li, Shao-Peng Tang, Ling-Qin Xue +1
GW231123 is an exceptionally massive binary black hole (BBH) merger with unusually high component spins. Such extreme properties challenge conventional stellar evolution models pre…
Phase transition and nuclear symmetry energy from neutron star observations: Constraints in light of PSR J0614--3329
Shao-Peng Tang, Yong-Jia Huang, Yi-Zhong Fan
The possible occurrence of a first-order hadron-quark phase transition (FOPT) in neutron-star interiors remains an open question. Whether such a transition can be directly tested w…
The maximum mass and rotational kinetic energy of rapidly rotating neutron stars
Shao-Peng Tang, Yong-Jia Huang, Yi-Zhong Fan
Rapid uniformly-rotating neutron stars are expected to be formed for instance in the collapse of some massive stars, the accretion of compact object binaries, and double neutron st…
Revealing the - Correlation among Coalescing Binary Black Holes and Tentative Evidence for AGN-driven Hierarchical Mergers
Yin-Jie Li, Yuan-Zhu Wang, Shao-Peng Tang +2
The origin of the correlation between the effective spins () and mass ratios () of LIGO-Virgo-KAGRA's binary black holes (BBHs) is still an open question. Motivated…
