Smoking-gun evidence for hierarchical black-hole mergers
Yin-Jie Li, Yuan-Zhu Wang, Shao-Peng Tang +1
How stellar-mass black holes grow after their birth is a central open question in astrophysics. Gravitational-wave observations have revealed a subpopulation of coalescing black ho…
Tests of general relativity at the fourth post-Newtonian order with GW230627 and GW250114
Xi-Min Liang, Yuan-Zhu Wang, Tao Zhu +2
Gravitational wave (GW) observations provide an unprecedented laboratory for testing general relativity (GR) in the strong-field, highly dynamic, and relativistic regimes. Within t…
Neutron Star Merger Rates from Multi-messenger Observations: Clues to the Physical Origin of the Short and Long-short Gamma-ray Bursts
Zhi-Ping Jin, Yuan-Zhu Wang, Yin-Jie Li +4
Short and long-short gamma-ray bursts (GRBs) are widely believed to be powered by neutron star mergers. In this work, we calculate local rate of such GRBs and find a relatively hig…
Reassessing the Spin of Second-born Black Holes in Coalescing Binary Black Holes and Its Connection to the chi_eff-q Correlation
Zi-Yuan Wang, Ying Qin, Rui-Chong Hu +3
The mass ratio q and effective inspiral spin chi_eff of binary black hole (BBH) mergers in GWTC-4.0 show a weaker anti-correlation than in GWTC-3.0, motivating investigation of its…
Stable Case BB/BC Mass Transfer to Form GW190425-like Massive Binary Neutron Star Mergers
Ying Qin, Jin-Ping Zhu, Georges Meynet +14
On April 25th, 2019, the LIGO-Virgo Collaboration discovered a Gravitational-wave (GW) signal from a binary neutron star (BNS) merger, i.e., GW190425. Due to the inferred large tot…
Hypercritical Accretion for Black Hole High Spin in Cygnus X-1
Ying Qin, Xinwen Shu, Shuangxi Yi +1
Recent observations of AdLIGO and Virgo have shown that the spin measurements in binary black hole (BH) systems are typically small, which is consistent with the predictions by the…
