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-…
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…
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…
Constraints on parity and Lorentz violations from gravitational waves: a comparison between single-parameter and multi-parameter analysis
Wei-Hua Guo, Yuan-Zhu Wang, Tao Zhu +1
The growing catalog of gravitational wave (GW) detections by the LIGO-Virgo-KAGRA Collaboration enables increasingly stringent tests of general relativity, particularly regarding p…
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…
