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…

The Heavier the Faster: A Sub-population of Heavy, Rapidly Spinning and Quickly Evolving Binary Black Holes
Wei-Hua Guo, Yin-Jie Li, Yuan-Zhu Wang +4
The spins of binary black holes (BBHs) measured from gravitational waves carry notable information of the formation pathways. Here we propose a quantity "dimensionless net spin" ($…
