Constraining the dynamical Chern-Simons gravity with future gravitational wave detectors
Xinyi Che, Xiangyu Lyu, Changfu Shi
Dynamical Chern-Simons gravity, a parity-violating modification of general relativity, is regarded as a low-energy effective theory arising from string theory. Gravitational waves…
Detecting relativistic black hole collisions near a massive black hole
Yirong Fang, Changfu Shi, Jianwei Mei
Relativistic black hole collisions are one of the most dramatic astrophysical events that can be imagined. They could provide the ideal condition for searching for possible new phy…
Probing AGN Disks Density Profiles through Gravitational Wave Observations
Xiangyu Lyu, En-Kun Li, Changfu Shi +1
Massive black holes surrounded by a gaseous disk have been a prevailing model to explain a wide spectrum of astrophysical phenomena related to active galactic nucle (AGNs). However…
Contribution from Nonlinear Quasi-normal Modes in GW250114
Yuxin Yang, Changfu Shi, Yi-Ming Hu
We report evidence for nonlinear gravitational effects in the ringdown signal of gravitational wave event GW250114. Using Bayesian inference, we find that the inclusion of a nonlin…
