Constraining Lorentz symmetry breaking in bumblebee gravity with extreme mass-ratio inspirals
Sheng Long, Zhong-wu Xia, Huajie Gong +3
Extreme mass-ratio inspirals (EMRIs), with their long-lived and highly relativistic orbital evolution, can probe strong-field spacetime geometry and provide an important means to t…
Bayesian inference for tidal heating with extreme mass ratio inspirals
Zhong-Wu Xia, Sheng Long, Qiyuan Pan +2
Extreme mass ratio inspirals (EMRIs) provide unique probes of near-horizon dissipation through the tidal heating. We present a full Bayesian analysis of tidal heating in equatorial…
Effective metric for binaries in framework of EOB theory to fifth PM order
Jiliang Jing, Weike Deng, Sheng Long
To establish a self-consistent effective one-body (EOB) theory that describes the dynamical evolution of binary systems based on the post-Minkowskian (PM) approximation, where the…
Quasinormal modes of scalar, electromagnetic, and gravitational perturbations in slowly rotating Kalb-Ramond black holes
Weike Deng, Wentao Liu, Kui Xiao +1
We investigate quasinormal modes (QNMs) of scalar, electromagnetic, and axial gravitational perturbations in slowly rotating Kalb-Ramond (KR) black holes, where an antisymmetric te…
Scalar perturbation around a rotating Kalb-Ramond BTZ black hole
Zhong-Wu Xia, Sheng Long, Huajie Gong +2
We investigate the scalar perturbation of a newly proposed Kalb-Ramond (KR) BTZ-like black hole. After the separation of variables for the Klein-Gordon equation, we find that the r…
Gravitational waveforms from periodic orbits around a charged black hole with scalar hair
Weike Deng, Sheng Long, Qin Tan +1
We investigate geodesic motion and gravitational-wave signatures of charged black holes with scalar hair. Using the effective potential approach, we analyze marginally bound orbits…
