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 and echoes of a double braneworld
Qin Tan, Sheng Long, Weike Deng +1
In this work, we study the gravitational quasinormal modes and the gravitational echoes of a double braneworld. The double braneworld is a kind of split thick brane, which is cruci…
Motion of spinning particles around black hole in a dark matter halo
Qin Tan, Weike Deng, Sheng Long +1
The motion of a rapidly rotating object in curved spacetime is affected by the spin-curvature force, an effect captured in the motion of spinning test particles. Recently, Cardoso…
Graviscalar quasinormal modes and asymptotic tails of a thick brane
Qin Tan, Sheng Long, Weike Deng +1
In this work, we investigate the graviscalar quasinormal modes (QNMs) and their asymptotic tail behavior of a thick brane. Considering the scalar perturbations of the thick brane m…
