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…
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…
Quasinormal Modes of a Massive Scalar Field in Slowly Rotating Einstein-Bumblebee Black Holes
Weike Deng, Wentao Liu, Fen Long +2
In this study, we examine the impacts of black hole spin, Lorentz-violating parameter, and the scalar field's mass on quasinormal modes (QNMs) of rotating Einstein-Bumblebee black…
