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…
The images of Brans-Dicke-Kerr type naked singularities
Fen Long, Weike Deng, Xin Qin +2
We have studied the images of the Brans-Dicke-Kerr spacetime with a dimensionless Brans-Dicke parameter , which belongs to axisymmetric rotating solutions in the Brans-Dicke 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…
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…
Quasinormal Modes of Massive Scalar Perturbations in Slow-Rotation Bumblebee Black Holes with Traceless Conformal Electrodynamics
Yassine Sekhmani, Wentao Liu, Weike Deng +1
We study electrically charged, slowly rotating black hole solutions in Einstein-Bumblebee gravity coupled to the traceless (conformal) ModMax nonlinear electrodynamics. By adopting…
Effective one-body theory of spinless binary evolution dynamics
Jiliang Jing, Sheng Long, Weike Deng +1
The effective one-body (EOB) theory provides an innovative framework for analyzing the dynamics of binary systems, as articulated by Hamilton's equations. This paper investigates a…
Scalar-gravitational quasinormal modes and echoes in a five dimensional thick brane
Weike Deng, Sheng Long, Qin Tan +2
The scalar perturbations of thick braneworld models provide critical insights into their matter-geometry relationship, distinct from tensor modes. This work systematically investig…
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…
