Gauge invariant perturbations of general spherically symmetric spacetimes
TL;DR: In this paper , the authors provide analytical calculations of metric perturbation in general spherically symmetric spacetimes, which can be applied to various cases, including the Effective-One-Body problem.
Journal ArticleDOI
QNMs of slowly rotating Einstein–Bumblebee black hole
TL;DR: In this paper , the authors analyzed the slow rotation approximation of the rotating black hole in the Einstein-bumblebee gravity, and obtained the master equations for scalar, vector and axial gravitational perturbation, respectively.
The Quasinormal Modes and Isospectrality of Bardeen (Anti-) de Sitter Black Holes
TL;DR: In this article , the authors investigated the gravitational perturbations, including the axial and polar sectors, of the Bardeen (Anti-) de Sitter black holes, and derived the master equations with source terms for both axial, polar, and global perturbation.
Quasinormal Modes of Black Holes in the Scalar-Tensor-Vector Modified Gravity with a Cosmological Constant
TL;DR: In this paper , the authors derived the master equations for gravito-electromagnetic perturbations and numerically solved for the Quasinormal Mode (QNM) spectrum and the ringdown waveforms.
Gravito-electromagnetic perturbations of MOG black holes with a cosmological constant: Quasinormal modes and Ringdown waveforms
TL;DR: In this paper , the authors presented a black hole solution with a cosmological constant in the Scalar-Tensor-Vector Modified Gravity (MOG) theory, where the strength of the gravitational constant is determined by $G = G_\text{N}(1+\alpha)$.
