Resonant bound orbits and kludge waveforms in rotating Konoplya-Zhidenko black hole spacetime
Qiyu Dai, Xiongjun Fang, Xiao-Mei Kuang +1
We investigate timelike bound motion, resonant periodic orbits, and their gravitational-wave signatures in the rotating Konoplya-Zhidenko (KZ) black hole spacetime. Using the separ…
Kerr-MOG-(A)dS black hole and its shadow in scalar-tensor-vector gravity theory
Wentao Liu, Di Wu, Xiongjun Fang +2
The scalar-tensor-vector gravity (STVG) theory has attracted significant interest due to its ability to effectively address the issue of galaxy rotation curves and clusters of gala…
Lorentz violation induces isospectrality breaking in Einstein-Bumblebee gravity theory
Wentao Liu, Xiongjun Fang, Jiliang Jing +1
In this paper, we investigate the quasinormal modes (QNMs) of a Lorentz-violating spacetime, factoring in a cosmological constant, within the framework of Einstein-Bumblebee gravit…
Gravito-electromagnetic perturbations of MOG black holes with a cosmological constant: Quasinormal modes and Ringdown waveforms
Wentao Liu, Xiongjun Fang, Jiliang Jing +1
In this paper, we present a black hole solution with a cosmological constant in the Scalar-Tensor-Vector Modified Gravity (MOG) theory, where the strength of the gravitational cons…
The Quasinormal Modes and Isospectrality of Bardeen (Anti-) de Sitter Black Holes
Ying Zhao, Wentao Liu, Chao Zhang +2
Black holes (BHs) exhibiting coordinate singularities but lacking essential singularities throughout the entire spacetime are referred to as regular black holes (RBHs). The initial…
QNMs of slowly rotating Einstein-Bumblebee Black Hole
Wentao Liu, Xiongjun Fang, Jiliang Jing +1
We have studied the quasinormal modes (QNMs) of a slowly rotating black hole with Lorentz-violating parameter in Einstein-bumblebee gravity. We analyse the slow rotation approximat…
