Exceptional points and near-extremal boundary response in rotating BTZ black holes
Sheng Long, Yu Shi, Zhongwu Xia +4
We investigate whether the coalescence of long-lived quasinormal modes enhances the boundary response of rotating BTZ black holes. Using exact scalar solutions with mixed Robin bou…
Echoes and quasinormal modes for static loop quantum black bounces
Huajie Gong, Guoyang Fu, Shulan Li +3
We investigate scalar perturbations of the static loop quantum black bounce (LQBB) spacetime with multipole index , focusing on time-domain signals and fundamental quasinormal…
Images of Braneworld black holes with radiatively inefficient accretion flows
Chengjia Chen, Yin Hao, Zelin Zhang +2
Horizon-scale imaging acts as a transformative tool for probing spacetime geometry, enabling stringent tests of gravitational theories in the strong-field regime. The Casadio-Fabbr…
Stationary scalar clouds around a rotating Kalb-Ramond BTZ black hole
Rui Ding, Fangli Quan, Zhong-Wu Xia +2
We investigate the scalar clouds around a rotating Kalb-Ramond (KR) BTZ black hole under Robin boundary conditions. The clouds are obtained as stationary bound states at the superr…
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…
Probing Quantum Gravity effects with Extreme Mass Ratio Inspirals around Rotating Hayward Black Holes
Dan Zhang, Chao Zhang, Qiyuan Pan +2
We investigate extreme mass-ratio inspirals (EMRIs) around a rotating Hayward black hole to assess the detectability of signatures arising from quantum gravity.The quantum paramete…
Scalar perturbation around a rotating Kalb-Ramond BTZ black hole
Zhong-Wu Xia, Sheng Long, Huajie Gong +2
We investigate the scalar perturbation of a newly proposed Kalb-Ramond (KR) BTZ-like black hole. After the separation of variables for the Klein-Gordon equation, we find that the r…
Echoes from the Minkowski-core spacetime
Dan Zhang, Qin Tan, Guoyang Fu +3
In this study, we construct a class of horizonless exotic compact objects (ECOs) with Minkowski core, classifying them as either photon sphere ECOs (PS ECOs) or photon sphere lacki…
Gravitational waveforms from periodic orbits around a novel regular black hole
Huajie Gong, Sheng Long, Xi-Jing Wang +3
We explore potential quantum gravity signatures by studying periodic orbits and their GW emissions around a novel regular black hole (BH) featuring a Minkowski core. Using a ration…
Observational appearances of an inner extremal regular black hole illuminated by various accretion flows
Dan Zhang, Guoyang Fu, Xi-Jing Wang +3
This paper investigates the observational appearances of an inner extremal regular black hole(IERBH) illuminated by various types of accretion models. The study reveals that when t…
Quasinormal modes of a regular black hole with sub-Planckian curvature
Dan Zhang, Huajie Gong, Guoyang Fu +2
This paper explores the properties of the quasinormal modes (QNMs) of a regular black hole(BH) characterized by a Minkowski core and sub-Planckian curvature. When focusing on a spe…
