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…

We investigate scalar perturbations of the static loop quantum black bounce (LQBB) spacetime with multipole index , focusing on time-domain signals and fundamental quasinormal…
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…
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…
