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…
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…
Constraining string cosmology with the gravitational-wave background using the NANOGrav 15-year data set
Qin Tan, You Wu, Lang Liu
The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) collaboration has recently reported strong evidence for a signal at nanohertz, potentially the first det…
