Quasinormal modes of a rotating loop quantum black hole
Zhongzhinan Dong, Shulan Li, Dan Zhang +1
We investigate the quasinormal modes of a massless scalar field on an effective rotating loop quantum black hole background, constructed from a covariant spherical model via an imp…
Assessing EMRI Detectability of the Rotating Quantum Oppenheimer-Snyder Black Hole
Dan Zhang, Shulan Li, Guoyang Fu +1
This letter presents an assessment of quantum gravity effects on extreme-mass-ratio inspirals (EMRIs) for the rotating quantum Oppenheimer-Snyder (qOS) black hole. Employing the ad…
Imprints of quantum gravity effects on gravitational waves: a comparative study using extreme mass-ratio inspirals
Ruo-Ting Chen, Guoyang Fu, Dan Zhang +1
Within a generally covariant Hamiltonian framework of loop quantum gravity (LQG), two black hole models parameterized by a quantum correction have recently been constructed. U…
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…
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…
Quasinormal modes of a charged loop quantum black hole
Li-Gang Zhu, Guoyang Fu, Shulan Li +2
This study presents a systematic investigation of quasinormal modes (QNMs) for probe fields-massless/massive scalar and Dirac fields-around a charged loop quantum gravity black hol…
