A Minkowski-core black hole with cosmological constant and electric charge
Wen-Zheng Chen, Shulan Li, Jian-Pin Wu +1
Within a covariant effective Hamiltonian framework, we employ an inverse construction to derive the gravitational Hamiltonian constraint for a Minkowski-core regular black hole wit…
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…
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…
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…
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…
