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…
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…
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…
