Probing Dark Matter with Gravitational Waves: Spin-Modulated Dephasing from Black Holes in Halos
Guoyang Fu, Yunqi Liu, Jian-Pin Wu +2
We develop a novel analytical framework for constructing axisymmetric black hole spacetimes sourced by dark matter (DM) halos. Applying this to extreme mass ratio inspirals (EMRIs)…
Black Holes Trapped by Ghosts
Cheng-Yong Zhang, Yunqi Liu, Bin Wang
Violent cosmic events, from black hole mergers to stellar collapses, often leave behind highly excited black hole remnants that inevitably relax to equilibrium. The prevailing view…
Non-linearly scalarized supermassive black holes
Shoupan Liu, Yunqi Liu, Yan Peng +1
In this study, we investigate a nonlinear mechanism driving the formation of scalarized rotating black holes within a scalar-Gauss-Bonnet gravity framework that includes an additio…
Rotating scalarized supermassive black holes
Shoupan Liu, Yunqi Liu, Yan Peng +1
In this study, we investigate rotating black hole solutions within a scalar Gauss-Bonnet gravity framework that incorporates a squared Gauss-Bonnet term. By employing a quadratic e…
Probing Quantum Gravity Effects with Eccentric Extreme Mass-Ratio Inspirals
Guoyang Fu, Yunqi Liu, Bin Wang +2
In this paper, we investigate the impact of loop quantum gravity (LQG) on extreme mass-ratio inspirals (EMRIs), and the results indicate that LQG effects cause the orbital decay to…
