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)…

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…

Generic effective sources for first-order in mass-ratio gravitational self-force calculations in Schwarzschild spacetime

Chao Zhang, Rong-gen Cai, Guoyang Fu +3

The numerical calculation of gravitational self-force in extreme mass ratio inspiral systems is fundamentally challenging due to the singular nature of point-particle sources. To o…

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…

The constraint on modified black holes with extreme mass ratio inspirals

Chao Zhang, Guoyang Fu, Yungui Gong

The low-energy effective action of String Theory introduces corrections to the dilaton-graviton sector, resulting in deformed black holes beyond general relativity. We analyze extr…
