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)…

Asymptotical quasinormal mode spectrum for piecewise approximate effective potential
Wei-Liang Qian, Kai Lin, Cai-Ying Shao +2
It was pointed out that the black hole quasinormal modes resulting from a piecewise approximate potential are drastically distinct from those pertaining to the original black hole…
