Evolving extreme mass-ratio inspirals in a perturbed Schwarzschild spacetime
Michael LaHaye, Colin Weller, Dongjun Li +3
In this work, we develop the modified Teukolsky formalism that describes the GW radiation from a point mass orbiting around a perturbed Schwarzschild BH. This perturbation of the b…
Extreme mass-ratio inspiral within an ultralight scalar cloud I. Scalar radiation
Dongjun Li, Colin Weller, Patrick Bourg +3
In this work, we study the dynamics of an extreme mass-ratio inspiral (EMRI) embedded within a scalar cloud populated around the massive black hole. This cloud may be generated thr…
The ringdown of a black hole surrounded by a thin shell of matter
Andrew Laeuger, Colin Weller, Dongjun Li +1
Recent studies have shown that far-field perturbations to the curvature potential of a black hole spacetime may destabilize its quasinormal mode (QNM) spectrum while only mildly af…
Perturbations of spinning black holes in dynamical Chern-Simons gravity: Slow rotation quasinormal modes
Dongjun Li, Pratik Wagle, Yanbei Chen +1
Gravitational waves offer new ways to test general relativity (GR) in the strong-field regime, including tests involving the ringdown phase of binary black hole mergers, characteri…
