Efficient and Stable Computation of Gravitational-Wave Fluxes from Generic Kerr Orbits via a Unified HeunC Framework
Changkai Chen, Zhoujian Cao, Jiliang Jing
Modeling extreme-mass-ratio inspirals hinges on the accurate and efficient computation of gravitational-wave fluxes from generic Kerr orbits. Conventional frequency-domain techniqu…

Complete quasinormal modes of Type-D black holes
Changkai Chen, Jiliang Jing, Zhoujian Cao +1
Quasinormal mode (QNM) spectra of black holes exhibit two open problems [Conf. Proc. C 0405132, 145 (2004); CQG 26, 163001 (2009)]: (i) the discontinuity in highly damped QNMs betw…

Gravitational wave fluxes on generic orbits in near-extreme Kerr spacetime: higher spin and large eccentricity
Changkai Chen, Jiliang Jing
To obtain the waveform template of gravitational waves (GWs), substantial computational resources and exceedingly high precision are often required. In the previous study [JCAP 11…
