Complete quasinormal modes of Type-D black holes. II. Extremal Kerr black holes

Changkai Chen, Xiaohua Zhang, Zhoujian Cao +1

We develop a double-confluent Heun method that extends our previous study of complete quasinormal-mode (QNM) spectra of Type-D black holes to extremal Kerr black holes. Radial boun…

Efficient and stable computation of gravitational-wave fluxes from generic Kerr orbits via a unified Heun-function 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…
