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 (HeunD) method that extends our construction of complete quasinormal-mode (QNM) spectra to extremal Kerr black holes. Matching the horizon-ingoin…
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…
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…
A high-order compact finite difference scheme and precise integration method based on modified Hopf-Cole transformation for numerical simulation of n-dimensional Burgers' system
Changkai Chen, Xiaohua Zhang, Zhang Liu
This paper modifies a n-dimensional Hopf-Cole transformation to the n-dimensional Burgers' system. We obtain the n-dimensional heat conduction equation through the modification of…
