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…
Images of Braneworld black holes with radiatively inefficient accretion flows
Chengjia Chen, Yin Hao, Zelin Zhang +2
Horizon-scale imaging acts as a transformative tool for probing spacetime geometry, enabling stringent tests of gravitational theories in the strong-field regime. The Casadio-Fabbr…
Quasinormal modes and AdS/CFT correspondence of a rotating BTZ-like black hole in the Einstein-bumblebee gravity
Fangli Quan, Zhong-Wu Xia, Rui Ding +2
We obtain exact expressions for the quasinormal modes (QNMs) of the massive scalar, fermionic and vector perturbations around a rotating BTZ-like black hole in the Einstein-bumbleb…
Charged scalar and Dirac perturbations on a global monopole Reissner-Nordström-de Sitter black hole: quasinormal modes and strong cosmic censorship
Peiyang Li, Mengjie Wang, Jiliang Jing
We study perturbations of charged scalar and Dirac fields around Reissner-Nordström-de Sitter black holes with a global monopole. To this end, we first derive the equations of mot…
Charged Dirac perturbations on Reissner-Nordström black holes in a cavity: quasinormal modes with Robin boundary conditions
Jia Liu, Mengjie Wang, Zishuo Wang +3
We investigate charged Dirac quasinormal spectra on Reissner-Nordström black holes in a mirror-like cavity. For this purpose, we first derive charged Dirac equations, and \textit{…
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…
