QNM families: classification and competition
Zhen-Hao Yang, Liang-Bi Wu, Xiao-Mei Kuang +1
The perturbation spectra of black holes beyond standard vacuum black hole solutions within generalrelativity (GR) may exhibit complex structures with long-lived modes. This usually…
Gravitational odd-parity perturbation of a Horndeski hairy black hole: quasinormal mode and parameter constraint
Zhen-Hao Yang, Yun-He Lei, Xiao-Mei Kuang +1
During the binary black hole coalescence, gravitational waves emitted at the ringdown stage can be well described by black hole perturbation theory, where the quasinormal modes (QN…
Scalar field perturbation around a rotating hairy black hole: quasinormal modes, quasibound states and superradiant instability
Yun-He Lei, Zhen-Hao Yang, Xiao-Mei Kuang
We consider the quasinormal modes, quasibound states and superradiant instability of a rotating hairy black hole, which possesses a Horndeski hair as deviation from Kerr black hole…
Perturbations of massless external fields in Horndeski hairy black hole
Zhen-Hao Yang, Yun-He Lei, Xiao-Mei Kuang +1
In this paper, we study the propagations of external fields in Horndeski theory, including the scalar field, electromagnetic field and Dirac field. We extensively explore the quasi…
