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…
