Quasinormal frequencies and greybody factors for axial perturbations of dilaton-Euler-Heisenberg de Sitter black holes
Ming Zhang, Guo-Xin Chen, Xufen Zhang +4
We investigate the quasinormal modes (QNMs) and greybody factors of dilaton-Euler-Heisenberg (dEH) de Sitter (dS) black holes in string-inspired Euler-Heisenberg gravity. Since the…
On the mapping between bound states and black hole quasinormal modes via analytic continuation: a spectral instability perspective
Guan-Ru Li, Wei-Liang Qian, Xiao-Mei Kuang +5
In this work, we investigate the relation between bound states and quasinormal modes within black hole perturbation theory in the context of spectral instability. Our analysis indi…
Perturbations of massless external fields on magnetically charged black holes in string-inspired Euler-Heisenberg theory
Xufen Zhang, De-Cheng Zou, Chao-Ming Zhang +2
In this paper, we study the perturbations of massless scalar and electromagnetic fields on the magnetically charged black holes in string-inspired Euler-Heisenberg theory. We calcu…
On Hyperboloidal Foliations in the Study of Black Hole Quasinormal Modes
Shui-Fa Shen, Guan-Ru Li, Xiao-Mei Kuang +5
In this work, we demonstrate that the hyperboloidal foliation technique, applied to the study of black hole quasinormal modes, where the spatial boundary is shifted from spacelike…
