Spectral instability in modified Pöschl-Teller effective potential triggered by deterministic and random perturbations
Shui-Fa Shen, Guan-Ru Li, Ramin G. Daghigh +4
Owing to its substantial implications for black hole spectroscopy, spectral instability has attracted considerable attention in the literature. While the emergence of such instabil…
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…
Asymptotic quasinormal modes, echoes, and black hole spectral instability: a brief review
Shui-Fa Shen, Guan-Ru Li, Ramin G. Daghigh +4
We present a short review of the analytical aspects of recent progress in the study of black hole spectral instability and its potential observational consequences. This topic, ins…
An MLE analysis on the relationship between the initial-state granularity and final-state flow factorization
Shui-Fa Shen, Chong Ye, Dan Wen +5
In this study, we employ the maximum likelihood estimator (MLE) to investigate the relationship between initial-state fluctuations and final-state anisotropies in relativistic heav…
