Influence of accretion disk on the optical appearance of the Kazakov-Solodukhin black hole
Yu-Xiang Huang, Sen Guo, Yu-Hao Cui +2
The optical characteristics of the Kazakov-Solodukhin (KS) black hole (BH) surrounded by a thin disk is investigated. By utilizing the ray-tracing technique, we derive the the dire…
Influence of dark matter equation of state on the axial gravitational ringing of supermassive black holes
Yuqian Zhao, Bing Sun, Zhoujian Cao +2
In this work, we explore the effects of surrounding dark matter featuring different equations of state on the axial gravitational quasinormal modes of supermassive black holes situ…
Quasinormal modes and echo effect of cylindrical anti-de Sitter black hole spacetime with a thin shell
Kai Lin
This paper investigates the quasinormal mode (QNM) vibrations of a rotating cylindrical black hole (or black string) spacetime that is surrounded by a thin shell rotating synchrono…
Quasinormal Modes by Improved Matrix Method and Weighted Residual Method
Kai Lin
This work discusses the Improved Matrix Method and Weighted Residual Method for studying the quasinormal modes (QNMs) of black holes. In the first method, by utilizing Jordan decom…
The Axial Gravitational Ringing of a Spherically Symmetric Black Hole Surrounded by Dark Matter Spike
Yuqian Zhao, Bing Sun, Kai Lin +1
Supermassive black holes at the center of each galaxy may be surrounded by dark matter. Such dark matter admits a spike structure and vanishes at a certain distance from the black…
Quasinormal Modes for Dynamical Black Holes
Kai Lin, Yang-Yi Sun, Hongsheng Zhang
Realistic black holes are usually dynamical, noticeable or sluggish. The Vaidya metric is a significant and tractable model for simulating a dynamical black hole. In this study, we…
