Cesà ro convergence of the high-order WKB method and its applications to black-hole overtones and long-lived modes
Roman A. Konoplya, Jerzy Matyjasek, Alexander Zhidenko
We develop a fully automatic Mathematica implementation of the black-hole WKB method at very high orders based on the Bender-Wu algorithm, which in principle is limited only by mem…
An efficient higher-order WKB code for quasinormal modes and greybody factors
Roman A. Konoplya, Jerzy Matyjasek, Alexander Zhidenko
The higher-order WKB Mathematica code for computing quasinormal modes, whose accuracy was significantly enhanced through extensions to higher orders and, in particular, through the…
The shadow and quasinormal modes of the asymptotically flat hairy black holes with a dilaton potential
Sheng-Han Xiong, Yong-Zhuang Li, Xiao-Mei Kuang +1
In this article, the shadow and the quasinormal modes (QNMs) of an exact asymptotically flat hairy electrically charged black hole solution with a dilaton potential are investigate…
Quasinormal Modes of Black Holes: Efficient and Highly Accurate Calculations with Recurrence-Based Methods
Kristian Benda, Jerzy Matyjasek
We discuss new recurrence-based methods for calculating the complex frequencies of the quasinormal modes of black holes. These methods are based on the Frobenius series solutions o…
