Bound States of the Schwarzschild Black Hole
Sebastian H. Völkel
Understanding the physical significance and spectral stability of black hole quasinormal modes is fundamental to high-precision spectroscopy with future gravitational wave detector…
Higher-derivative corrections to the Kerr quasinormal mode spectrum
Pablo A. Cano, Lodovico Capuano, Nicola Franchini +2
We provide the most complete analysis so far of quasinormal modes of rotating black holes in a general higher-derivative extension of Einstein's theory. By finding the corrections…
Testing General Relativity with Black Hole Quasi-Normal Modes
Nicola Franchini, Sebastian H. Völkel
The purpose of this chapter is to provide an overview of the exciting field of black hole quasi-normal modes and its capabilities to test general relativity in the 21st century. Af…
Theory-agnostic Reconstruction of Potential and Couplings from Quasi-Normal Modes
Sebastian H. Völkel, Nicola Franchini, Enrico Barausse
In this work, we use a parametrized theory-agnostic approach that connects the observation of black hole quasi-normal modes with the underlying perturbation equations, with the goa…
A Semi-analytic Study of Axial Perturbations of Ultra Compact Stars
Sebastian H. Völkel, Kostas D. Kokkotas
Compact object perturbations, at linear order, often lead in solving one or more coupled wave equations. The study of these equations was typically done by numerical or semi-analyt…
