Quasinormal modes of rotating black holes beyond general relativity in the WKB approximation
Ruijing Tang, Nicola Franchini, Sebastian H. Völkel +1
Exploring gravitational theories beyond general relativity (GR) with black hole (BH) spectroscopy requires accurate and flexible methods for computing their quasinormal mode (QNM)…
Black hole spectroscopy of collapsing and merging neutron stars
Oliver Steppohn, Sebastian H. Völkel, Tim Dietrich
Black hole spectroscopy is an important pillar when studying gravitational waves from black holes and enables tests of general relativity. Most of the gravitational-wave signals ob…
Quantifying Systematic Biases in Black Hole Spectroscopy
Sebastian H. Völkel, Arnab Dhani
How long after the merger of two black holes can one rely on linear perturbation theory, and how many quasinormal modes are in the ringdown? Such questions suggest that black hole…
Bayesian analysis of analog gravity systems with the Rezzolla-Zhidenko metric
Saulo Albuquerque, Sebastian H. Völkel
Analog gravity systems have the unique opportunity to probe theoretical aspects of black hole physics in a controlled laboratory environment that one cannot easily observe for astr…
