Spectroscopy of analogue black holes using simulation-based inference
Leonardo Solidoro, Sebastian H. Völkel, Silke Weinfurtner
The emergence of precision gravity simulators in quantum and fluid systems is opening new avenues for probing curved-spacetime physics and black-hole phenomenology under controlled…
Confronting eikonal and post-Kerr methods with numerical evolution of scalar field perturbations in spacetimes beyond Kerr
Ciro De Simone, Sebastian H. Völkel, Kostas D. Kokkotas +2
The accurate computation of quasinormal modes from rotating black holes beyond general relativity is crucial for testing fundamental physics with gravitational waves. In this study…
Combining simulation-based inference and universal relations for precise and accurate neutron star science
Christian J. Krüger, Sebastian H. Völkel
In this work, we propose a novel approach for identifying, constructing, and validating precise and accurate universal relations for neutron star bulk quantities. A central element…
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…
