Quasinormal modes of black holes and black branes

E Berti, V Cardoso, AO Starinets - Classical and Quantum Gravity, 2009 - iopscience.iop.org
Quasinormal modes are eigenmodes of dissipative systems. Perturbations of classical
gravitational backgrounds involving black holes or branes naturally lead to quasinormal …

Characteristic evolution and matching

J Winicour - Living Reviews in Relativity, 2012 - Springer
I review the development of numerical evolution codes for general relativity based upon the
characteristic initial-value problem. Progress in characteristic evolution is traced from the …

Analysis of ringdown overtones in GW150914

R Cotesta, G Carullo, E Berti, V Cardoso - Physical Review Letters, 2022 - APS
We analyze GW150914 postmerger data to understand if ringdown overtone detection
claims are robust. We find no evidence in favor of an overtone in the data after the waveform …

Agnostic black hole spectroscopy: Quasinormal mode content of numerical relativity waveforms and limits of validity of linear perturbation theory

V Baibhav, MHY Cheung, E Berti, V Cardoso, G Carullo… - Physical Review D, 2023 - APS
Black hole spectroscopy is the program to measure the complex gravitational wave
frequencies of merger remnants, and to quantify their agreement with the characteristic …

Review of summation-by-parts schemes for initial–boundary-value problems

M Svärd, J Nordström - Journal of Computational Physics, 2014 - Elsevier
High-order finite difference methods are efficient, easy to program, scale well in multiple
dimensions and can be modified locally for various reasons (such as shock treatment for …

Extracting linear and nonlinear quasinormal modes from black hole merger simulations

MHY Cheung, E Berti, V Baibhav, R Cotesta - Physical Review D, 2024 - APS
In general relativity, when two black holes merge they produce a rotating (Kerr) black hole
remnant. According to perturbation theory, the remnant emits “ringdown” radiation; a …

Quasinormal-mode filters: A new approach to analyze the gravitational-wave ringdown of binary black-hole mergers

S Ma, K Mitman, L Sun, N Deppe, F Hébert, LE Kidder… - Physical Review D, 2022 - APS
We propose two frequency-domain filters to analyze ringdown signals of binary black hole
mergers. The first rational filter is constructed based on a set of (arbitrary) quasinormal …

Black hole ringdown: the importance of overtones

M Giesler, M Isi, MA Scheel, SA Teukolsky - Physical Review X, 2019 - APS
It is possible to infer the mass and spin of the remnant black hole from binary black hole
mergers by comparing the ringdown gravitational wave signal to results from studies of …

Challenges in quasinormal mode extraction: Perspectives from numerical solutions to the Teukolsky equation

H Zhu, JL Ripley, A Cárdenas-Avendaño, F Pretorius - Physical Review D, 2024 - APS
The intricacies of black hole ringdown analysis are amplified by the absence of a complete
set of orthogonal basis functions for quasinormal modes. Although damped sinusoids …

Inspiral, merger, and ring-down of equal-mass black-hole binaries

A Buonanno, GB Cook, F Pretorius - Physical Review D—Particles, Fields …, 2007 - APS
We investigate the dynamics and gravitational-wave (GW) emission in the binary merger of
equal-mass black holes as obtained from numerical relativity simulations. The simulations …
