Mixing of spherical and spheroidal modes in perturbed Kerr black holes
Emanuele Berti, Antoine Klein
The angular dependence of the gravitational radiation emitted in compact binary mergers and gravitational collapse is usually separated using spin-weighted spherical harmonics ${}_…
Fast Frequency-domain Waveforms for Spin-Precessing Binary Inspirals
Antoine Klein, Neil Cornish, Nicolás Yunes
The detection and characterization of gravitational wave signals from compact binary coalescence events relies on accurate waveform templates in the frequency domain. The stationar…
Projected Constraints on Scalarization with Gravitational Waves from Neutron Star Binaries
Laura Sampson, Nicolas Yunes, Neil Cornish +5
Certain scalar-tensor theories have the property of endowing stars with scalar hair, sourced either by the star's own compactness (spontaneous scalarization) or, for binary systems…
Detection and Parameter Estimation of Gravitational Waves from Compact Binary Inspirals with Analytical Double-Precessing Templates
Katerina Chatziioannou, Neil Cornish, Antoine Klein +1
We study the performance of various analytical frequency-domain templates for detection and parameter estimation of gravitational waves from spin-precessing, quasi-circular, compac…
Spin-Precession: Breaking the Black Hole--Neutron Star Degeneracy
Katerina Chatziioannou, Neil Cornish, Antoine Klein +1
Mergers of compact stellar remnant are prime targets for the LIGO/Virgo gravitational wave detectors. One hopes that the gravitational wave signals from these merger events can be…
