Confronting general relativity with principal component analysis: Simulations and results from GWTC-3 events Open
We present a comprehensive assessment of multiparameter tests of general relativity (GR) in the inspiral regime of compact binary coalescences using principal component analysis (PCA). Our analysis is based on an extensive set of simulated…

Eccentricity Estimation for Five Binary Black Hole Mergers with Higher-order Gravitational-wave Modes Open
The detection of orbital eccentricity for a binary black hole system via gravitational waves is a key signature to distinguish between the possible binary origins. The identification of eccentricity has been difficult so far due to the lim…

Accuracy limitations of existing numerical relativity waveforms on the data analysis of current and future ground-based detectors Open
As gravitational wave detectors improve in sensitivity, signal-to-noise ratios of compact binary coalescences will dramatically increase, reaching values in the hundreds and potentially thousands. Such strong signals offer both exciting sc…

Waveform Modelling for the Laser Interferometer Space Antenna Open
LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will expand our view to the millihertz gravitational-wave sky, wher…

Gravitational recoil from binary black hole mergers in scalar field clouds Open
In vacuum, the gravitational recoil of the final black hole from the merger of two black holes depends exclusively on the mass ratio and spins of the coalescing black holes, and on the eccentricity of the binary. If matter is present, accr…

Post-merger chirps from binary black holes as probes of the final black-hole horizon Open
The merger of a binary black hole gives birth to a highly distorted final black hole. The gravitational radiation emitted as this black hole relaxes presents us with the unique opportunity to probe extreme gravity and its connection with t…

Measuring Spin of the Remnant Black Hole from Maximum Amplitude Open
Gravitational waves emitted during the merger of two black holes carry information about the remnant black hole, namely its mass and spin. This information is typically found from the ringdown radiation as the black hole settles to a final…

Coping with spurious radiation in binary black hole simulations Open
Spurious junk radiation in the initial data for binary black hole numerical simulations has been an issue of concern. The radiation affects the masses and spins of the black holes, modifying their orbital dynamics and thus potentially comp…

Tracking Black Hole Kicks from Gravitational-Wave Observations Open
Coalescing binary black holes emit anisotropic gravitational radiation. This causes a net emission of linear momentum that produces a gradual acceleration of the source. As a result, the final remnant black hole acquires a characteristic v…
