Intrinsic handedness in O1-O4a black-hole mergers: probing orbital precession, remnant retention in dense environments and cosmological mirror asymmetry
Juan Calderón Bustillo, Adrián del Rio, Nicolás Sanchis-Gual +1
Precessing binary black-holes generically produce an imbalance of right- and left- handed gravitational waves, reflecting the breaking of mirror symmetry by the merger dynamics. We…
Convolutional Neural Networks for the classification of glitches in gravitational-wave data streams
Tiago S. Fernandes, Samuel J. Vieira, Antonio Onofre +3
We investigate the use of Convolutional Neural Networks (including the modern ConvNeXt network family) to classify transient noise signals (i.e.~glitches) and gravitational waves i…
GW190521: A Binary Black Hole Merger with a Total Mass of
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1253
On May 21, 2019 at 03:02:29 UTC Advanced LIGO and Advanced Virgo observed a short duration gravitational-wave signal, GW190521, with a three-detector network signal-to-noise ratio…
Mapping the Universe Expansion: Enabling percent-level measurements of the Hubble Constant with a single binary neutron-star merger detection
Juan Calderón Bustillo, Samson H. W. Leong, Tim Dietrich +1
The joint observation of the gravitational-wave and electromagnetic signal from the binary neutron-star merger GW170817 allowed for a new independent measurement of the Hubble cons…
Measuring Spin of the Remnant Black Hole from Maximum Amplitude
Deborah Ferguson, Sudarshan Ghonge, James A. Clark +3
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…
Tracking black hole kicks from gravitational wave observations
Juan Calderón Bustillo, James A. Clark, Pablo Laguna +1
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 resul…
A Search for Tensor, Vector, and Scalar Polarizations in the Stochastic Gravitational-Wave Background
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1097
The detection of gravitational waves with Advanced LIGO and Advanced Virgo has enabled novel tests of general relativity, including direct study of the polarization of gravitationa…
GW170814: A Three-Detector Observation of Gravitational Waves from a Binary Black Hole Coalescence
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1107
On August 14, 2017 at 10:30:43 UTC, the Advanced Virgo detector and the two Advanced LIGO detectors coherently observed a transient gravitational-wave signal produced by the coales…
