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…
Open data from the first and second observing runs of Advanced LIGO and Advanced Virgo
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1245
Advanced LIGO and Advanced Virgo are actively monitoring the sky and collecting gravitational-wave strain data with sufficient sensitivity to detect signals routinely. In this pape…
Gravitational waveforms of binary neutron star inspirals using post-Newtonian tidal splicing
Kevin Barkett, Yanbei Chen, Mark A. Scheel +1
The tidal deformations of neutron stars within an inspiraling compact binary alter the orbital dynamics, imprinting a signature on the gravitational wave signal. Modeling this sign…
Spectral Cauchy-characteristic extraction of the gravitational wave news function
Kevin Barkett, Jordan Moxon, Mark A. Scheel +1
We present an improved spectral algorithm for Cauchy-characteristic extraction and characteristic evolution of gravitational waves in numerical relativity. The new algorithms impro…
A guide to LIGO-Virgo detector noise and extraction of transient gravitational-wave signals
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1135
The LIGO Scientific Collaboration and the Virgo Collaboration have cataloged eleven confidently detected gravitational-wave events during the first two observing runs of the advanc…
Model comparison from LIGO-Virgo data on GW170817's binary components and consequences for the merger remnant
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1191
GW170817 is the very first observation of gravitational waves originating from the coalescence of two compact objects in the mass range of neutron stars, accompanied by electromagn…
