GW170817: observation of gravitational waves from a binary neutron star inspiral

B. P. Abbott, +1134 more
TL;DR: The association of GRB 170817A, detected by Fermi-GBM 1.7 s after the coalescence, corroborates the hypothesis of a neutron star merger and provides the first direct evidence of a link between these mergers and short γ-ray bursts.
Journal ArticleDOI

GW151226: observation of gravitational waves from a 22-solar-mass binary black hole coalescence

B. P. Abbott, +973 more
TL;DR: This second gravitational-wave observation provides improved constraints on stellar populations and on deviations from general relativity.
Journal ArticleDOI

Gravitational Waves and Gamma-Rays from a Binary Neutron Star Merger: GW170817 and GRB 170817A

B. P. Abbott, +1198 more
TL;DR: In this paper, the authors used the observed time delay of $(+1.74\pm 0.05)\,{\rm{s}}$ between GRB 170817A and GW170817 to constrain the difference between the speed of gravity and speed of light to be between $-3
Journal ArticleDOI

GW170814: A three-detector observation of gravitational waves from a binary black hole coalescence

B. P. Abbott, +1116 more
TL;DR: For the first time, the nature of gravitational-wave polarizations from the antenna response of the LIGO-Virgo network is tested, thus enabling a new class of phenomenological tests of gravity.
Journal ArticleDOI

GW190425: Observation of a Compact Binary Coalescence with Total Mass ∼ 3.4 M O

B. P. Abbott, +1274 more
TL;DR: In 2019, the LIGO Livingston detector observed a compact binary coalescence with signal-to-noise ratio 12.9 and the Virgo detector was also taking data that did not contribute to detection due to a low SINR but were used for subsequent parameter estimation as discussed by the authors.
