Journal ArticleDOI

Observation of Gravitational Waves from a Binary Black Hole Merger

B. P. Abbott, +1011 more
TL;DR: This is the first direct detection of gravitational waves and the first observation of a binary black hole merger, and these observations demonstrate the existence of binary stellar-mass black hole systems.
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

Tests of general relativity with GW150914

B. P. Abbott, +979 more
TL;DR: It is found that the final remnant's mass and spin, as determined from the low-frequency and high-frequency phases of the signal, are mutually consistent with the binary black-hole solution in general relativity.
Journal ArticleDOI

GW170608: Observation of a 19 solar-mass binary black hole coalescence

B. P. Abbott, +1154 more
TL;DR: In this article, a GW signal from the merger of two stellar-mass black holes was observed by the two Advanced Laser Interferometer Gravitational-Wave Observatory detectors with a network signal-to-noise ratio of 13.5%.
