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

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

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.
Journal ArticleDOI

Binary Black Hole Mergers in the First Advanced LIGO Observing Run

B. P. Abbott, +981 more
- 21 Oct 2016 - 
TL;DR: The first observational run of the Advanced LIGO detectors, from September 12, 2015 to January 19, 2016, saw the first detections of gravitational waves from binary black hole mergers as discussed by the authors.
