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

GW170104: Observation of a 50-Solar-Mass Binary Black Hole Coalescence at Redshift 0.2

B. P. Abbott, +1065 more
TL;DR: The magnitude of modifications to the gravitational-wave dispersion relation is constrain, the graviton mass is bound to m_{g}≤7.7×10^{-23} eV/c^{2} and null tests of general relativity are performed, finding that GW170104 is consistent with 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

Characterization of the LIGO detectors during their sixth science run

J. Aasi, +887 more
TL;DR: In this paper, the authors review the performance of the LIGO instruments during this epoch, the work done to characterize the detectors and their data, and the effect that transient and continuous noise artefacts have on the sensitivity of the detectors to a variety of astrophysical sources.
