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

GW190814: Gravitational Waves from the Coalescence of a 23 M$_\odot$ Black Hole with a 2.6 M$_\odot$ Compact Object

R. Abbott, +1254 more
TL;DR: In this article, the authors reported the observation of a compact binary coalescence involving a 22.2 -24.3 magnitude black hole and a compact object with a mass of 2.50 -2.67 magnitude.
Journal ArticleDOI

Binary Black Hole Mergers in the first Advanced LIGO Observing Run

B. P. Abbott, +972 more
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.
Journal ArticleDOI

A gravitational-wave standard siren measurement of the Hubble constant

B. P. Abbott, +1322 more
- 02 Nov 2017 - 
TL;DR: A measurement of the Hubble constant is reported that combines the distance to the source inferred purely from the gravitational-wave signal with the recession velocity inferred from measurements of the redshift using the electromagnetic data.
Journal ArticleDOI

GW190521: A Binary Black Hole Merger with a Total Mass of 150 M

R. Abbott, +1335 more
TL;DR: It is inferred that the primary black hole mass lies within the gap produced by (pulsational) pair-instability supernova processes, with only a 0.32% probability of being below 65 M⊙, which can be considered an intermediate mass black hole (IMBH).
