LIGO: the Laser Interferometer Gravitational-Wave Observatory
- B. Abbott, R. Abbott, J. Zweizig
- PhysicsScience
- 17 April 1992
The goal of the Laser Interferometric Gravitational-Wave Observatory (LIGO) is to detect and study gravitational waves (GWs) of astrophysical origin. Direct detection of GWs holds the promise of…
Multi-messenger Observations of a Binary Neutron Star Merger

- 26 October 2019
On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced…
An upper limit on the stochastic gravitational-wave background of cosmological origin
- B. Abbott, R. Abbott, J. Rollins
- PhysicsNature
- 20 August 2009
A stochastic background of gravitational waves is expected to arise from a superposition of a large number of unresolved gravitational-wave sources of astrophysical and cosmological origin. It should…
Observing gravitational-wave transient GW150914 with minimal assumptions
- B. Abbott, G. Cagnoli, F. Bondu
- Physics
- 7 June 2016
The gravitational-wave signal GW150914 was first identified on Sept 14 2015 by searches for short-duration gravitational-wave transients. These searches identify time-correlated transients in…
Searches for periodic gravitational waves from unknown isolated sources and Scorpius X-1: Results from the second LIGO science run
- B. Abbott, R. Abbott, J. Zweizig
- Physics
- 25 April 2006
We carry out two searches for periodic gravitational waves using the most sensitive few hours of data from the second LIGO science run. Both searches exploit fully coherent matched filtering and…

The Advanced LIGO gravitational wave detectors are second generation instruments designed and built for the two LIGO observatories in Hanford, WA and Livingston, LA. The two instruments are identical…

Search for gravitational waves from low mass compact binary coalescence in 186 days of LIGO's fifth science run
- B. Abbott, R. Abbott, J. Zweizig
- Physics
- 1 August 2009
We report on a search for gravitational waves from coalescing compact binaries, of total mass between 2 and 35M⊙, using LIGO observations between November 14, 2006 and May 18, 2007. No…
Implications for the Origin of GRB 070201 from LIGO Observations
We analyzed the available LIGO data coincident with GRB 070201, a short-duration, hard-spectrum γ-ray burst (GRB) whose electromagnetically determined sky position is coincident with the spiral arms…
Analysis of LIGO data for gravitational waves from binary neutron stars
We report on a search for gravitational waves from coalescing compact binary systems in the Milky Way and the Magellanic Clouds. The analysis uses data taken by two of the three LIGO interferometers…
