Jia W, Yamamoto H, Kuns K, Effler A, Evans M, Fritschel P, et al.
Phys Rev Lett . 2021 Dec; 127(24):241102. PMID: 34951783
High-quality optical resonant cavities require low optical loss, typically on the scale of parts per million. However, unintended micron-scale contaminants on the resonator mirrors that absorb the light circulating in...

Whittle C, Hall E, Dwyer S, Mavalvala N, Sudhir V, Abbott R, et al.
Science . 2021 Jun; 372(6548):1333-1336. PMID: 34140386
The motion of a mechanical object, even a human-sized object, should be governed by the rules of quantum mechanics. Coaxing them into a quantum state is, however, difficult because the...

Brooks A, Vajente G, Yamamoto H, Abbott R, Adams C, Adhikari R, et al.
Appl Opt . 2021 May; 60(13):4047-4063. PMID: 33983346
Small, highly absorbing points are randomly present on the surfaces of the main interferometer optics in Advanced LIGO. The resulting nanometer scale thermo-elastic deformations and substrate lenses from these micron-scale...

Abbott B, Abbott R, Abbott T, Abraham S, Acernese F, Ackley K, et al.
Living Rev Relativ . 2020 Oct; 23(1):3. PMID: 33015351
We present our current best estimate of the plausible observing scenarios for the Advanced LIGO, Advanced Virgo and KAGRA gravitational-wave detectors over the next several years, with the intention of...

Abbott R, Abbott T, Abraham S, Acernese F, Ackley K, Adams C, et al.
Phys Rev Lett . 2020 Sep; 125(10):101102. PMID: 32955328
On May 21, 2019 at 03:02:29 UTC Advanced LIGO and Advanced Virgo observed a short duration gravitational-wave signal, GW190521, with a three-detector network signal-to-noise ratio of 14.7, and an estimated...

Abbott B, Abbott R, Abbott T, Abernathy M, Acernese F, Ackley K, et al.
Class Quantum Gravity . 2020 Sep; 33(13). PMID: 32908328
On September 14, 2015, a gravitational wave signal from a coalescing black hole binary system was observed by the Advanced LIGO detectors. This paper describes the transient noise backgrounds used...

Abbott B, Abbott R, Abbott T, Abernathy M, Acernese F, Ackley K, et al.
Phys Rev D . 2020 Aug; 93(12). PMID: 32818163
On September 14, 2015 at 09:50:45 UTC the two detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO) simultaneously observed the binary black hole merger GW150914. We report the results of...

Abbott B, Abbott R, Abbott T, Abraham S, Acernese F, Ackley K, et al.
Phys Rev Lett . 2019 Nov; 123(16):161102. PMID: 31702344
We present a search for subsolar mass ultracompact objects in data obtained during Advanced LIGO's second observing run. In contrast to a previous search of Advanced LIGO data from the...

Abbott B, Abbott R, Abbott T, Acernese F, Ackley K, Adams C, et al.
Phys Rev Lett . 2019 Aug; 123(1):011102. PMID: 31386391
The recent discovery by Advanced LIGO and Advanced Virgo of a gravitational wave signal from a binary neutron star inspiral has enabled tests of general relativity (GR) with this new...

Abbott B, Abbott R, Abbott T, Acernese F, Ackley K, Adams C, et al.
Phys Rev Lett . 2019 Mar; 122(6):061104. PMID: 30822067
We analyze the impact of a proposed tidal instability coupling p modes and g modes within neutron stars on GW170817. This nonresonant instability transfers energy from the orbit of the...
