The Laser Interferometer Gravitational Wave Observatory (LIGO) project [PDF]

open access: yes, 1993
The LIGO (Laser Interferometer Gravitational-Wave Observatory) project is designed to open a new field of science by detecting and studying the gravitational waves from astrophysical sources, including neutron stars, black holes, and possibly, supernovae

GW200105 and GW200115 are compatible with a scenario of primordial black hole binary coalescences

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
Two gravitational wave events, i.e. GW200105 and GW200115, were observed by the Advanced LIGO and Virgo detectors recently. In this work, we show that they can be explained by a scenario of primordial black hole binaries that are formed in the early ...

The updated DESGW processing pipeline for the third LIGO/VIRGO observing run [PDF]

open access: yesEPJ Web of Conferences, 2020
The DESGW group seeks to identify electromagnetic counterparts of gravitational wave events seen by the LIGO-VIRGO network, such as those expected from binary neutron star mergers or neutron star-black hole mergers.

Search for the isotropic stochastic background using data from Advanced LIGO’s second observing run [PDF]

open access: yesPhysical Review D, 2019
The stochastic gravitational-wave background is a superposition of sources that are either too weak or too numerous to detect individually. In this study we present the results from a cross-correlation analysis on data from Advanced LIGO's second ...

Displacement and Vibration Measurements with Interferometers: Benchmark Configurations, Performance, and R&D Opportunities

open access: yesAdvanced Photonics Research, Volume 6, Issue 12, December 2025.
Self‐mixing interferometry is a powerful technique that brings together the exceptional sensitivity of phase measurements with the unequalled simplicity of the self‐mix configuration based on modulation of the cavity field induced by the return from the target. According to the selected measurand, displacement or vibration, and to the analog of digital

Photonic Metrology with Hierarchic Quantum Frequentist Bounds

open access: yesAdvanced Photonics Research, Volume 6, Issue 12, December 2025.
This paper proposes photonic metrology with hierarchical quantum frequentist bounds. The present model tightens the Quantum Cramér‐Rao Bound using a hybrid classical‐quantum framework. The experiment validates the hierarchical frequentist bounds for single‐qubit phase estimation.

BOSS-LDG: A Novel Computational Framework that Brings Together Blue Waters, Open Science Grid, Shifter and the LIGO Data Grid to Accelerate Gravitational Wave Discovery [PDF]

open access: yes, 2017
We present a novel computational framework that connects Blue Waters, the NSF-supported, leadership-class supercomputer operated by NCSA, to the Laser Interferometer Gravitational-Wave Observatory (LIGO) Data Grid via Open Science Grid technology.

Status of LIGO

open access: yesJournal of Physics: Conference Series, 2008
LIGO successfully acquired more than one year of three-way coincident observation data using all three detectors during its fifth science run from November 2005 to the end of September 2007. All detectors reached sensitivity better than the design. For the two 4km detectors, the all-sky averaged detection range exceeded 15 Mpc with a signal-to-noise ...

New binary black hole mergers in the second observing run of Advanced LIGO and Advanced Virgo [PDF]

open access: yesPhysical Review D, 2019
We report the detection of new binary black hole merger events in the publicly available data from the second observing run of advanced LIGO and advanced Virgo (O2). The mergers were discovered using the new search pipeline described in Venumadhav et al.
