Two populations of LIGO-Virgo black holes [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2020
We analyse the LIGO-Virgo data, including the recently released GWTC-2dataset, to test a hypothesis that the data contains more than one population of black holes.

Data-driven Expectations for Electromagnetic Counterpart Searches Based on LIGO/Virgo Public Alerts [PDF]

open access: yesAstrophysical Journal, 2021
Searches for electromagnetic counterparts of gravitational-wave signals have redoubled since the first detection in 2017 of a binary neutron star merger with a gamma-ray burst, optical/infrared kilonova, and panchromatic afterglow.

Characterization of thermal effects in the Enhanced LIGO Input Optics [PDF]

open access: yes, 2011
We present the design and performance of the LIGO Input Optics subsystem as implemented for the sixth science run of the LIGO interferometers. The Initial LIGO Input Optics experienced thermal side effects when operating with 7 W input power. We designed,

Prospects for Stochastic Background Searches Using Virgo and LSC Interferometers [PDF]

open access: yes, 2007
We consider the question of cross-correlation measurements using Virgo and the LSC Interferometers (LIGO Livingston, LIGO Hanford, and GEO600) to search for a stochastic gravitational-wave background. We find that inclusion of Virgo into the network will

Advanced LIGO detector performance in the fourth observing run [PDF]

open access: yesPhysical Review D
On May 24th, 2023, the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO), joined by the Advanced Virgo and KAGRA detectors, began the fourth observing run for a two-year-long dedicated search for gravitational waves.

Binary Black Hole Mergers in the First Advanced LIGO Observing Run [PDF]

open access: yes, 2016
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.

All-sky search for continuous gravitational waves from isolated neutron stars using Advanced LIGO and Advanced Virgo O3 data [PDF]

open access: yesPhysical Review D, 2022
We present results of an all-sky search for continuous gravitational waves which can be produced by spinning neutron stars with an asymmetry around their rotation axis, using data from the third observing run of the Advanced LIGO and Advanced Virgo ...

Silica suspension and coating developments for Advanced LIGO [PDF]

open access: yes, 2006
The proposed upgrade to the LIGO detectors to form the Advanced LIGO detector system is intended to incorporate a low thermal noise monolithic fused silica final stage test mass suspension based on developments of the GEO 600 suspension design. This will

The Electromagnetic Counterpart of the Binary Neutron Star Merger LIGO/Virgo GW170817. II. UV, Optical, and Near-infrared Light Curves and Comparison to Kilonova Models [PDF]

open access: yes, 2017
We present UV, optical, and near-infrared (NIR) photometry of the first electromagnetic counterpart to a gravitational wave source from Advanced Laser Interferometer Gravitational-wave Observatory (LIGO)/Virgo, the binary neutron star merger GW170817 ...

Matched filtering of gravitational waves from inspiraling compact binaries: Computational cost and template placement [PDF]

open access: yes, 1998
We estimate the number of templates, computational power, and storage required for a one-step matched filtering search for gravitational waves from inspiraling compact binaries.
