New binary black hole mergers in the LIGO-Virgo O3a data [PDF]

open access: yesPhysical Review D, 2022
We report the detection of ten new binary black hole (BBH) mergers in the publicly released data from the the first half of the third observing run (O3a) of advanced LIGO and advanced Virgo.

LIGO detector characterization in the second and third observing runs [PDF]

open access: yesClassical and quantum gravity, 2021
The characterization of the Advanced LIGO detectors in the second and third observing runs has increased the sensitivity of the instruments, allowing for a higher number of detectable gravitational-wave signals, and provided confirmation of all observed ...

Population Properties of Compact Objects from the Second LIGO–Virgo Gravitational-Wave Transient Catalog [PDF]

open access: yes, 2020
We report on the population of 47 compact binary mergers detected with a false-alarm rate of < 1yr−1 in the second LIGO–Virgo Gravitational-Wave Transient Catalog.

Bayesian inference for compact binary coalescences with bilby: validation and application to the first LIGO–Virgo gravitational-wave transient catalogue [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2020
Gravitational waves provide a unique tool for observational astronomy. While the first LIGO–Virgo catalogue of gravitational-wave transients (GWTC-1) contains 11 signals from black hole and neutron star binaries, the number of observations is ...

Constraints on Cosmic Strings Using Data from the Third Advanced LIGO-Virgo Observing Run. [PDF]

open access: yesPhysical Review Letters, 2021
We search for gravitational-wave signals produced by cosmic strings in the Advanced LIGO and Virgo full O3 dataset. Search results are presented for gravitational waves produced by cosmic string loop features such as cusps, kinks, and, for the first time,

Tests of General Relativity with Binary Black Holes from the second LIGO-Virgo Gravitational-Wave Transient Catalog [PDF]

open access: yes, 2020
Gravitational waves enable tests of general relativity in the highly dynamical and strong-field regime. Using events detected by LIGO-Virgo up to 1 October 2019, we evaluate the consistency of the data with predictions from the theory. We first establish

Inference-Optimized AI and High Performance Computing for Gravitational Wave Detection at Scale

open access: yesFrontiers in Artificial Intelligence, 2022
We introduce an ensemble of artificial intelligence models for gravitational wave detection that we trained in the Summit supercomputer using 32 nodes, equivalent to 192 NVIDIA V100 GPUs, within 2 h.

Dependence of the detected signal on the kinematic parameters of the satellite in the S-LIGO-E2R space system

open access: yesDoklady Belorusskogo gosudarstvennogo universiteta informatiki i radioèlektroniki, 2021
The changes of distances less than ~10–21 are registered during the gravitational wave experiment. This feature determines the minimum size of experimental installations and the frequency range of gravitational wave detectors.

LIGO: the Laser Interferometer Gravitational-Wave Observatory [PDF]

open access: bronze2006 Conference on Lasers and Electro-Optics and 2006 Quantum Electronics and Laser Science Conference, 2009
LIGO is a trio of extremely sensitive Michelson interferometers built to detect gravitational waves from space. We describe predicted sources of gravitational waves, our detectors, and the results of our recent observations.

GWTC-1: A Gravitational-Wave Transient Catalog of Compact Binary Mergers Observed by LIGO and Virgo during the First and Second Observing Runs [PDF]

open access: yes, 2018
We present the results from three gravitational-wave searches for coalescing compact binaries with component masses above 1$\mathrm{M}_\odot$ during the first and second observing runs of the Advanced gravitational-wave detector network. During the first
