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 ...

New binary black hole mergers in the LIGO-Virgo O3b data [PDF]

open access: yesPhysical Review D, 2023
We report the detection of 6 new candidate binary black hole (BBH) merger signals in the publicly released data from the second half of the third observing run (O3b) of advanced LIGO and advanced Virgo.

advligorts: The Advanced LIGO real-time digital control and data acquisition system

open access: yesSoftwareX, 2021
The Advanced LIGO detectors are sophisticated opto-mechanical devices. At the core of their operation is feedback control. The Advanced LIGO project developed a custom digital control and data acquisition system to handle the unique needs of this new ...

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

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,
