Broadband Quantum Enhancement of the LIGO Detectors with Frequency-Dependent Squeezing

open access: yesPhysical Review X, 2023
Quantum noise imposes a fundamental limitation on the sensitivity of interferometric gravitational-wave detectors like LIGO, manifesting as shot noise and quantum radiation pressure noise.

Deep Einstein@Home All-sky Search for Continuous Gravitational Waves in LIGO O3 Public Data [PDF]

open access: yesThe Astrophysical Journal, 2023
We present the results of an all-sky search for continuous gravitational waves in the public LIGO O3 data. The search covers signal frequencies 20.0 Hz ≤ f ≤ 800.0 Hz and a spin-down range down to −2.6 × 10 ^−9 Hz s ^−1 , motivated by detectability ...

Subtracting glitches from gravitational-wave detector data during the third LIGO-Virgo observing run [PDF]

open access: greenClassical and quantum gravity, 2022
Data from ground-based gravitational-wave detectors contains numerous short-duration instrumental artifacts, called ‘glitches’. The high rate of these artifacts in turn results in a significant fraction of gravitational-wave signals from compact binary ...

Search for gravitational-lensing signatures in the full third observing run of the LIGO–Virgo network [PDF]

open access: greenAstrophysical Journal, 2023
Gravitational lensing by massive objects along the line of sight to the source causes distortions to gravitational wave (GW) signals; such distortions may reveal information about fundamental physics, cosmology, and astrophysics.

Primordial black holes confront LIGO/Virgo data: current situation [PDF]

open access: greenJournal of Cosmology and Astroparticle Physics, 2020
The LIGO and Virgo Interferometers have so far provided 11 gravitational-wave (GW) observations of black-hole binaries. Similar detections are bound to become very frequent in the near future.

Binary Black Hole Population Properties Inferred from the First and Second Observing Runs of Advanced LIGO and Advanced Virgo [PDF]

open access: greenAstrophysical Journal, 2019
We present results on the mass, spin, and redshift distributions with phenomenological population models using the 10 binary black hole (BBH) mergers detected in the first and second observing runs completed by Advanced LIGO and Advanced Virgo.

open access: yesPhysical Review D, 2021
The second Gravitational-Wave Transient Catalog reported on 39 compact binary coalescences observed by the Advanced LIGO and Advanced Virgo detectors between 1 April 2019 15:00 UTC and 1 October 2019 15:00 UTC.

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.

Search for Eccentric Black Hole Coalescences during the Third Observing Run of LIGO and Virgo [PDF]

open access: yesAstrophysical Journal, 2023
Despite the growing number of binary black hole coalescences confidently observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain.
