pygwb: A Python-based Library for Gravitational-wave Background Searches

open access: yesThe Astrophysical Journal, 2023
The collection of gravitational waves (GWs) that are either too weak or too numerous to be individually resolved is commonly referred to as the gravitational-wave background (GWB).

Review of the Advanced LIGO Gravitational Wave Observatories Leading to Observing Run Four

open access: yesGalaxies, 2022
Gravitational waves from binary black hole and neutron star mergers are being regularly detected. As of 2021, 90 confident gravitational wave detections have been made by the LIGO and Virgo detectors.

Searches for continuous-wave gravitational radiation

open access: yesLiving Reviews in Relativity, 2023
Now that detection of gravitational-wave signals from the coalescence of extra-galactic compact binary star mergers has become nearly routine, it is intriguing to consider other potential gravitational-wave signatures.

Scope Out Multiband Gravitational-Wave Observations of GW190521-Like Binary Black Holes with Space Gravitational Wave Antenna B-DECIGO

open access: yesUniverse, 2021
The gravitational wave event, GW190521, is the most massive binary black hole merger observed by ground-based gravitational wave observatories LIGO/Virgo to date.

A joint search for gravitational wave bursts with AURIGA and LIGO [PDF]

open access: yes, 2008
The first simultaneous operation of the AURIGA detector* and the LIGO observatory* was an opportunity to explore real data, joint analysis methods between two very different types of gravitational wave detectors: resonant bars and interferometers.

Gravitational Waves from a Core-Collapse Supernova: Perspectives with Detectors in the Late 2020s and Early 2030s

open access: yesGalaxies, 2022
We studied the detectability and reconstruction of gravitational waves from core-collapse supernova multidimensional models using simulated data from detectors predicted to operate in the late 2020s and early 2030s. We found that the detection range will

Observation of a kilogram-scale oscillator near its quantum ground state [PDF]

open access: yes, 2009
We introduce a novel cooling technique capable of approaching the quantum ground state of a kilogram-scale system—an interferometric gravitational wave detector.

A Search for Gravitational Waves from Perturbed Black Hole Ringdowns in LIGO Data [PDF]

open access: yes, 2008
According to General Relativity a perturbed black hole will return to a stable configuration by the emission of gravitational radiation in a superposition of quasi-normal modes. Such a perturbation will occur due to the coalescence of a black hole binary,

Gravitoastronomy with neutron stars [PDF]

open access: yes, 2004
Recent advances in gravitational wave detectors mean that we can start to make astrophysically important statements about the physics of neutron stars based on observed upper limits to their gravitational luminosity.

Search for gravitational-wave bursts in LIGO data from the fourth science run [PDF]

open access: yes, 2007
The fourth science run of the LIGO and GEO 600 gravitational-wave detectors, carried out in early 2005, collected data with significantly lower noise than previous science runs.
