Search for Lensing Signatures in the Gravitational-Wave Observations from the First Half of LIGO–Virgo’s Third Observing Run [PDF]

open access: yes, 2021
We search for signatures of gravitational lensing in the gravitational-wave signals from compact binary coalescences detected by Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) and Advanced Virgo during O3a, the first half of their ...

Gravitational Lensing of Continuous Gravitational Waves [PDF]

open access: yesUniverse, 2021
Continuous gravitational waves are analogous to monochromatic light and could therefore be used to detect wave effects such as interference or diffraction. This would be possible with strongly lensed gravitational waves. This article reviews and summarises the theory of gravitational lensing in the context of gravitational waves in two different ...

A Spaceborne Mounting Method for Fixing a Cubic Fabry–Pérot Cavity in Ultra-Stable Lasers

open access: yesApplied Sciences, 2022
A spaceborne mounting method for fixing a 100 × 100 × 100 mm cubic Fabry–Pérot (FP) cavity is presented. The method constrains the FP cavity in eight directions with a titanium bracket, PEEK gaskets, and vacuum glue.

Gravitational-wave physics and astronomy in the 2020s and 2030s

open access: yesNature Reviews Physics, 2021
The 100 years since the publication of Albert Einstein’s theory of general relativity saw significant development of the understanding of the theory, the identification of potential astrophysical sources of sufficiently strong gravitational waves and ...

Squeezing for cosmic symphony

open access: yesAAPPS Bulletin, 2023
We briefly review the status of applying quantum squeezing to aid the search for gravitational waves with km-scale laser interferometers operating in the audio frequency band.

Stochastic gravitational-wave background as a tool for investigating multi-channel astrophysical and primordial black-hole mergers [PDF]

open access: yesAstronomy & Astrophysics, 2021
The formation of merging binary black holes can occur through multiple astrophysical channels such as, e.g., isolated binary evolution and dynamical formation or, alternatively, have a primordial origin.

Advanced Virgo: a second-generation interferometric gravitational wave detector [PDF]

open access: yes, 2014
Advanced Virgo is the project to upgrade the Virgo interferometric detector of gravitational waves, with the aim of increasing the number of observable galaxies (and thus the detection rate) by three orders of magnitude. The project is now in an advanced

Using DWS Optical Readout to Improve the Sensitivity of Torsion Pendulum

open access: yesSensors, 2023
In space gravitational wave detection missions, a drag-free system is used to keep the test mass (TM) free-falling in an ultralow-noise environment.
