Prospects for observing and localizing gravitational-wave transients with Advanced LIGO, Advanced Virgo and KAGRA [PDF]

open access: yesLiving Reviews in Relativity, 2018
We present possible observing scenarios for the Advanced LIGO, Advanced Virgo and KAGRA gravitational-wave detectors over the next decade, with the intention of providing information to the astronomy community to facilitate planning for multi-messenger ...

A high load torsion pendulum of trifilar suspension magnetic damper for inertial sensor test [PDF]

open access: yesScientific Reports
Space-based gravitational waves (GW) detection requires the residual noise spectral density of the inertial sensors to reach $$10^{-15}\textrm{m}\cdot \textrm{s}^{-2}\cdot \textrm{Hz}^{-1/2}$$ from 0.1 mHz to 1Hz.

Design method for the structure of a gravitational wave detection telescope with low TTL noise [PDF]

open access: yesScientific Reports
As a critical payload of the gravitational wave detection interferometry system, the tilt-to-length (TTL) noise has a significant influence on the detection accuracy of the interferometry system.

Research on Interferometric Tilt Sensor for Vibration Isolation Platform [PDF]

open access: yesSensors
Low-frequency seismic vibrations extremely limit the performance of ground simulation facilities for space-borne gravitational wave detections, which need to be substantially suppressed. Active vibration systems are thus required.

Modeling and Simulation of Inter-Satellite Laser Communication for Space-Based Gravitational Wave Detection [PDF]

open access: yesSensors
Space-based gravitational wave detection uses an equilateral triangular satellite constellation with inter-satellite laser heterodyne interferometry to measure displacement variations caused by gravitational waves.

A Broadband Signal Recycling Scheme for Approaching the Quantum Limit from Optical Losses

open access: yesGalaxies, 2021
Quantum noise limits the sensitivity of laser interferometric gravitational-wave detectors. Given the state-of-the-art optics, the optical losses define the lower bound of the best possible quantum-limited detector sensitivity.

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.

Gravitational-wave asteroseismology with fundamental modes from compact binary inspirals

open access: yesNature Communications, 2020
Independently measuring the tidal deformability and the fundamental oscillation mode (fmode) frequency enables tests of gravity and the nature of compact binaries.
