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

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.

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.

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.

No tension between assembly models of super massive black hole binaries and pulsar observations

open access: yesNature Communications, 2018
Pulsar timing arrays enable the search for the isotropic gravitational-wave (GW) background originating from super massive black hole binary populations, but impose a stringent upper limit on the GW characteristic amplitude.

Swift/UVOT: 18 Years of Long GRB Discoveries and Advances

open access: yesUniverse, 2023
The Neil Gehrels Swift Observatory (Swift) has been in operation for 18 years. The Ultra-Violet/Optical Telescope (UVOT) onboard Swift was designed to capture the earliest optical/UV emission from gamma-ray bursts (GRBs), spanning the first few minutes ...

3D characterization of low optical absorption structures in large crystalline sapphire substrates for gravitational wave detectors

open access: yesScientific Reports, 2021
Very high-quality sapphire substrates are key elements of the cryogenic Japanese gravitational interferometer KAGRA, in which they are used to build the main mirrors, working as the test masses to sense the gravitational waves.
