The missing link in gravitational-wave astronomy: A summary of discoveries waiting in the decihertz range. [PDF]

Exp Astron (Dordr), 2021
Since 2015 the gravitational-wave observations of LIGO and Virgo have transformed our understanding of compact-object binaries. In the years to come, ground-based gravitational-wave observatories such as LIGO, Virgo, and their successors will increase in

Waveform uncertainty quantification and interpretation for gravitational-wave astronomy [PDF]

Classical and quantum gravity, 2023
We demonstrate how to quantify the frequency-domain amplitude and phase accuracy of waveform models, δA and δφ, in a form that could be marginalized over in gravitational-wave inference using techniques currently applied for quantifying calibration ...

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

Scientific 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.

Parallelized inference for gravitational-wave astronomy [PDF]

Physical Review D, 2019
Bayesian inference is the workhorse of gravitational-wave astronomy, for example, determining the mass and spins of merging black holes, revealing the neutron star equation of state, and unveiling the population properties of compact binaries.

Primordial black holes—perspectives in gravitational wave astronomy [PDF]

, 2018
This article reviews current understanding of primordial black holes (PBHs), with particular focus on those massive examples (≳1015 g) which remain at the present epoch, not having evaporated through Hawking radiation. With the detection of gravitational

A High-Finesse Suspended Interferometric Sensor for Macroscopic Quantum Mechanics with Femtometre Sensitivity [PDF]

Sensors
We present an interferometric sensor for investigating macroscopic quantum mechanics on a table-top scale. The sensor consists of a pair of suspended optical cavities with finesse over 350,000 comprising 10 g fused silica mirrors.

On-Ground Testing of Dual-Sided Release Mechanism of TianQin Test Mass Using a Pendulum [PDF]

Sensors
The high-precision gravitational reference sensor, which hosts a heavy test mass (TM) surrounded by electrodes with a relatively large gap, is crucial in all high-sensitivity drag-free sensors.
