Model exploration in gravitational-wave astronomy with the maximum population likelihood [PDF]
Physical Review Research, 2022 Hierarchical Bayesian inference is an essential tool for studying the population properties of compact binaries with gravitational waves. The basic premise is to infer the unknown prior distribution of binary black hole and/or neutron star parameters ...

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

Bilby: A User-friendly Bayesian Inference Library for Gravitational-wave Astronomy [PDF]
Astrophysical Journal Supplement Series, 2018 Bayesian parameter estimation is fast becoming the language of gravitational-wave astronomy. It is the method by which gravitational-wave data is used to infer the sources’ astrophysical properties. We introduce a user-friendly Bayesian inference library

Massively parallel Bayesian inference for transient gravitational-wave astronomy
Monthly notices of the Royal Astronomical Society, 2020 Understanding the properties of transient gravitational waves (GWs) and their sources is of broad interest in physics and astronomy. Bayesian inference is the standard framework for astrophysical measurement in transient GW astronomy.
