SWIGLAL: Python and Octave interfaces to the LALSuite gravitational-wave data analysis libraries
SoftwareX, 2020 The LALSuite data analysis libraries, written in C, implement key routines critical to the successful detection of gravitational waves, such as the template waveforms describing the merger of two black holes or two neutron stars.

The cosmological gravitational wave background from primordial density perturbations [PDF]
, 2006 We discuss the gravitational wave background generated by primordial density perturbations evolving during the radiation era. At second-order in a perturbative expansion, density fluctuations produce gravitational waves. We calculate the power spectra of

Enhancing gravitational-wave science with machine learning [PDF]
Machine Learning: Science and Technology, 2020 Machine learning has emerged as a popular and powerful approach for solving problems in astrophysics. We review applications of machine learning techniques for the analysis of ground-based gravitational-wave (GW) detector data.

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

Oscillations in the stochastic gravitational wave background from sharp features and particle production during inflation [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 We identify a characteristic pattern in the scalar-induced stochastic gravitational wave background from particle production during inflation. If particle production is sufficiently efficient, the scalar power spectrum exhibits 𝒪(1) oscillations periodic

Gravitational wave detector response in terms of spacetime Riemann curvature
, 2013 Gravitational wave detectors are typically described as responding to gravitational wave metric perturbations, which are gauge-dependent and --- correspondingly --- unphysical quantities.

GWBENCH: a novel Fisher information package for gravitational-wave benchmarking [PDF]
Classical and quantum gravity, 2020 We present a new Python package, gwbench, implementing the well-established Fisher information formalism as a fast and straightforward tool for the purpose of gravitational-wave benchmarking, i.e.
