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.

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

An information-theoretic approach to the gravitational-wave burst detection problem [PDF]

, 2017
The observational era of gravitational-wave astronomy began in the Fall of 2015 with the detection of GW150914. One potential type of detectable gravitational wave is short-duration gravitational-wave bursts, whose waveforms can be difficult to predict ...

Neutron Star Extreme Matter Observatory: A kilohertz-band gravitational-wave detector in the global network [PDF]

Publications Astronomical Society of Australia, 2020
Gravitational waves from coalescing neutron stars encode information about nuclear matter at extreme densities, inaccessible by laboratory experiments. The late inspiral is influenced by the presence of tides, which depend on the neutron star equation of

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

Semianalytic calculation of gravitational wave spectrum nonlinearly induced from primordial curvature perturbations [PDF]

Physical Review D, 2018
Whether or not the primordial gravitational wave (GW) produced during inflation is sufficiently strong to be observable, GWs are necessarily produced from the primordial curvature perturbations in the second order of perturbation.

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.

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

Scientific 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.

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
