Bilby: A User-friendly Bayesian Inference Library for Gravitational-wave Astronomy [PDF]

open access: yesAstrophysical 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
