WebNov 30, 2024 · Gravitational wave parameter estimation has rapidly evolved from point-wise parameter estimation [ 14 – 16] to the use of neural networks dropouts to provide estimation intervals [ 47 ], and to output a parametrized approximation of the corresponding posterior distribution [ 48 ]. WebIt is the method by which gravitational-wave data is used to infer the sources' astrophysical properties. We introduce a user-friendly Bayesian inference library for gravitational-wave astronomy, Bilby. This Python code provides expert-level parameter estimation infrastructure with straightforward syntax and tools that facilitate use by beginners.
