glworia

A python package for gravitational-wave lensing computations including wave-optics effects.

Key Features

• Compute the frequency-dependent lensing amplification factor
• Use your custom lens model, any spherically symmetry lens is supported
• The only function you need to provide is the Fermat potential - jax will take care of the rest with auto differentiation!
• Build interpolation tables for your lens model
• Perform Bayesian parameter estimation with bilby
• Runs on GPUs

Installation

pip install glworia

Usage

Basic usage examples can be found under the Examples tab on the left.

Parameter estimation results

The full corner plots for the parameter estimation runs shown in the companion paper can be found in the plots/ directory. The setting files for these runs are in the PE_submission_settings/ directory.
