Welcome to gwcosmo

Gwcosmo: a package to estimate cosmological parameters using gravitational-wave observations.

Installation

The recommended method for installing gwcosmo is using pip. We recommend setting up a virtual environment first. Once you have done this and activated your virtual environment, simply run

pip install gwcosmo

Note that gwcosmo requires Python version 3.8 or higher.
