COLIBRI: cosmological libraries in Python

Presentation

COLIBRÌ (which roughly stands for “Cosmological Libraries”) is a set of Python files containing useful routines to compute cosmological quantities such as ages, distances, power spectra, correlation functions. It supports Lambda-CDM cosmologies plus extensions including massive neutrinos, non-flat geometries, evolving dark energy (w0-wa) models and numerical recipes for f(R) gravity. These files are built especially for large-scale structure purposes.

It is compatible with Python 3. Furthermore, it can interact with the Boltzmann solvers CAMB (by Antony Lewis and Anthony Challinor) and Class (by Julien Lesgourgues).

Please, cite the GitHub repository ( https://github.com/GabrieleParimbelli/COLIBRI ) if you use this library.

FYI, “colibrì” is the Italian for “hummingbird”.
