COSMOlogical Parmeterization And Scalar fields Solver - COSMOPASS

COSMOPASS can be used to calculate the different Cosmological models, which includes different Dark Energy Parameterisation , scalar fields such as minimally coupled quintessence, tachyon and galileon fields. It can be easily integrated with emcee and pymultinest.

Installing

pip install cosmopass

Getting Started

The package cosmopass has organised as the tree shown below. Here the submodule equations is the mirror of publicaly available package ScalPy.
