FOLPSν is a code for efficiently evaluating the redshift space power spectrum in the presence of massive neutrinos

FOLPSν

FOLPSν is a Python code that computes the galaxy redshift space power spectrum for cosmologies containing massive neutrinos. The code combines analytical modeling and numerical methods based on the FFTLog formalism.

Run

Dependences

The code employs the standard libraries:

• NumPy
• SciPy

We recommend to use NumPy versions ≥ 1.20.0. For older versions, one needs to rescale by a factor 1/N the FFT computation.

To run the code, first use git clone:

git clone https://github.com/henoriega/FOLPS-nu.git

or download it from https://github.com/henoriega/FOLPS-nu.

Once everything is ready, please check the Jupyter Notebook which contains some helpful examples.
