Pylians stands for Python libraries for the analysis of numerical simulations.

For the stable version do:

python -m pip install Pylians

For the development version do

git clone https://github.com/franciscovillaescusa/Pylians3.git
cd Pylians3
python -m pip install .

Pylians3 is a set of python libraries, written in python, cython and C, whose purposes is to facilitate the analysis of numerical simulations (both N-body and hydrodynamic). Among other things, they can be used to:

• Compute density fields
• Compute power spectra
• Compute bispectra
• Compute correlation functions
• Identify voids
• Populate halos with galaxies using an HOD
• Apply HI+H2 corrections to the output of hydrodynamic simulations
• Make 21cm maps
• Compute DLAs column density distribution functions
• Plot density fields and make movies
