Pylians stands for Python libraries for the analysis of numerical simulations. They are 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). Pylians3 evolved from Pylians to support python3. 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

Pylians were the native or inhabitant of the Homeric town of Pylos.
