CLASS-PT: nonlinear perturbation theory extension of the Boltzmann code CLASS

Authors: Mikhail (Misha) Ivanov and Anton Chudaykin

with major inputs from other people, especially Marko Simonovic and Oliver Philcox

This is a modification of the CLASS code that computes the non-linear power spectra of dark matter and biased tracers in one-loop cosmological perurbation theory.

Getting started

Read these instructions for the installation details.

The installation instuctions for CLASS can be found on the official code webpage https://github.com/lesgourg/class_public

Once you are all set, check out this jupyter notebook for the examples of working sessions.

You can also use the Mathematica notebook 'read_tables.nb' to read the code output.

Using the code

You can use CLASS-PT freely, provided that in your publications you cite at least the code paper arXiv:2004.10607. Feel free to cite the other companion papers devoted to new large-scale structure analysis methodologies!
