Toolscosmo

A Python package for cosmological calculations required to study large-scale structures. Full documentation (with examples, installation instructions and complete module description) can be found at readthedocs.

Note: Some modules in the package are still under active development. Please contact the authors if you encounter any issues.

Package details

The package provides tools to model standard cosmology and its extensions. Currently, Toolscosmo supports the following calculations:

• Cosmological calculators: Various functions for cosmological calculations and conversions.

• Matter power spectrum:

  • Interface with Boltzmann solvers (e.g., CLASS and CAMB) to simulate the linear power spectrum.
  • Model the non-linear power spectrum using the halo model.

• Emulators: Machine learning-based models for:

  • Fast simulation of the linear power spectrum.

• Halo mass function: Probability distribution function of dark matter halo masses.

For detailed documentation and usage instructions, see the contents page.

Under Development

• Dark matter merger trees: Analytical merger trees using the extended Press-Schechter formalism.

• Initial Condition Generator: Lagrangian Perturbation Theory (LPT) based initial condition generator for cosmological numerical simulation frameworks.

INSTALLATION

To install the package from source, one should clone this package running the following::

git clone https://github.com/sambit-giri/toolscosmo.git

To install the package in the standard location, run the following in the root directory::

python setup.py install

In order to install it in a separate directory::

python setup.py install --home=directory

One can also install the latest version using pip by running the following command::

pip install git+https://github.com/sambit-giri/toolscosmo.git

The dependencies should be installed automatically during the installation process. The list of required packages can be found in the requirements.txt file present in the root directory.

Tests

For testing, one can use pytest. To run all the test script, run the following::

python -m pytest tests
