Description

e-MANTIS is an emulator for the study of large-scale structure formation in the context of alternative dark energy and gravity theories. It uses Gaussian Processes to perform a fast and accurate interpolation between the outputs of high resolution cosmological N-body simulations. Currently, e-MANTIS is able to give predictions for the following quantities:

• Matter power spectrum boost in \(f(R)\) gravity (described in <cite paper>).

Please cite the corresponding papers if you use e-MANTIS in your work.

More observables and cosmological models will be added in the future. Stay tuned!

Installation

You can directly clone the emulator from our public repository:

git clone https://gitlab.obspm.fr/e-mantis/e-mantis.git

The emulator needs the following python packages to be installed in order to work:

1. NumPy

2. scikit-learn

3. h5py
