FlamingoBaryonResponseEmulator

A Gaussian process emulator predicting the baryonic response for a range of wavelengths, redshifts, and galaxy formation model trained on the FLAMINGO suite of simulations.

Installation

The package can be installed easily from PyPI under the name FlamingoBaryonResponseEmulator, so:

pip3 install FlamingoBaryonResponseEmulator

This will install all necessary dependencies.

The package can be installed from source, by cloning the repository and then using pip install -e . for development purposes.

Requirements

The package requires a number of numerical and experimental design packages. These have been tested (and are continuously tested) using GitHub actions CI to use the latest versions available on PyPI. See requirements.txt for details for the packages required to develop the emulator. The packages will be installed automatically by pip when installing from PyPI.
