Synthesizer

Synthesizer is a Python package for generating synthetic astrophysical observables. It is modular, flexible, extensible and fast.

Read the documentation here.

Getting Started

The latest stable release of Synthesizer can be installed directly using pip,

pip install cosmos-synthesizer

Please refer to the installation documentation for further information.

Various configuration options can also be set at installation (see here).

Getting Grids

In most use cases you will need a grid of theoretical spectra. Premade grids can be downloaded from the grids data server.

Note that you can also create your own grids using (or adapting) the grid-generation repo.

Contributing

Citation & Acknowledgement

A code paper is currently in preparation. For now please cite Vijayan et al. 2021 if you use the functionality for producing photometry, and Wilkins et al. 2020 if you use the line emission functionality.
