Synthesizer is an open-source python package for generating synthetic astrophysical observables. It is modular, flexible and fast.

This documentation provides a broad overview of the various components in synthesizer and how they interact. To get started please take a look at the getting started guide, which contains download and installation instructions, as well as an overview of the code.

For detailed examples of what synthesizer can do, take a look at the examples page. Check out the API for exhaustive details on all synthesizer functionality.
