Synthesizer

Synthesizer is a python package for generating synthetic astrophysical spectra. It is intended to be modular, flexible and fast.

Here are just some examples of what synthesizer can do:

• generate spectra for parametric star formation and metal enrichment

• generate spectra for galaxies from particle-based cosmological hydrodynamic simulations

• measure spectral diagnostics for given spectra

• easily compare stellar population synthesis models

• apply screen dust models to intrinsic spectra
