General purpose and references

GLAM is a Python software that will allow you to derive the gas density, metallicity, and deviations from the Kennicutt-Schmidt relation of a galaxy with known star formation rate surface density (Sigma_SFR), known [CII] surface brightness, and known surface brightness of an ionized gas tracer (e.g. Halpha, [OIII]5007, [OIII]88um, ...). Details on the rationale, the model implementation, and on the equations are discussed in the following papers:

Requirements

The code is tested for Python >3.9. It requires Pyneb, emcee, corner.
