Radiative transfer models for galaxies and active galactic nuclei (AGN) are now routinely used for interpreting multi-wavelength observations of galaxies and are increasingly being incorporated in simulations of galaxy formation and evolution.
CYGNUS (CYprus models for Galaxies and their NUclear Spectra) is a collection of radiative transfer models for AGN tori (Efstathiou & Rowan-Robinson 1995, Efstathiou et al. 2013), starburst galaxies (Efstathiou, Rowan-Robinson & Siebenmorgen 2000, Efstathiou & Siebenmorgen 2009) and host galaxies (Efstathiou & Rowan-Robinson 2003, Efstathiou et al. 2021).
The models are currently available as grids of models stored in Python structures and a README file is provided for each set of models as indicated in the table below.
