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 into models of galaxy formation and evolution.CYGNUS (CYprus models for Galaxies and their NUclear Spectra) is a collection of radiative transfer models for AGN tapered discs/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 & Siebenmorgen 2018 – in preparation). The models are currently available as grids of models stored in IDL savesets and a README file is provided for each set of models.
