Modelling JWST mid-infrared counts II: Extension to 5.6 μm, optical, radio and X-rays
Abstract
In Paper I (Rowan-Robinson 2024), models derived in 2009 to fit mid-infrared (8-24 micron) source counts from the IRAS, ISO and Spitzer missions, were found to provide an excellent fit to deep counts at 7.7-21 mu with JWST, demonstrating that the evolution of dusty star-forming galaxies is well understood. Here the treatment of optical spectral energy distributions (SEDs) is improved and the counts are extended to 5.6 mu and optical wavelengths. The models proved a good fit to the latest, deeper, JWST counts. The models are also extended to radio and X-ray wavelengths. Predicted redshift distributions are given for a range of wavelengths and flux-densities.
