There is an evidence for significant evolution in the gaseous and dust properties of galaxies since the era of cosmic noon (1 JWST high resolution near- and mid-IR imaging from the CEERS survey to disentangle the emission from the torus in unprecedented detail for 88 X-ray selected AGN at z ~ 2. Combining low-resolution multi-band photometry at UV to FIR wavelengths, from the archival CANDELS and HELP surveys, with the high-resolution JWST photometry, we employ a novel SED fitting method to constrain essential AGN and torus parameters, such as accretion disc luminosity, torus opening angle, and inclination angle. Despite the well-known evolution of the ISM and structural properties of AGN hosts to these redshifts, our population-level analysis finds no clear evidence for the evolution of the torus when compared to similar local AGN.This dataset provides the posterior distributions of 14 galaxy and AGN parameters and 1 derived AGN paramter for all 88 sources in our sample. These posterior distributions were obtained by SED fitting as described in the accompanying paper.
