From top to bottom pannels: Color-color diagram (using the continuum) for selecting deeply obscured nuclei using JWST/MIRI filters z = 1.5 and z = 2. Color-coded stars correspond to the host galaxy contribution of the simulated spectra shown in Fig. 1. The blue dashed lines denotes the region where sources have a contribution of the buried nuclei greater than 40%. Gray circles correspond to CEERS sources with redshift measurements. Magenta squares represent those sources at redshift ∼1.25-1.75 (top panel) and 1.75-2.25 (bottom panel).
