Caption: Figure 5.
A 12.″0 × 12.″0 composite image (blue: F115W; green: F277W; red: F444W) centered at the position of the z = 16.7 candidate from Donnan et al. (2023; magenta square). The deep SCUBA-2 850 μm map from Zavala et al. (2017) shows a ∼2.6σ positive emission at this position (white contours indicate 1σ and 2σ levels). We also plot signal-to-noise contours at 1σ, 2σ, 2.5σ, 3σ, and 4σ from Spitzer 8 μm and 24 μm as cyan and red lines, respectively, and from VLA 3 GHz as yellow dashed lines. From the lack of clear detections, we can rule out an obvious alternate radio or 24 μm counterpart for the 850 μm emission at z ≲ 3, while we cannot rule out galaxies at z ≳ 3 since they are usually undetected at these wavelengths. The marginal 8 μm emitter on the top right (west) of CEERS-93316 is a potential counterpart, but the current data are unconstraining.
