Caption: Figure 1.

A 3.″0 × 3.″0 composite image centered at the position of CEERS-DSFG-1; the JWST/NIRCam F115W observations are in blue, F277W in green, and F444W in red (the data have been smoothed to roughly match the F444W resolution for better visualization). The 1.1 mm NOEMA signal-to-noise ratio levels starting at 2.5σ to 10σ (in steps of 2.5σ) are represented by the white contours, clearly indicating that the dust thermal emission detected at submillimeter/millimeter wavelengths corresponds to the position of CEERS-DSFG-1.
