Extended Data Fig. 4: 2D and 1D NIRSpec spectra of CEERS-93316, CEERS-DSFG-1 and two other galaxies at similar redshifts z ≈ 4.9, highlighting a potential overdensity in the field at this redshift.

The two horizontal yellow lines in the 2D spectra indicate the extraction aperture used to measure the 1D spectra. Dotted purple vertical lines indicate the ___location of several emission lines when present. The shaded grey area corresponds to 1σ uncertainties in the 1D spectra and the zero flux level is marked by a dashed black horizontal line.
