Observed 2D (top) and 1D (bottom) NIRSpec PRISM spectra of the five interlopers observed by the CAPERS survey. Bottom panels: Noise RMS shown as the gray dashed line, while the red dashed lines highlight the wavelength of the detected features. The best-fit template obtained by fitting the CEERS_15937 spectrum with BAGPIPES is shown in yellow in the relevant panel. The inset in the UDS_56824 panel shows the 3 × 3 arcsec ALMA Band 7 map centred at the position of the object (black square), with the relevant beam size shown on the lower-left corner.
