We investigate whether strong molecular and atomic emission lines at far-infrared wavelengths can influence the identification and derived properties of galaxies selected from broad-band, far-infrared or submillimetre observations. Several of these lines, for example, [C ii] 158 μm, have been found to be very bright in some galaxies, with fluxes of ≳0.1–1 per cent of the total far-infrared luminosity, and may be even brighter in certain populations at high redshifts. At redshifts where these… Expand
