(Left) [CII] 158 μm spectrum of each galaxy, extracted inside a circular aperture of 1″ radius. (Center) Integrated intensity map of each galaxy. The contours show a 2σ detection (dotted line), then increase up to 9σ (solid lines) in 1σ steps. The color scale indicates the [C II]-integrated line flux in units of jansky-kilometre per second per beam. (Right) Dust continuum emission. The contours start at 2σ (dotted line), then increase up to 5σ (solid lines), also in 1σ steps. The color scale indicates the dust continuum flux in units of millijansky per beam. The beam size is shown in the bottom-left corner of both the integrated intensity and continuum maps. J152555+4304 was not detected in the continuum.
