The [NII] 205 integrated line maps and the corresponding continuum maps of the submillimeter galaxies (upper panel) and the quasar hosts (lower panel) from our sample. The [NII] 205 maps were integrated over the width of their respective [NII] 205 μm FWHM (and over the [CII] 158 μm FWHM for sources undetected in the [NII] 205 μm emission). The full (dashed) contours represent the +(-) 2σ, 4σ, 6σ, 8σ, 16σ regions, where σ is the rms noise of the integrated maps. The respective synthesized beam sizes (if present) are shown in the lower left corner of each panel. To guide the eye, a green dotted circle is placed centering the measured continuum coordinates of the source. The respective continuum maps are shown below the [NII] 205 μm integrated maps.
