Caption: Figure 3.

346.5 GHz continuum emission; moments 0, 1, and 2 for 12CO J = 3 → 2; and moment 0 of Si0 J = 8 → 7. Moment 0 contours of 8 and 45 Jy/beam km s−1 of 12CO J = 3 → 2 are shown in black for all images to highlight the nuclei and extended emission. A systemic velocity of 5338 km s−1 is assumed for moment 1.
