The Dragonfly Galaxy. Left: Contours of CO(6−5) emission overlaid onto the HST/NICMOS F160W image from Pentericci et al. (2001). The inset shows CO(6−5) contours of the two central components overlaid onto the HST/WFPC2 F555W image from EM15. Contour levels: 0.16 to 1.69 Jy beam^-1 × km s^-1, in steps of factor 1.4. The HST astrometry was adjusted so that the double nucleus in the HST images matches the ALMA components to within 0.2′′. The yellow diamonds represent the two components of the 8.2 GHz radio source (Pentericci et al. 2000). Right: 1.2 mm dust continuum, with the CO(6−5) contours overlaid.
