Zoom on the central 500 pc of the PAWS CO(1−0) intensity map (moment-0) at 1′′ resolution, with VLA 20 cm contours (Dumas et al. 2011), as well as [OIII] and [NII] + Hα from HST, indicating the ionisation region (Bradley et al. 2004); the panel on the right highlights how the ionisation region is associated with under-luminous CO emission (blue shaded area), while CO seems to accumulate towards the edge of the jet (red shaded area), supporting and expanding recent findings by Morganti et al. (2015).
