Fig. 7


Left: Contours of the Subaru/IRCS H-band (blue) and K-band (magenta) emission taken from Fig. 5 overlaid on the [O III]5007 channel map obtained integrating the SINFONI datacube on the line core (λ = 1236.1−1238.9 nm; corresponding to the rest-frame range 5001−5012 Å). All contours and colour level starts from 3σ with steps of +2, as labelled. Spatial scale is given in arcsec. The [O III] systemic emission is overall symmetric, except for a plume extending beyond 0.5′′ (~ 4.5 kpc) in the north-west direction. Right: same, but for the Hα line, collapsing the channels in the wavelength range λ = 1620.6−1624.0 nm (corresponding to the rest-frame range 6556−6570 Å). The same plume is also seen in the IRCS H-band data (sampling the Hα region), but it is not seen in the IRCS K-band data.
