Top left: H₂ 1-0 S(1) emission integrated within v ∈ [200, 500] km/s. Overlaid contours show the CO(1-0) outflow emission integrated within the same velocity range, corresponding to [60σ, 100σ, 140σ, 180σ] with 1σ = 0.05 Jy km s⁻¹ beam⁻¹. Top right: H₂ 1-0 S(1) emission integrated within v ∈ [500, 800] km/s. Overlaid contours show the CO(1-0) outflow emission within the same velocity range, corresponding to [6σ, 12σ, 18σ, 24σ] with 1 σ = 0.07 Jy km s⁻¹ beam⁻¹. Bottom left: Total H₂ 1-0 S(1) velocity map (i.e. same as shown in Fig. 5), with overlaid contours corresponding to the [CI](1-0) red- and blue-wing outflow emission. The crosses mark the AGN positions. Bottom right: Peak-normalised [CI](1-0), CO(1-0), and H₂ 1-0 S(1) spectra extracted from an aperture width diameter ∼0.2″ centred on the peak of highly redshifted molecular gas emission (‘red blob’) seen in the two maps in the top panels, at coordinates RA = 16:52:58.9219, Dec = 02:24:04.00355.
