H₂ 0–0 S(3) emission-line morphology (top), velocities (centre), and FWHM line widths (bottom) with the JVLA 8.4 GHz radio continuum shown as thick contours near the centre. Thin contours show the emission-line morphology in the top left panel to ease orientation. Left to right: single-component fit, systemic line component, and blue-shifted line component. The emission-line morphology and single-component and systemic velocity maps show an hour-glass gas morphology with a strongly blue and red-shifted bipolar velocity field, consistent with a pair of bubbles that are being inflated by the radio source at the centre.
