VLT/SINFONI observations. From top to bottom, integrated flux (in arbitrary units), velocity (in km s⁻¹), and velocity dispersion (in km s⁻¹) maps of the H₂ line at 2.12 μm (left panels) and [Si VI]λ1.96 μm line (right panels). In the top-right panel, the thick orange dashed lines indicate the approximate opening angle of the [O III]λ5007 ionization cone (Thomas et al. 2017). We note that in these SINFONI maps, the fitted emission does not fully cover the 3.9″ × 4.2″ FoV. The colors and the contours are on a linear scale. The (0, 0) point in all the panels corresponds to the peak of the SINFONI line maps. The hatched circle in the bottom-right panel shows the angular resolution (FWHM) of the observations.
