Left panel: we overlay the CO(2–1) contour map (levels as in Fig. 3) on the image of linear polarization of dust emission obtained in the H band by Gratadour et al. (2015) (color logarithmic scale from 1.5% to 13%). Right panel: same as left panel but showing the comparison between the CO(3–2) map and the polarization degree. The magenta lines identify the region occupied by the AGN wind bicone modeled by Das et al. (2006): PA_outflow = 30°, FWHM_outer = 80° (see also Barbosa et al. 2014).
