Cartoon of nuclear system of Zw49.057. The collimated dense outflow that is traced by the high-velocity HCN emission is indicated with dashed red and blue arrows. Rotating wide-angle wind as traced by the lower velocity HCN emission is indicated by the hollow bi-spheres. Dotted lines are added to the ends of the hollow bi-cones to indicate their extension further out. The outflowing OH megamaser emission is excited toward the regions indicated by dotted orange ellipses. H₂CO megamaser emission (FMM) is excited in the inner regions of the nuclear disk, indicated by dotted magenta. We have furthermore drawn the extended nuclear disk in semitransparent gray-scale, as well as the large-scale radio jet, that is differently inclined from the outflow system traced by HCN and OH.
