VLA high-resolution 1.4 and 8.4 GHz mapping of the barred galaxy NGC 3367

We report new radio continuum observations with an angular resolution of 2″.1 at 1.4 GHz (20 cm) and 0″.28 at 8.4 GHz (3.6 cm) of the barred galaxy NGC 3367. In the map at 1.4 GHz, the central nuclear region connects to the southwest lobe, with a projected structure at a position angle (P.A.) of ∼230°, forming a jet-like structure. The map at 8.4 GHz shows a compact unresolved source (smaller than 65 pc in diameter) associated with emission from the nucleus and several compact sources located within a radius of about 300 pc, forming a circumnuclear structure. The compact core, jet, and lobes form a small, low-power counterpart to radio galaxies, with a flow axis that is out of the plane of the galaxy. The flow axis (P.A. ∼ 230°) coincides with the P.A. of the major axis of the galaxy and is thus inclined to the rotation axis of the disk. In addition, the flow axis differs by about 20° from the major axis of the stellar bar. Assuming that the stellar bar rotates counterclockwise (i.e., assuming trailing spiral arms), this difference in angle is taken as an argument in favor of having the jetlike structure out of the plane of the disk and not associated with the stellar bar.
