摘要

Narrowband emission-line and continuum images obtained in subarcsecond seeing conditions are presented for the Seyfert 2 galaxy, Markarian 573. Images in the emission lines of [O Ⅰ], [O Ⅱ], [O Ⅲ], [S Ⅱ], and Hα + [N Ⅱ] are used to measure the structure and excitation in the extended emission regions surrounding the active nucleus. The biconical region contains a variety of complex features, including two arclike structures within ～ 2″ of the active nucleus that appear to be associated with the extended radio continuum emission in the sense that the radio lobes lie just inside the centroids of the emission-line arcs. These arcs probably arise from an interaction between the ISM and the radio plasma from the active nucleus. Two other emission-line features lie ～3″-4″ on either side of the nucleus, and appear to be elongated nearly perpendicular to the symmetry axis of the inner radio and optical structures. The existence of multiple emission-line components could be evidence for episodic ejection of radio plasma from the active nucleus.
