The most remarkable finding is that of an intriguing two-sided, filamentary structure emanating from A-nucleus, which we interpret as an outflow that extends up to at least 14 arcseconds from the A-nucleus in the N-S direction ($\\approx$ 5 kpc deprojected size) and accounts for almost 40% of the extended emission of the entire galaxy system.
