8c. Galaxies with Apparent Companions which are Double

A related class to the one just discussed contains galaxies which have an apparent companion which is double. Again most of the double companions are interacting doubles. This kind of apparent companion is of interest because of the report by Sulentic, Arp and di Tullio (1978) that non-equilibrium companions are more frequent near large galaxies than they are in the general field. The sub-category of double companion is introduced here by page 8.16 where companions are shown which are just detectable as doubles. Succeeding pages show double apparent companions which are less close together. On page 8.18 the galaxy AM 0055-491 has two double companions and both pairs are almost on a line across the galaxy. On page 8.20 an interacting triple is shown near the large galaxy AM 2341-321. This object was shown also in Category 3: Interacting Triples. The final member of this sub-category is shown on page 8.21; the picture is a 4m CTIO plate (1397A) of AM 043-472; the companion is a very disturbed interacting double, possibly triple, and the main galaxy as well may be interacting with some small nearby galaxies.
