| Description | This is a puzzling galaxy with what looks like at least 2, and possibly 3, elliptical galactic centers at slightly different orientations. The result is a galaxy with a much larger and more elongated, irregular center than normal. Arp categorizes this as having "the appearance of fission", and I suppose that's possible if you thought that there exists a mechanism for fission. Arp was not a fan of galactic merging... but I certainly think that incomplete fusion is the more likely explanation of the appearance here, given that gravity is a simple mechanism, and that mergers are now a broadly accepted mechanism for galactic evolution. |
