I’m not sure if this is a collisional ring or the remnants of a dwarf galaxy which collided with the bigger galaxy:
188.5510, 11.8108
356.0738, -0.0576 Overlap?
219.3946, 18.6869
153.3263, 1.4271 Multiple galaxies merging and sharing their mass. (This is not a typical multi-galaxy mergers I see)
136.4647, 1.1303 amazing overlap
this one is also peculiar and I think it needs more research:
2.5036, 3.8622
Possible Jellyfish Galaxies
197.2124, 0.7943
197.5259, 0.5865
225.1932, 7.6333 tidal tail and a ring
