Weren’t these all sparse elliptic galaxies? Didn't they all lack a SMB core? Is it possible they are whisps of parts of galaxies thrown off in a galactic collision? Like two spiral arms synchronizing and flying off, then coalescing far from the dark matter, which consolidates in the merged galaxy. These degenerate galaxies might then understandably have little/no dark matter of their own.

That's called a "just so" story. Scientists are not gentle about those. It's all, "show me the math or GTFO!". Understandable, really.

    It was a valid question. But the details matter too much for it to have an answer.
