    So these are uber globs, supermassive globular clusters if you will. The intermediate mass globs were assimilated and/or merged, or remain as various Omega Cens or Mayall IIs, and the "stellar" mass globs continue to merrily orbit their capturing host...

    Yeah, I'm speculating over lunch.

    And doing a mighty fine job of it too, I might say.

    I'd only add this observation. Such objects are impossible to form without dark matter. At the conditions when structures started forming in the Big Bang, without dark mater, you'd only be able to form nice globs like M13. The supermassive ones can't form without dark matter's help.
