Runaway Black Holes from the Big Bang or Super Nova Runaway BHs (Tadpoles) seem the origin of Dual Herbig Haro Spiral Galaxy Systems and all other Galaxy Shapes after multiple Galaxy merging like Globular-, Ellipticals-, Irregular Galaxies and Starclusters around larger Galaxies.

Below: The Main Cosmic Filaments seem to be formed by the splitting Runaway Black Holes from the Big Bang, leaving trails of star formation behind.
Casiopeia A: Two kinds of Super Nova Runaway Black Holes searching for an equal sized Partner to Form a Herbig Haro system And the Secondary Starspot Black Holes forming the globular Plasma Ring (Q-FFF Theory)
Below: A Second example of massless Runaway Starspot Black Holes "The Hand of God" However with a Neutron star, NOT a central Super Nova BH.
Below: Proplyds or Tadpole Micro Black Holes propelled by self produced plasma tails, shooting through the old Super Nova nebula searching for an equal partner to form a dual black hole Herbig Haro starforming system. This seems the only starforming principle in the universe.
Below; Is there a left-handed magnetic field in the solar neighborhood as a sign (need) for our Material Universe ? Just like the negative electric Birkeland charge of all Black Holes.
