The SNova Black Hole production seems to have an own propulsion system by plasma tails pushing them away from the strongest gravity center, spreading around the galaxy bulge.
The more spreaded dark matter black holes , the flatter the rotation curve seems to be.
see below.Polar dwarf galaxy structure of the milky way is breaking up.
New Black Holes produce plasma, they accelerate by that plasma away (pushed away) from other gravity centers. they eat smaller (dual Herbig Haro) black holes and act as Dark Matter.
Equal sized black holes form Herbig Haro systems forming stars and later Galaxies in between. (According to Q-FFF Theory)
Dark Matte Black Hole distribution in the Galaxy. The galaxy always starts as a large star, with two large Herbig Haro Dark Matter Black Holes. first called Stellar Anchor Black Holes (SABHs) and after explosion of the Starspot black holes and merging of other Star systems: called Galaxy Anchor Black Holes (GABHs)
Each older galaxy has Multiple GABHs (by merger dual galaxy BHs) and multiple Supernova BHs after S-Nova black hole production.
S-Nova black holes tend to migrate away from the mass center to find an other equal sized BH to form a Herbig Haro System and form new stars.
