According to Justin Read. (Surrey):

1; Dwarf Galazies with MORE star formation have LOWER central matter densities.
2; This is reason to suggest, that the local dark matter is heated up ( cusps) by baryonic processes.
3: If so, this solves the Cusp/Core problem for dwarf galaxies in the LCDM ( Lambda Cold Dark Matter model)
Quantum FFF Theory says however:
1: Dark Matter is the same as ( non singularty) Black Holes with different "masses" or better Axion/ Higgs particle nuclear seizes. (being the Cusp origin in some Dwarfs.)
2 Star formation stops around central black holes growing by eating smaller black holes.
3 Star formation can only start between two equal sized black holes often recognized as Herbig Haro systems. which represent the center of the cusps.
