Globular Clusters seem to have no Dark Matter Halos,
but central concentration of Dark Matter..
If the big bang was the splitting of a huge Axion/ Higgs particle knotty Dark Matter Black Hole (DM- BH) nucleus into smaller DM-BH nuclei, then no standard Fermion/ Baryon inflation has happened only the DM-BH based Lyman alpha forest equipped with local Herbig Haro star/galaxy creating systems.
All black holes of all sizes (down to ball lightning) seem to be equipped with a Fermion repelling- and plasma producing horizon, which has also a charge splitting effect into a negative (outside) and positive ( inside) zone ( see orientale basin of the moon) .
