Fermi Bubbles and Birkeland streams are originated by new physics dual Galaxy- and Stellar Anchor Black Holes.

Galaxy- and Stellar Anchor Black Holes are the remnants of former Dual Herbig Haro black Holes, which can be called the magic star and galaxy formation system of the universe.
All the formation systems are energized by the Penrose Trapped Black Hole Horizon effect included in the Q-FFF Theory. (see below)

The Penrose black hole Horizon effect is origin of the repulsion of dual equal sized black holes by a symmetric pushing plasma BAR or dual tail.

Even Galaxy Rotation curves are created by the different compositions of the Galaxy Anchor Black Holes. (GABHs)
