Abell 520, Hot Gas creation between approaching Dark Matter concentrations.

Abell 520,  Hot Gas creation between approaching Dark Matter bubbles just like Herbig Haro systems do between two bowshock black holes..
Evidence for dumbbell shaped Dark Matter concentrations ( multiple Galaxy Anchor Black Holes) lining up before merging. See also: Hot gas concentration between nearest approaching Dark Matter concentrations. (Q-FFF Theory) see: See: Sparse reconstruction etc. Austin Peel et al. (Uni. Paris Saclay)

Supernova Black hole creation with small Herbig Haro systems inside a nebula

The NEW black hole according to the Quantum FFF Model.

Free energy and free plasma production out of the Axion-Higgs field vacuum

Free energy and free plasma production out of the Axion-Higgs field vacuum between Two Herbig Haro Black holes (bowshocks)
Axion-Higgs vacuum pressure profiles (Butterflies) around black holes are the motors for electron and plasma compression. (Q-FFF Theory) see also: The Origin of Universal Structure: Herbig Haro Strings by Electric Dark Matter Black HoleSystems.

"Once we see an axion, we have the whole history of structure formation in our galaxy,” Rosenberg says. “So that is very exciting". However according to Q-FFF Theory, it is not the particle itself but the chirality left- or right handed of the oscillating vacuum lattice field, which I call Axion Higgs field.for dark energy and even for our material universal bubble in the multiverse. So the oscillating Axion Higgs field is NOT responsible for dark Matter.but DARK ENERGY.

Strange Objects Found at The Galactic Center

“Strange Objects Found at The Galactic Center are Like Nothing Else in The Milky Way”.(see Science alert) Or in Nature: "A population of dust-enshrouded objects orbiting the Galactic black hole"  Q-FFF Theory says:

These objects are the result of former Herbig Haro systems left by their dual bowshock black holes , (eaten by Sagr A) leaving filaments with- or wihout aplasma balls (former jets) behind.

M77 Magnetic aligned filaments between Mother Herbig Haro black holes.

Herbig Haro systems are the best free energy and free plasma creators after the big bang.
M77: Just a good example of how multiple dual Herbig Haro (HH) black holes (BHs) seem to be forced magnetically to align parallel with the original dual large Mother black holes, (A) meeting in the middle leaving a bar (B)  behind. (changing function into dual HH jet related bowshocks or: Galaxy Anchor Black Holes, perpendicular to the galaxy disc. according to Q-FFF Theory.) Each filament should represent the original dual jets between these HH BHs. (Q-FFF Theory)

The small multiple secondary HH black holes are assumed to be produced by Supernova starspot micro black holes ( see second image)

The origin of Quasars? Monster Black holes.

The origin of Quasars? Monster Black holes central in Galaxy Clusters.
According to Q-FFF Theory, normal black holes repel propeller shaped fermions ( spinning rigid strings, with a Calabi yau surface) by the large curvature angle of the horizon, 
Then Monster black holes seem to eat fermions a go go- caused by the much smaller Schwarzschild horizon curvature- angle and as a consequence become a Quasar eating all the stuff around in contrast with ejecting all femion plasma into two jets..

Question: What is the minimum black hole horizon radius to change a black hole into a Fermion eating Quasar? 
At least, less than the Abell 85 BH: 40 billion the mass of the sun, which is in line with present estimates of Quasars: Wikipedia: A Quasar is an extremely luminous active galactic nucleus (AGN), in which a supermassive black hole with mass ranging from millions to billions of times the mass of the Sun.
The smallest Quasar seems to be: PKS 0405-385. with a radiation peak variability less than an hour.
