According to Quantum FFF theory, Fermions are generally pushed from the black hole horizon!!! due to the Fermion propeller shape and opposite Lorentz polarisation against the Higgs vacuum B-H inflow.
Only all radiation will be absorbed by the black hole and NOT radiated back  (thus NO Hawking radiation) which feeds the black hole and let the black hole grow from a certain nuclear size!!
I would call it the "CRITICAL Black Hole SIZE" as predicted by the Quantum FFF theory, which says:
The (multi) universe is bouncing or pulsating 
It is contracting:
1: by the absorption of the dense Higgs vacuum by all black holes,
(also the origin of the Hubble redshift)
2: by the continuous formation of Super Nova black holes.
It is expanding :
1: by the evaporation of primordial Big Bang black hole splinters into a dense higgs vacuum, only AT THE OUTSIDE OF THE RASPBERRY shaped MULTIVERSE, as long as there are splinters left over from the big bang.
2: by the evaporation of small black holes which are under the "CRITICAL B-H SIZE'"

CONCLUSION:
1: The universe seems to expand by the BH vacuum absorption based Hubble redshift.
2: I also seems to accelerate its expansion because the photons coming from far away have to pass more vacuum absorbing black holes areas.
3: The micro-B-H 's based plasma created inside the Vajra system will evaporate and as a consequence have to be continuously powered by new overunity electricity created by the system itself. 

Recently there is a discussion going on about what BH really are:

NEW paradigm DARK MATTER BLACK HOLES are not related to X-RAY HOT GAS CONCENTRATIONS

We need the new Black Hole paradigm of "Quantum FFF Theory" to explain the so called discrepancy between "the areas of strong X-ray emission and the largest concentrations of mass seen through gravitational lensing" observed inside colliding galaxies.
Q-FFF theory states that Dark Matter Black Holes tend to pair in groups and create so called white holes in between (the middle) as a concentration point for newly formed H2 gas formed around the black hole horizons and universal ionized dust to create open star clusters or radio galaxies like Cygnus A.


NEW paradigm Dark Matter Black Holes are supported by What we can learn from: "Dark Matter a Primer" by K.Garret and G.Duda.
"3.3.
Recent evidence hailed as the “smoking-gun’’ for dark matter comes from the Bullet cluster, the result of a subcluster (the “bullet’’) colliding with the larger galaxy cluster 1E 0657-56. During the collision, the galaxies within the two clusters passed by each other without interacting (a typical distance between galaxies is approximately one megaparsec, or 3.26 million lightyears). However, the majority of a cluster's baryonic mass exists in the extremely hot gas between galaxies, and the cluster collision (at roughly six million miles per hour) compressed and shock heated this gas; as a result, a huge amount of X-ray radiation was emitted which has been observed by NASA's Chandra X-ray Observatory. Comparing the location of this radiation (an indication of the location of the majority of the baryonic mass in the clusters) to a mapping of weak gravitational lensing (an indication of the location of the majority of the total mass of the clusters) shows an interesting discrepancy; the areas of strong X-ray emission and the largest concentrations of mass seen through gravitational lensing are not the same. The majority of the mass in the clusters is nonbaryonic and gravity “points’’ back to this missing mass [27]."

Conclusion:
We have to look for combined radio radiation and gravitational lensing to search for Dark matter concentrations.
Only light x-ray radiation will be found around these Black Holes, which is outshined by the radio radiation in the LOFAR image above..

Trails of "Stray stars" expelled from colliding galaxies is a supposrt for the existence and proliferation of dark matter black holes spread through Galaxies and Dwarf galaxies.
