According to the Quantum FFF Model, black holes do not eat stars, plasma or other Fermionic matter.
Even neutron stars should not be able to merge with black holes, because fermionic matter is based on Fermion propeller particles always keeping the propeller nose into the incoming Axion/Higgs ether wind.
Only black hole nuclei are able to transfer the Central Galaxy Black hole horizon.
Conclusion: Neutron stars first have to merge into small (electric dark matter) black holes before entering the central BH.

In the Big Bang process we observe the opposite process:
It is called young "oddly pickle-shaped," in the young universe.
Quantum FFF Theory has the answer.
Those pickles are big bang splitting splinters or: electric dark matter black holes.
Each newly born galaxy need to start with a central star in between two or multiple new physics
Electric Dark matter Black Holes (EDMBHs) also observed as Herbig Haro hotspots.
For multiple EDMBH galaxy see below for "oddly pickle-shaped," early galaxies.
