According to Quantum FFF Theory, NEW Physics electric dark matter based Quasar Black Holes are assumed to be ejected as Big Bang nuclear splinters or the result of merger black holes in the center of old galaxies.
So: Quasars are not ejected by galaxies, as Halton Arp proposed, sorry for Arp, see: https://www.youtube.com/watch?v=59BXLS_hx-U
Halton Arp found multiple Quasar pairs around Seyfert galaxies, (see NGC1097 below) which I interpret as the result of the combined GABHs of merger spiral galaxies.
Quasars and Herbig Haro Systems based on Electric Dark Matter Black Holes.
Cygnus A Radio Galaxy with dual gas producing Quasars (dual
Hotspots) and growing black hole based galaxy in the center. NGC 1097 (below,
image H. Arp) as example of a merger galaxy with multiple Quasars, left over
from merger galaxy hotspots like Cygnus A.

We are not made of particles alone, but by holographic guided (Axion-Higgs) particle based fields between copy particles inside copy universes!!
