To All.
In my essay, Pg. 3 and under Halton Arp, I present the argument that mass, falling into the Seyfert galaxies, is "transformed" into new galaxies, but don't dig more deeply into this transformation phase. Observe that the Seyfert galaxies all have Active Galactic Nuclei. Observe, also, that the Seyferts at the center of a Galaxy Cluster is many times more massive than the average Seyfert, and so it should not be unexpected that it would behave differently.
As the Galaxy Cluster adds more mass it is the very center of the nucleus of the Seyfert that reaches a critical mass first and that nuclear ignition is initiated. The added pressure of the fireball causes it to expand (within the nucleus) until its surface pressure no longer reaches the needed critical mass and no more ignition occurs.
Observe that this entire explosion occurs within the nucleus itself and, so, causes the internal pressures to grow far beyond the critical mass. It is within this super-dense fireball that the various elements and other masses are transformation into the simple elements found in the new galaxies that are formed from the Quasars.
How these Quasars, with the mass of entire galaxies, are ejected from the Seyfert is thought to be electro-magnetic, with the Quasars traveling out through the magnetic poles of the Seyfert.
