In Binary Pulse Theory: Accretion Luminosity
Same thing, new nameIn standard physics
The brilliant core of a galaxy powered by gas falling into a supermassive black hole.
In Binary Pulse Theory
A feeding Null Well near its Eddington limit; infall releases about a tenth of the rest energy, ten times fusion.
The BPT terms behind it
Accretion Luminosity is the light a feeding well gives off: about a tenth of the rest energy of what falls in, ten times more efficient than fusion, so a quasar swallowing a few Suns a year outshines a trillion stars.
The Eddington Luminosity is the most a well can shine before its light pushes back its food: near it a feeding well is a quasar, at a small part of it a Seyfert galaxy, and one whose jets reach far beyond its stars a radio galaxy.

The standard physics term is here to help you find your way in; the book itself writes in BPT's own terms. Read them in the lexicon, or start the book at Binary Pulse Theory.
