Dubbelosix Posted March 22, 2019 Report Share Posted March 22, 2019 More or less, yes. By the way, thinking about this some more, I should add there are other ways for gravitational potential energy to be converted into electromagnetic radiation more directly, near the edge of a black hole. There is something called "synchrotron radiation", in which charged particles drawn in by gravity encounter a magnetic field from the black hole and are thereby caused to move in a circular trajectory. This causes them to emit EM radiation. This mechanism is in fact proposed for "jets" of EM radiation seen in astronomy. More here: https://en.wikipedia.org/wiki/Synchrotron_radiation#Synchrotron_radiation_in_astronomy This radiation comes from the accelerated charges in the accretion disk and will of course supply a lot of energy coming from a black hole contributing to the luminosity of the quasar.
