FTFA: "The cloud might be evidence that AGNs convert and transfer their enormous gravitational prowess, by a yet-unknown process, into magnetic fields and cosmic rays that spread across the universe."
That's how :-) but clearly Hawking radiation is not a relevant process as it is far too weak from supermassive black holes.
Black holes that are accumulating mass from accretion disks are the source of huge amounts of radiation as the matter spirals around and into the hole and heats up enormously in the process. I believe the process is one of the most efficient ways of converting matter into energy that the Universe comes up with.
