Reply to comment by smurficus103 in For the first time, astronomers have observed how certain supermassive black holes launch jets (outflows of ionised matter) of high-energy particles into space by The_R3venant

The paper states the following "particles become energized over a limited volume, for example at a shock front, and then advect or diffuse away from that region" which indicates these particles are energised before entering the event horizon so it doesn't appear to be a process that occurs within the EV. Nothing is being "ejected", it's being forced away.

IANAP but sounds like what they're saying is if anything manages to get knocked out of a black hole's orbit while traveling at relativistic speeds then that means it has to have an enormous amount of energy to fight out of that gravitational well.
