Hopefully someone with more astromomy knowledge can help me here: Is this just material from the accretion disk that is being ejected somehow? It's not material that has past the event horizon? (As far as we know material that has crossed that threshold cannot come back, right?)

> Cendes and the team don't know what's causing black holes to "switch on" after many years, but whatever it is definitely does not come from inside the black holes.
