> I thought that only hawking radiation could escape a black hole.

I think this is likely a misconception too. Hawking radiation does not come from inside a black hole, it comes from the event horizon. A virtual particle/anti-particle pair is created close enough to the event horizon that one of them falls in and the other escapes. This means the origin is outside the hole!

Similar story with jets. They're created by the interactions of matter as it falls towards the black hole (gaining energy), but before it actually falls inside.
