In my defense, I've read a handful of recent articles stating black holes "emit" these jets. IMO the terminology is misleading. As you clearly describe it Dan, they very well could be vortices. They sure look like it anyway. I should have read it more attentively.

These bits and pieces are what cause the particle jets. Black holes are generally very messy eaters. I recall an Asimov short story that involved a minor trapped on an asteroid who spotted a particularly small black hole passing through the Solar System. He was able to call for help by throwing stones into the black hole -- in an SOS pattern. A clever bit of a read.
