I'm not quite sure what you are referring to here, but I will take a guess...
Black holes do eject
gravitons (if they exist; we are waiting on the LHC for that
one), but gravitons must be massless to fit in to our theories so far.
Perhaps I am off track there and thee is another ejection, although I don't see how
anything of mass can escape the >0 mass event horizon.
But that is not what is happening in the formation mentioned in the article.
In the article there is a black hole surrounded by a dense cloud of gas. As the
hole sucks in the gas it excites pockets of particles like bubbles of steam in a
boiling kettle. Because the excited pockets are less dense than the surrounding
gas cloud they move away from the black hole. They can move away from the
hole because they are no where near their event horizon(s).
As they rush away from the hole they leave a trail of gas in their wake. These
thin trails would normally diffuse into the surrounding gas and space as they
moved back towards the hole, however they are held in place by a weak
magnetic field as it takes more energy for the charged particles in the gas
strands to move through changes in a magnetic field than it does for them to
move through space with out a magnetic field.
*edit* Err....I'm just repeating the article in the way I find easiest to understand here.
