Gravitons detected around black holes?

Could Gravitons be causing this Black Hole turbulence?

In the article above they talk about how the Gravity around Black holes is bumpy or has Gravity turbulence. Does this discovery give any evidence to the undiscovered Graviton? Because Black Holes have so much mass and warp space to such a degree, if the particles exist then around a black hole they should be more concentrated then anywhere else in the Universe. This high concentration would lead to Gravity turbulence when particles collide right?

The word graviton doesn't appear in this article. Why would you think that's what it was talking about?

I'm sorry if my title mislead you. I'm just trying to get the opinion of others about the possibility that gravitons are causing the turbulence.
