  Modifications of jet properties resulting from the coupling of jets to the
strongly interacting matter produced in RHIC collisions are of great current
interest. In recent work, the PHENIX collaboration has applied a novel
technique to the analysis of two particle azimuthal correlations which
extinguishes the harmonic part of the underlying event revealing the true jet
shape. Recent extensions of the method to three particle correlations allow for
a more revealing study of jet topologies in Au+Au collisions at
($\sqrt{s_{_{\rm NN}}}$=200 GeV).
