As a quark moves through a quark-gluon-plasma it looses energy, some of
which may go into exciting hydrodynamic modes. Certain phenomenological
models, used to explain correlations between hadronic jets in heavy ion
collisions, require tuning the relative strength of these modes in order
to fit the data. In this talk I show how one may use the gauge-string
duality to study the channels of energy loss of a heavy parton moving
through a strongly coupled conformal plasma. Implications regarding
experimental results will also be discussed.
