  We develop the linear equations that describe graviton perturbations of
AdS_5-Schwarzschild generated by a string trailing behind an external quark
moving with constant velocity. Solving these equations allows us to evaluate
the stress tensor in the boundary gauge theory. Components of the stress tensor
exhibit directional structures in Fourier space at both large and small
momentum. We comment on the possible relevance of our results to relativistic
heavy ion collisions.
