title: Sonic booms and diffusion wakes generated by a heavy quark in thermal gauge-string duality.
abstract: We evaluate the Poynting vector generated by a heavy quark moving through a thermal state of N=4 gauge theory using the gauge-string duality. A significant diffusion wake is observed as well as a Mach cone. We discuss the ratio of the energy going into sound modes to the energy coming in from the wake.
