Universal holographic hydrodynamics at finite coupling

We consider thermal plasmas in a large class of superconformal gauge theories described by a holographic dual geometry of the form AdS5xM5. In particular, we demonstrate that all of the thermodynamic properties and hydrodynamic transport parameters for a large class of superconformal gauge theories exhibit a certain universality to leading order in the inverse 't Hooft coupling and 1/Nc. In particular, we show that independent of the compactification geometry, the leading corrections are derived from the same five-dimensional effective supergravity action supplemented by a term quartic in the five-dimensional Weyl tensor
