abstract
We study the effects of expansion and viscous corrections on the hydrodynamical medium response to a high energy jet parton. More specifically, using a semi-analytical Gubser solution to relativistic fluid dynamics, modifications to the formed Mach cone, diffusive wake, and the momentum flow of the medium response along and perpendicular to the jet particle, are analyzed mode-by-mode. This should provide intuition and guidance for analyses of the experimentally measured jet sub-structure in heavy-ion collisions.

Giving wake to energy-energy correlators: Hydrodynamic response on the celestial sphere
The medium response contribution to the jet energy-energy correlator scales as dSigma/dtheta proportional to theta at small angles and can qualitatively reproduce the large-angle enhancement seen in PbPb-to-pp EEC measurements.
