Summary Diffusion wake dominates the freezeout distribution in a static
medium
Different impact of pQCD and AdS/CFT source terms
Radial flow affects the results by deflecting Mach cones and interacting with the Diffusion wake
Diffusion wake contribution depends on path length of the jet Away-side peaks: non-central jets have to be included Pure energy deposition: No conical structure in expanding
medium
always created if dM/dx > threshold
clear difference between static & expanding medium
effect of the Neck region
non-linear hydrodynamics is fundamental for quantitative studies of jets in medium
