### Description

The formation of Mach cones is studied in a full $(3+1)$-dimensional setup of ultrarelativistic heavy-ion collisions, considering a transverse and longitudinal expanding medium at RHIC energies. For smooth initial conditions and central collisions the jet-medium interaction is investigated using high-energy jets and various values of the shear viscosity over entropy density ratio, $\eta/s$. For small viscosities, the formation of Mach cones is proven, while for larger viscosities the characteristic structures smear out and vanish eventually. The formation of a double-peak structure both in a single and a multiple jet event is discussed.
