  We study Mach shocks generated by fast partonic jets propagating through a
deconfined strongly-interacting matter. Our main goal is to take into account
different types of collective motion during the formation and evolution of this
matter. We predict a significant deformation of Mach shocks in central Au+Au
collisions at RHIC and LHC energies as compared to the case of jet propagation
in a static medium. The observed broadening of the near-side two-particle
correlations in pseudorapidity space is explained by the Bjorken-like
longitudinal expansion. Three-particle correlation measurements are proposed
for a more detailed study of the Mach shock waves.
