Abstract
We compute the energy and momentum deposited by a fast-moving parton in a quark-gluon plasma using linear viscous hydrodynamics with an energy loss per unit length profile proportional to the path length and with different values of the shear-viscosity to entropy-density ratio. We show that when varying these parameters, the transverse modes dominate over the longitudinal ones and thus energy and momentum is preferentially deposited along the head-shock, as in the case of a constant energy loss per unit length profile and the lowest value for the shear-viscosity to entropy-density ratio.
