Query: Development of relativistic shock waves in viscous gluon matter   To investigate the formation and the propagation of relativistic shock waves
in viscous gluon matter we solve the relativistic Riemann problem using a
microscopic parton cascade. We demonstrate the transition from ideal to viscous
shock waves by varying the shear viscosity to entropy density ratio $\eta/s$.
We show that an $\eta/s$ ratio larger than 0.2 prevents the development of
well-defined shock waves on time scales typical for ultrarelativistic heavy-ion
collisions. These findings are confirmed by viscous hydrodynamic calculations.
