Title of the communication: Time-Variable Synchrotron Emission from Hydrodynamic Relativistic Jets
Preliminary abstract (12 lines max.): We present numerical simulations of the synchrotron emission from hydrodynamic relativistic jets, which can be compared directly with actual VLBI observations. The generation and evolution of shock waves along the jet are studied through the introduction of perturbations in the beam initial conditions. The association of such shocks with superluminal components in VLBI maps is analyzed through multi-epoch and multifrequency radio images obtained from the hydrodynamic simulations.
