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.
