Query: The Influence of Helical Magnetic Fields in the Dynamics and Emission of
  Relativistic Jets   We present numerical relativistic magnetohydrodynamic and emission
simulations aimed to study the role played by the magnetic field in the
dynamics and emission of relativistic jets in Active Galactic Nuclei. We focus
our analysis on the study of the emission from recollimation shocks since they
may provide an interpretation for the stationary components seen at
parsec-scales in multiple sources. We show that the relative brightness of the
knots associated with the recollimation shocks decreases with increasing jet
magnetization, suggesting that jets presenting stationary components may have a
relatively weak magnetization, with magnetic fields of the order of
equipartition or below.
