Jet/medium interactions at large scales
  High energy emission can be produced in the interaction sites of both
galactic and extragalactic jets with the surrounding medium. We have developed
a radiative model that accounts for the continuous injection of relativistic
electrons in the forward, reverse and recollimation shocks developed in the
shell, cocoon and reconfinement interaction regions, respectively. We also
performed hydrodynamical simulations to establish the physical properties in
both galactic and extragalactic systems. The resulting non-thermal emission is
studied assuming different values for the jet power, the external mass density
and the source age for both FR I galaxies and galactic microquasars. The
obtained fluxes are compared to current instrument sensitivities at radio,
X-ray and gamma-ray bands.
