Resumen:
Jets are found in a variety of astrophysical sources. In all the cases
the jet propagates with a supersonic velocity through the external
medium, which can be inhomogeneous, and inhomogeneities could penetrate
into the jet. The interaction of the jet material with an obstacle
produces a bow-like shock within the jet in which particles can be
accelerated up to relativistic energies and emit high-energy photons.
In this work, we explore the active galactic nuclei scenario, focusing
on the dynamical and radiative consequences of the interaction at
different jet heights. We find that the produced high-energy emission
could be detectable by the current γ-ray telescopes. In general, the
jet-clump interactions are a possible mechanism to produce (steady or
flaring) high-energy emission in many astrophysical sources in which
jets are present.
