Probing the physics of relativistic jets with observations at high-energies

Relativistic jets are associated with black hole (BH) activity spanning several orders of magnitudes in the BH mass scale, from galactic X-ray binaries to active galactic nuclei (AGNs). Their emission is a tracer of processes at work under extreme physics in terms of e.g., density, velocity,  gravitational and magnetic fields. Observations in the high-energy window are key to probe their structure and dynamics, how they interact with the environment and the coupling between the accretion and ejection processes. I will review what we can learn on jets in AGNs and microquasars, and on the systems which host them, by tracing their broadband emission. In particular, I will illustrate results on jets in misaligned AGNs observed in gamma-rays by Fermi and present our multi-wavelength campaign of observations on the jets of the microquasar XTE J1550-564. Finally, I will outline the perspectives for jets’ studies with the incoming observing facilities.
