Description
In recent years our comprehension of the physical processes shaping the dynamics of relativistic jets and their emission has been revitalized by advances in both observational and theoretical tools. On the observational side, new radio and high-energy data, together with measurement of the polarization in the X-ray band by IXPE, provide a growing (albeit not undisputed) support to the scenario based on shocks as the main sites for particle acceleration. Advanced numerical simulations allow us to better describe jet production, acceleration and propagation, including the effects on the environment. On the small scale, detailed simulations probe the microphysics of particle acceleration with unprecedented detail. In the talk I will review some of these progresses, also mentioning the potential multi messenger role of jets from AGNs.
