“…Generally speaking, AGN being very broad-band emitters over the whole electromagnetic spectrum, very promising synergies can be anticipated with most space and ground-based large infrastructures of the domain such as LOFAR, SKA, GAIA, JWST, and ELT. Based on the results obtained so far by the MOJAVE project and similar VLBI searches [193,194,195], one might expect that regular VLBI mapping at radio frequencies, coordinated with VHE campaigns, will significantly constrain the global picture of the AGN central core at the subpc scale, linking the mechanism of jet formation, the ejection of radio knots, the growth of shocks and turbulence together with the localization, geometry and dynamics of the VHE emitting zones. It should also solve the persistent paradox of non-detection of superluminal velocities in the VLBI maps of VHE blazars while extremely large bulk Lorentz factors are needed for explaining the fluxes and variability [196].…”

Active Galactic Nuclei (hereafter AGN) produce powerful outflows which offer excellent conditions for efficient particle acceleration in internal and external shocks, turbulence, and magnetic reconnection events. The jets as well as particle accelerating regions close to the supermassive black holes (hereafter SMBH) at the intersection of plasma inflows and outflows, can produce readily detectable very high energy gamma-ray emission. As of now, more than 45 AGN including 41 blazars and 4 radiogalaxies have been detected by the present ground-based gamma-ray telescopes, which represents more than one third of the cosmic sources detected so far in the VHE gamma-ray regime. The future Cherenkov Telescope Array (CTA) should boost the sample of AGN detected in the VHE range by about one order of magnitude, shedding new light on AGN population studies, and AGN classification and unification schemes. CTA will be a unique tool to scrutinize the extreme high-energy tail of accelerated particles in SMBH environments, to revisit the central engines and their associated relativistic jets, and to study the particle acceleration and emission mechanisms, particularly exploring the missing link between accretion physics, SMBH magnetospheres and jet formation. Monitoring of distant AGN will be an extremely rewarding observing program which will inform us about the inner workings and evolution of AGN. Furthermore these AGN are bright beacons of gamma-rays which will allow us to constrain the extragalactic infrared and optical backgrounds as well as the intergalactic magnetic field, and will enable tests of quantum gravity and other "exotic" phenomena.
