  Active Galactic Nuclei (AGN) can be probed by at different regions of the
electromagnetic spectrum: e.g., radio observations reveal the nature of their
relativistic jets and their magnetic fields, and complementarily, X-ray
observations give insight into the changes in the accretion disk flows. Here we
present an overview over the AGN research and results from an ongoing
multi-band campaign on the active galaxy NGC1052. Beyond these studies, we
address the latest technical developments and its impact in the AGN field: the
Square Kilometre Array (SKA), a new radio interferometer planned for the next
decade, and the oncoming X-ray and gamma-ray missions.
