The Innermost Regions of Active Galactic Nuclei – From Radio to X-rays

Active galactic nuclei 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, a new radio interferometer planned for the next decade, and the oncoming x-ray and gamma ray missions.
