The innermost regions of Active Galactic Nuclei - from radio to X-rays

Abstract

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.
