FOR5195: Relativistic Jets in Active Galaxies

Matthias Kadler
JMU Würzburg

In the process of mass accretion onto a supermassive black hole (SMBH), active galactic nuclei (AGN) can form powerful collimated relativistic outflows, called jets, which emit brightly across the electromagnetic spectrum up to the highest energies. Jets have been associated with very-high energy neutrinos and are among the most likely candidates for the long sought-after sources of ultrahigh-energy cosmic rays. In this talk, I will present how we are addressing open questions in AGN jet research within a coordinated network of research groups across Germany, the DFG Research Unit FOR5195: How are relativistic jets launched from the vicinity of supermassive black holes? How are they accelerated and collimated? Which radiative and dynamic processes govern the high-energy emission of AGN jets and what are AGN jets composed of? How do AGN jets interact with their host galaxy? How does AGN feedback heat the ICM and which are the observational signatures? To address these questions, we combine theory, modeling and interpretation in the light of new observational data collected by the latest astronomical facilities at all observational wavelengths.
