IAU Focus Meeting FM3:
Radio Galaxies: Resolving the AGN phenomenon
August 22 – 23, 2018
Scientific Rationale:
Radio galaxies provide excellent laboratories to probe physical aspects, unification, and the cosmic evolution of Active Galactic Nuclei (AGN). Thanks to recent multi-wavelength observations we are now able to separate many different physical components of radio galaxies through imaging and spectroscopy. Observations from the radio to the X-ray range can probe the ejection of matter into the jet and monitor decades of jet evolution. Gamma-ray observations have shown that radio galaxies are detectable up to the VHE range, despite unfavourable jet alignment. We observe radio galaxies out to redshifts larger than z=5, which makes them important cosmological probes. Planck maps have provided us with new insights into the populations of radio galaxies and their distributions in space in the 30-900 GHz range, NuSTAR provides high-quality spectra in the hard X-ray range, the EHT has begun mapping to the event horizon of the central black hole, and the SKA, E-ELT and other future telescopes will open up a new and vast discovery space. This meeting will bring together multiwavength observers and theorists to synthesize progress made over the last three years and define future directions.
Topics:
- Triggers of highly relativistic jets
- Jet collimation
- Radio galaxies as VHE photon emitters
- Knots, hotspots and other structural features
- The central engine
- Radiative versus jet mode
- Radio galaxy populations and statistics
- Origin and evolution of radio galaxies
- Interaction with the environment
- Future telescopes' view on radio galaxies
