Special Session Topics

To facilitate interaction between prospective proposers of special topical sessions, we have opened a dedicated forum where anyone can propose and share their ideas. The forum is open to everyone, but the link is only provided to those who have submitted a registration. 




==== ACCEPTED SPECIAL SESSIONS AND LEAD-OFF TALKS (9 TOTAL, 10 minute slots each during the session) ==== 

A. The Fuzzy Future of Radio Galaxy Classification - Larry RUDNICK, and TBD (co-conveners)
After 5 decades, it’s time to revisit how we classify radio galaxies. The science demands a more sophisticated approach, and the massive new surveys provide the opportunity to do a better job. With the advent of citizen science projects and machine learning, and a new databases that could contain different types of morphological information, the community needs to decide the proper balance between fixed naming, and more flexible systems where objective criteria are used to define samples as needed. We will discuss the main issues/challenges facing us, and facilitate a discussion about the best path forward.

B. Multi-wavelength data - Barbara BALMAVERDE, and TBD (co-conveners)

In the last two decades a suite of ground and space based observations has been built for the 3C at all accessible wavelengths with all major observing facilities from HST (with images from the UV to the IR and including also emission line imaging), to Chandra, Spitzer, Herschel, JVLA, as well as ground-based integral field optical spectra (e.g. with Muse). Each electromagnetic bands offer a different and complementary prospective of the radio galaxies phenomenon and allow the investigation of different scientific questions.

C. Polarimetry - Eric PERLMAN, and TBD (co-conveners)

Polarimetry is useful for AGN and radio galaxies in several ways. It allows one to probe the structure of the central engine from other angles, by looking for scattered light.  It also allows one to probe the ordering of the magnetic field in the emitting and scattering regions.  It therefore is a key to AGN physics in a number of regions, both within the central engine as well as within the extended jets.  It allows us to test particle acceleration models as well as geometrical and unification models.  A special session would allow us to focus on these ideas.
