Meeting Location: Noto, Sicily, Italy
The Perseus cluster has recently been the stage of some ground-breaking
discoveries:
on ultra-fine linear scales, space-VLBI has revealed fundamental
details of the jet launching mechanism,
on large scales, and at superb energy resolution, Hitomi has revealed
surprising details about the gas dynamics, shaking our current understanding
of the cool core phenomenon,
in gamma rays of high and very high energy, dramatic activity with
extremely short time scales has been reported both in NGC 1275 and IC 310.
The importance and timeliness of discussing these and other topics, including
feedback, is enhanced by the many developments recently achieved also in the
fields of theory of accretion and particle acceleration, as well as to the
great improvement in performance and accuracy of numerical simulations and
imaging techniques.
The organizers will gather multi-wavelength observers and theoreticians,
experts from the event horizon out to the Megaparsec scales, encouraging
interactions and discussion. Participation of qualified scientists with limited
means of support, e.g., colleagues from economically less privileged countries
and young scientists, will be facilitated thanks to IAU Travel Grants.
Key topics will include:
- approaching the Schwarzschild radius: methods to measure BH mass and spin
- BH magnetosphere & sphere of gravitational influence
- hot vs cold accretion
- magneto-hydrodynamical processes in disks and jets
- jet production, collimation, and acceleration mechanisms
- HE emission: site and mechanisms, particle acceleration, leptonic vs hadronic processes
- jet-medium interaction on galactic and cluster scales
- thermal and non-thermal emission in galaxy clusters
- turbulence, gas heating and cooling
- AGN winds and BH-galaxy coevolution
