The restless nature of AGNs

bh_artistIt is widely accepted that variability provides important information on the nature of the emission mechanisms and the geometry of the central source in Active Galactic Nuclei. This is an exciting time in the field of AGN variability, due to the wealth of new results produced in the last few years. This conference intends to focus on radio-quiet sources, discussing our current understanding of the central source variability across the IR, optical, and UV regimes up to hard X-rays, and the clues that variability provides about the physics and structure of the AGN phenomena. The contributions are intended to address the problem of AGN variability both from the observational and theoretical point of view, on short and long time scales, presenting results and expectations from wide-field/deep surveys, pointed observations, ground-based and space observatories.

Topics:

•X-ray flux and spectral variability

•Outflows and SED variability

•The UV-X ray connection

•Variability on the optical band: reverberation, the continuum and the full sky surveys

•AGN variability analysis methods

•Variability in MHD simulations of accretion flows
