Context:

Active Galactic Nuclei are sources in which the accretion of matter onto a central object and the related ejection of accreting material are most spectacular. Relativistic collimated jets are observed from the radio to the gamma ray bands, and the study of winds and outflows has been progressing noticeably in the last few years, thanks to new spectroscopic observations in the UV, optical and X-ray bands.
The physical link between the processes of accretion and ejection seems also promising to understand the mechanisms regulating the gas infall, and to determine the kinetic and physical properties of the expelled matter.
This event is focused on investigating accretion and ejection phenomena that occur at all scales, especially based on recent observations at all wavelengths and their interpretation.

Topics:

Accretion:

disks
flows
rates/types
obscuration
redshift evolution

Outflows and winds:
observational evidence
dynamics
origin

Jets:
life-cycle:
what triggers them
how long they live

dependence of their properties on the nature of the central engine
dynamics:
launching
collimation
propagation and evolution over orders of magnitude in physical scale
populations of AGN jets
Impact on environment and on galaxy evolution
