Feedback from active galactic nuclei (AGN), where a fraction of the luminous energy output is injected into the host galaxy, driving multiphase outflows, is a necessary ingredient in galaxy evolution models, where it explains the mass function, colours and star formation histories of galaxies. This feedback almost certainly manifests in the form of ubiquitous jets and outflows. They are observed on all spatial scales, from the X-ray to the radio band and from the nearby to the very distant (>13 Gyr ago) Universe. They often have mass and energy flow rates large enough to quench star formation and further supermassive black hole growth in their host galaxies. Despite abundant observational data and numerous simulations ranging from the nuclear to cosmological scales, there is no unified physical model explaining how the outflows are launched, evolve across the various spatial and temporal scales, and affect the host galaxy evolution. Both simulations and observations continue to improve, with new and upcoming modelling projects (IllustrisTNG, Romulus, FLAMINGO, FIRE-2) and observing facilities (JWST, ELT, ALMA, LOFAR, SKA) offering unprecedented insights into the properties and evolution of jets and outflows. This special session will bring together researchers investigating all types of AGN outflows, both with observations and numerical simulations, to share the recent progress and identify ways to connect these often disparate sub-fields to advance our understanding of the connection between supermassive black holes and their host galaxies.

List of topics:

• Manifestations of AGN feedback on small (sub-parsec) scales, such as UFOs, jets, etc.
• Manifestations of AGN feedback on large (parsec to hundreds of kiloparsec) scales, such as outflows, shocks and jet cocoons.
• Theoretical models of AGN-driven outflows on galaxy, cluster and cosmological scales and comparison of their general properties and population statistics to observations.
