Parallel sessions

Studying AGN and their host galaxies in detail is a crucial step to understand the physical processes driving and regulating the growth of supermassive black holes (SMBHs), the extent and impact of their energetic feedback on the surrounding environment and thus on the star-formation activity within the host galaxy, and the overall role of AGN in shaping galaxies over cosmic time. Complementing earlier high-resolution optical, near-IR and X-ray instruments (e.g. HST, Chandra, XMM-Newton, Herschel), the unprecedented resolution and sensitivity provided by the latest generation of telescopes (e.g. VLT/MUSE, VLTI/Matisse, ALMA and the SKA precursors/pathfinders) have opened up the new regimes that have started revolutionising our view of the AGN-host galaxy interplay, leading to a clearer picture across different AGN populations/host galaxy types. A great diversity of physical phenomena have been uncovered in recent years by multi-wavelength spectroscopy and imaging, including ultra-fast outflows, warm absorbers, nuclear bars, massive multi-phase (i.e. ionized, neutral and molecular) outflows and cold gas inflows. All this provides clear evidence of a connection between the AGN fuelling/feedback processes and their host galaxy evolution, although the complexity of these phenomena, as well as the lack of statistically meaningful and conclusive studies, still leave many open questions. With the advent of next-generation telescopes (e-ROSITA, JWST, SKA, Athena. SPICA), we are at the brink of an exciting new era of discoveries in terms of AGN physics, with deep insights that will translate to the broader field of galaxy evolution. The aim of this meeting is to summarise our state of knowledge on this topic in both the nearby and high-redshift Universe. We will focus on the results obtained from the wealth of multi-wavelength observations acquired over the past few years, including complementary theoretical understanding, and look towards future perspectives in the context of forthcoming facilities. We plan to have three 90 minute blocks, which will be organised as follows: 1) AGN feeding and nuclear geometry. This session will focus on the current observational and theoretical understanding of the accretion flow onto central SMBHs and inner geometry across different AGN populations in the nearby Universe. 2) Circumnuclear environment and AGN feedback. This session will focus on the different types of AGN feedback (i.e. radiative and/or kinetic) and the impact that these can have on the circum-nuclear material and the host galaxy as a whole. 3) AGN/host galaxy interplay across cosmic times. This session will focus on studies that link AGN activity to the broader picture of galaxy evolution and the impact of AGN feedback processes on host galaxy properties over cosmic time.
