Talk Active Galactic Nuclei – from ISCO to CGM and from cosmic dawn to the present day Active Galactic Nuclei – from ISCO to CGM and from cosmic dawn to the present day

Description

A surprising result from mid-infrared (MIR) interferometry of nearby active galactic nuclei (AGN) is that a major fraction of the parsec-scale dust emission is elongated in the polar direction perpendicular to the accretion plane. This has spurred a new paradigm for the nuclear structure, where a dusty conical wind carries a substantial outflow of material into the interstellar medium. I will present JWST-centric multi-wavelength studies of nearby AGN with the aim of identifying and understanding polar emission and its relationship to gaseous outflows. I will outline the modern methods we employ to overcome the complex nature of our datasets and the first characterisation of resolved dust continuum emission on 100 pc scales in a local Seyfert galaxies. With JWST, we are able to measure the size and shape of the polar dust, explore its composition, and directly trace its interaction with neighbouring gas, zooming in on the sites of feedback in action.
