Abstract
Observations of Active Galactic Nuclei (AGN) have revealed that the power emitted by these sources is partially obscured by material residing in our line of sight, within the inner tens of parsecs of the central engine. This obscuring material will influence the AGN and our observations, and the study of its properties is fundamental for an unbiased understanding of AGN physics. In this talk, I will present a study of the obscuration properties of a large sample of X-ray selected AGN, and characterise how gas and dust can be linked with the physical properties of the central source. I will also describe the balance between AGN radiation pressure and gravitational potential, and how it can influence the structure of the host galaxy.
