Accreting supermassive black holes in the X-ray band

X-ray emission is an ubiquitous property of active galactic nuclei and, being produced within a few gravitational radii from the accreting supermassive black hole, it can provide fundamental information about the characteristics of the accretion flow, and about the structure and geometry of the circumnuclear material.In my talk I will review some of the most recent findings obtained by the BAT AGN Spectroscopic Survey (BASS -, the largest multi-wavelength survey of hard X-ray (>10 keV) selected AGN, with particular emphasis on the properties of the gas and dust located in the inner parsecs of these systems. I will also discuss the first results obtained with a newly developed simulation platform, RefleX, which allows to reproduce absorption and reflection of X-ray radiation by quasi-arbitrary geometries.
