Presentation #100.33 in the session AGN.
I will present new state-of-the-art physical modeling with spherical, toroidal, and non-toroidal geometries for one of the X-ray brightest Compton-thin Sy 2 AGN in the local universe. Its presumed moderate obscuration is paramount for constraining both distant-matter properties and emission from the accretion disk, imprinted on narrow and broad Fe K emission, and associated continua, respectively. Broadband X-ray coverage and high spectral resolution in the ~6 keV region allow us to obtain excellent fits for all three geometries. For the first time we demonstrate that a very simple model, consisting of a uniform, fully covering, spherical, solar Fe abundance geometry with narrow-line Fe Kα emission provides an excellent fit to the high-energy data. All models confirm the Compton-thin nature of NGC 4388 both in the line-of-sight and globally. Further, we combine relativistic and non-relativistic models and obtain limits to relativistic accretion-disk emission. Our results show that any such contribution to the net spectrum is at the level of ≲2% .
