A two-hase AGN torus as constraiined from X-ray and mid-IR observations
Abstract
To understand the active galactic nuclei (AGN) class diversity, the obscuration from some lines of sight of the inner parts of a geometrically and optically thick dusty gas torus is required. This torus is not spatially resolved even for the closest AGN. Currently, several models at mid-IR and X-ray wavelengths have been developed to describe the structure and distribution of this material. However, questions, including how the torus mid-IR and X-ray emission are related remain unanswered. Here, I will present the results obtained to compare the dust and gas distributions in a sample of nearby AGNs with NuSTAR and Spitzer spectra available. We find that the models that better reproduce the X-ray and mid-IR spectra are smooth and clumpy, respectively. These results reinforce the link between the mid-IR and X-rays in the context of the obscuring structure. Moreover, they are key for future mid-IR development, both from ground and space telescopes.
