A new technique to constrain torus parameters using X-ray and mid-IR simultaneous fit

In order to understand the diversity of classes observed in active galactic nuclei (AGN), a geometrically and optically thick torus of gas and dust is required to obscure the central engine depending on the line of sight to the observer. In this talk, I present a new technique that explores the hypothesis that the structure producing the continuum emission at mid-IR and the reflection component at X-ray are the same. If this is the case, they can be used together to better constrain the physical parameters of the torus. Our technique consists on a simultaneous fitting of Spitzer and NuSTAR spectra using mid-IR and X-ray models available. During this talk, I will also show the first results obtained when applying our technique to the nearby type-2 active nucleus IC 5063. Finally, I will show the first results when we applied this technique a sample of AGNs.
