Title: High Spatial Resolution MIR Spectroscopy of Seyfert Nuclei

Abstract: An obscuring dusty torus is a key ingredient of active galactic nuclei (AGN). However, despite much work, the intricate structure and characteristics of the torus remain unconstrained. Implementing two independent methods of determining the torus viewing angle---optical spectropolarimetry and clumpy torus model fittings of mid-IR spectra---we find the two techniques produce consistent results, but only when the IR data is dominated by the AGN. We request Gemini observations of 5 sources whose large-aperture Spitzer observations are contaminated by the contribution from star formation.
