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.
