| Title: | A high spatial resolution study of the nearby, heavily obscured nuclei |

Abstract
We propose to continue our investigation of the dust properties of heavily obscured galaxy nuclei by making spatially-resolved spectroscopic observations of nuclei with deep silicate absorption features in the N-band. We will investigate the depths and profiles of the silicate absorption band and search for extended structures that arise from dust heated in the narrow line region and/or in cold dusty circumnuclear material. The nuclear emission from several of the bgalaxies has been resolved by Gemini, giving the opportunity to investigate the spatial dependence of different dust components and give clues to the properties of dust in the nuclei of AGN.
