The improved resolution and sensitivity of the new Spitzer Space Telescope widens the stage for the discovery of previously unknown AGN and precision photometry of known AGN by spatially resolving and removing the host galaxy light. Due to dust obscuration and low activity, many AGN can remain undetected. We use color profiles and modeling of the galaxies in question in order to isolate and photometer point source nuclei, and we use previous classifications to study the spectral energy distributions as a function of AGN class. Seyfert, LINER, and H II nuclei can be clearly separated using IR flux ratios, demonstrating the potential of the Spitzer to classify AGN in the IR.
