The high angular resolution and sensitivity of the Spitzer instruments enable us to undertake a study of low luminosity AGN and warm dust in a sample of 103 "normal" elliptical and lenticular galaxies for which we have measured the X-ray luminosity of the AGN and the extent and mass of the hot X-ray gas with Chandra observations. With the Spitzer and Chandra observations, supplemented by radio fluxes and optical spectroscopy, we will determine the contribution of IR and X-ray emission to the bolometric luminosity of low luminosity AGN as a function of luminosity and test if the spectral energy distribution is consistent with that predicted by RIAF models. We will use the IRAC and MIPS colors to characterize and help classify the low luminosity AGN. We will determine if the luminosity of the AGN is affected by either the presence of cool IR emitting material or the cooling rate of the hot gas. We will compare the rate at which cooling gas forms new stars with the amount of recent star formation estimated from Spitzer images. We also will map the distribution of warm dust and compare that with the mass and distribution of hot gas to study the coexistence of hot gas and dust in galaxy cores. In addition to this archival proposal to analyze the 45 early-type galaxies, we also have proposed Spitzer IRAC and MIPS observations of 58 galaxies (C. Jones - PI) to complete the Chandra-Spitzer sample of 103 early type galaxies.
