Cooling flows in X-ray bright clusters of galaxies can deposit large amounts of cooled intracluster gas on the galaxies at their centers. A wide variety of UV/optical/IR signatures of deposition have been found, including evidence for cooled gas and dust and for star formation at rates of ~10-300 M_sun/yr. Recent Chandra and XMM-Newton soft X-ray spectroscopy shows that the energy balance of the intracluster gas is strongly affected by heating from a highly efficient feedback mechanism, which is not yet identified. We propose to obtain Spitzer/IRS mid-IR spectral maps to explore the deposition process in five archetypal cluster cooling flows. Our specific interests include assessing the relation of the dust to the cooling flow and obtaining greatly improved estimates of the star formation rates for comparison to the deposition rates. The basic mechanisms of cooling and energy feedback which can be studied in the mid-IR in these systems are relevant to a wide range of galaxy astrophysics.
