Scientific paper

We propose to obtain low and high resolution IR spectra of a sample of nearby powerful radio galaxies that show fast (>1000 km/s) outflows of neutral hydrogen (HI) gas. These HI outflows are most likely driven by jet-ISM interactions and can reach outflow rates comparable to those of starburst driven outflows in Ultra Luminous Infra-Red Galaxies -- they are therefore likely the missing component of AGN feedback in the nearby universe. Our proposed Spitzer observations are aimed to study in detail the H2 emission lines in these powerful radio galaxies in order to inventory the warm molecular gas in these galaxies, find evidence for jet-induced shocks in the ISM and estimate outflow rates of molecular gas. This should allow us to verify whether jet-cloud interactions are indeed the main driving mechanism of these massive outflows and to get a better idea about the total mass outflow rates in these nearby radio galaxies.
