Spitzer mid-infrared spectral maps of the neary galaxy M58 reveal that the physical conditionsof the interstellar medium in molecular gas and star-forming regions are impactedby AGN-feedback. In particular, the strong H_2 extended emission in this galaxy appears to trace a large mass of jet-shocked molecular gas.We developed a flexible spectral-cube fitting tool to fit the IR spectra of galaxies. We are using this tool to search for extended H_2 emission in nearby galaxies so we vcan study the effects of the AGN feedback on molecular gas and how this affects the star formation process in galaxy bulges.
