Andreea Petric (Gemini) The ISM of Local Luminous Infrared Galaxies and PG QSOs I will present an analysis of of 248 luminous infrared galaxies (LIRGs) nuclei which comprise the Great Observatories All-sky LIRG Survey (GOALS) observed with the Infrared Spectrograph on Spitzer in the rest-frame wavelength range between 5 and 38 microns. I will present and compare several diagnostics effective at isolating the Active Galactic Nuclei (AGN) contribution to the Mid-infrared (MIR) (fAGN) emission using These diagnostics suggest that between 10% and 13% of local LIRGs are AGN dominated in the MIR and that AGNs contribute 12% of the total bolometric luminosity of the entire sample. Warm H2 is detected in at least one transition in 40% of sources. I find that the H2 scales with aromatic band emission and [Si II]. The range of total H2 to IR ratios in LIRGs is wider than in ULIRGs but similar to normal galaxies. We detect H2 resolved emission and compare it with similar findings in radio galaxies and nearby mergers. I will also present high sensitivity observations taken with Herschel to measure the cold dust content in a sample of 87 nearby QSOs chosen from the optically luminous broad-line PG QSO sample. These data are combined with NIR and MIR measurements from 2MASS and WISE to assess the aggregate dust properties in those AGN, and compare them to those of nearby early type galaxies.
