AbstractWith ISO, Spitzer and Herschel, we have made great strides toward understanding the heating and cooling in Luminous Infrared Galaxies (LIRGs): those sources with L(sub IR) greater than or equal to 10(exp 11) solar luminosity whose bolometric energy output is dominated by re-radiated infrared emission from dust, which were first discovered with IRAS. We have quantified the relative importance of Active Galactic Nuclei (AGN) and starbursts to statistically significant samples of low-z LIRGs, and have used the MIR dust and gas diagnostics to measure the power sources in samples of SMGs and QSOs out to z approximately 4 with Spitzer/IRS. Recently, we have measured the bright FIR fine-structure cooling lines in large numbers of local LIRGs and starburst galaxies with Herschel, establishing key scaling relationships between the central starbursts, AGN, and the FIR emission lines. In addition, fast, massive outflows of cold molecular gas have been detected which provide a direct window on the interaction of the central source and the molecular gas reservoir. SPICA, with it's large, cold primary and suite of sensitive instruments promises to once more revolutionize our picture of the infrared Universe, carrying forward the work we have done with Spitzer and Herschel to fainter and more distant galaxies, building large samples of LIRGs at high-z, and reaching the brightest sources at the earliest epochs.
