| Description | We propose a spatially-resolved far-infrared spectroscopic survey of a sample of 23 nuclear and extranuclear regions within 22 nearby galaxies, selected to represent the broadest range of key physical properties, including luminosity, gas and stellar mass, star-formation density, and infrared activity. Combined with our wealth of ancillary imaging and spatially resolved spectroscopy from the heritage of SINGS/KINGFISH and related surveys (ultraviolet, optical, infrared, low-J CO, and radio), the proposed SPIRE/FTS dataset will provide key insights into the processes that shape the interstellar medium and govern star formation. Detection of the continuum emission from large grains over 200-650 microns will place new constraints on the long-wavelength behavior of dust emissivity. The richness of the emission line spectrum in this wavelength regime will allow us to quantify the excitation conditions of CO over a wide range of environments, and to characterize the physical properties of warm and dense gas within galaxies on kiloparsec scales, interpreting these properties using models of photo- and X-ray-dissociated gas, and comparing directly with resolved tracers of star formation, heating, and AGN activity. With capabilities unmatched by existing or planned ground- or space-based facilities, SPIRE/FTS mapping of a well-studied sample of nearby galaxies will serve as a crucial, unique, and lasting foundation for interpreting ALMA observations of galaxies at high redshift. |

| Mission Description | Herschel was launched on 14 May 2009! It is the fourth cornerstone mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities. |
