Description We propose imaging with PACS (70+160 mciron) and SPIRE to ensure full resolved far-infrared (FIR) spectral energy distribution (SED) coverage of a complete equatorial sample of star-forming galaxies. This sample consists of every equatorial, face-on, star-forming galaxy of large angular extent and luminosity larger than M33. Because of their accessibility to all major facilities, particularly ALMA and the EVLA, these are the natural targets of the next generation of local galaxy studies. Herschel data are critical to estimate star formation rates, dust masses, and energetics in these galaxies and no comparable coverage of the IR SED will be possible in the foreseeable future. Without our proposed program only 13 of the 67 galaxies in this key sample will have high resolution data that span the IR peak, hindering studies of the life cycle of dust, dependence of star formation on host galaxy and local conditions, and development of robust calibrations of star formation rate tracers and the CO-to-H _2 conversion factor. Observations of this sample therefore would represent a key part of Herschel.s legacy and significantly enhance the nearby galaxy science from the next generations of northern and southern telescopes. In order to ensure maximal yield from both Herschel and ALMA-EVLA, we commit to waive our proprietary period and rapidly release our reduced data products.

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 ┬Ám range, bridging the gap between earlier infrared space missions and groundbased facilities.
