Description We require Herschel PACS and SPIRE to study the ISM and cold dust component of a gas-rich, local LIRG undergoing inside-out disk-building -- HIZOA J0836-42. Spitzer reveals this galaxy to be PDR-dominated with gas and stellar properties, as well as specific star formation, more in common with z~1 systems than local LIRGs. We see evidence of neutral gas funneling into the mid-IR star-forming disk. Our observations will provide crucial (and unique) spatial information of the ISM and cold dust that may be common to z~1 "scaled-up" disk galaxies that have large reservoirs of neutral gas that they are actively converting into stars, in an extended disk. Knowledge of the active enrichment and metamorphosis of the ISM further out in the disk due to "new" star formation will enable us to form a cohesive picture of this mechanism of star formation and the role of gas, dust and (old and new) stars. We will search for evidence of "dark" molecular hydrogen inhabiting PDRs and making a hidden (and potentially crucial) contribution to the molecular mass that fuel in these systems. We can achieve this by mapping the cool dust component across the HI disk and obtaining maps of the key cooling lines, [OI]63 and [CII]158. These data will be complementary to our broader multi-wavelength study, and motivate future planned observations that aim to address our main science goal: understanding how the components of star formation (gas, dust, stars) interact and drive the fundamental gas-to-stars evolutionary cycle for galaxies in the early universe.

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.
