Description The recent detection of large amounts of molecular gas in a sample of "normal" starforming galaxies at z~1.5 has opened up a unique window into the study of the population of galaxies that dominates the star formation rate density of the Universe. Here, we propose pioneering PACS observations of the [OI]63um emission line in the best studied sample of four such galaxies that will allow us to carry out an unprecedented characterization of their star-forming properties. We aim to characterize the warm and dense neutral gas, in combination with our CO and FIR luminosity measurements, by comparing with radiative transfer models of the interstellar medium. We will be able to study the possible relation between the [OI] line and their main physical parameters (star formation rate, star formation efficiency, masses). Herschel is the only observatory capable of performing this kind of observations, that are forbidden to ground based observatories. We request a total of 32.63h of Herschel-PACS time toprovide the last piece in the puzzle that will permit to disentangle the properties on what appear to be the progenitors of galaxies like the MilkyWay.

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.
