Description We propose deep PACS 100 and 160 micron imaging of three nearby,star-forming, low metallicity galaxies. These data will allow us tomake sensitive, high-resolution estimates of dust mass. We willcombine these measurements with our in-hand HI maps to measure thedust-to-gas ratio and estimate the molecular gas (H2) content in eachgalaxy. This is a challenging measurement that requires requires theresolution of PACS and good sensitivity, but H2 masses at lowmetallicity are very difficult to estimate by any other means. We willuse these H2 measurements to test recent models of H2 formation ingalaxies, improve the calibration of the CO-to-H2 conversion factor,and assess the efficiency of star formation from H2 at lowmetallicity. We will also be able to put constraints on the life cycleof dust at low metallicity from gradients in the dust-to-gasratio. These are all open questions that can best be addressed byobserving the molecular gas in low metallicity galaxies. Carrying outsuch an experiment outside the Local Group is necessary something thatonly Herschel can do.

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.
