| Description | Dust affects the cooling cycle in the ISM and this affects the ability of a galaxyto form cold, dense clouds that can form stars. Thus, the low dust content of dwarfirregular galaxies should have consequences to the star formation process,but just what is the connection? We propose to use SPIRE and PACS to mapthe FIR dust continuum emission of 5 dwarf galaxies, specifically extendingthe sample of nearby resolved dwarfs being observed under KP/GT/OT1 programs to 5x lower metallicities. We will construct spatially resolved FIR spectral energydistributions and determine the dust components. That, in combination withour exquisite HI maps and comprehensive images tracing star formation overthree age scales, will allow us to examine the relationship between the dust content, gas, and star formation in dwarf irregular galaxies as a function of metallicity. These data will be unique in the wealth of information they will provide about dust at very low metallicities, and this will be important for understanding the formation of stars 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 µm range, bridging the gap between earlier infrared space missions and groundbased facilities. |
