| Description | Hierarchical models of galaxy evolution place dwarf galaxies in the role of building blocks while on the other hand alternative models to explain galaxy downsizing have also been put forth. Key to the coherent picture of galaxy evolution is a proper prescription of metal enrichment and how galaxies convert their gas into stars. Our best local universe analogs to study star formation in the early universe are star forming blue compact dwarf galaxies (BCDs) with metallicities ranging as low as 1-50 solar. How these low mass, low metallicity star forming systems form stars relatively efficiently, yet with little detectable CO emission, has been a subject of much investigation over 2 decades and still remains a mystery today. Pinning down the molecular gas reservoir of two well-known star-forming low metallicity dwarf galaxies (He2-10 and IC10) is the goal of this proposal, using the Herschel SPIRE-FTS spectrometer. |

| 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. |
