The origin of dust and its effect on the atomic and molecular phase in galaxies is still uncertain. This is important as dust plays a crucial role in providing opacity during the star formation process and is hypothesised to be a catalyst in the conversion of atomic to molecular hydrogen. We have selected two BLAST galaxies NGC 1097 and NGC 1512 as they are low inclination spiral galaxies with prominent gas and dust features, at a distance of 16.9 and 10.4 Mpc respectively[2]. A large set of complementary data has been collected for both targets including SPITZER infra-red, GALEX UV and VLA HI data. Measurements of the molecular gas spatial distribution combined with other datasets will allow us to investigate the relationship between the dust, gas and star formation in different galactic environments (from the bulge to the spiral arms). This project provides a unique opportunity to gain an insight into what Herschel will produce. We are requesting 70.8 hours of Mopra time in average weather to map molecular gas in two of the BLAST nearby galaxies by measuring the CO(1-0) emission line.
