High-dipole moment molecules such as HCN and CS trace much denser molecular gas than that of CO (the total molecular gas mass tracer). HCN strongly and linearly correlates with the far-infrared (FIR) emission for essential all star-forming systems near and far (Gao and Solomon 2004; Gao et al. 2007). CS observations in galaxies further demonstrate similarly tight correlations. Such tight linear FIR - dense molecular gas correlation suggests that the star formation rate depends essentially linearly upon the mass of dense molecular gas and the tiny dense cores inside the giant molecular clouds might be the basic units of massive star formation in galaxies. The order-of-magnitude increases in both the spatial resolution and sensitivity of the ALMA will reveal many such dense cores in local galaxies and revolutionize our understanding of the formation of massive stars in galaxies.
