Recent studies reveal a huge amount of star formation in distant starburst galaxies, even at large redshifts. It is crucial to understand the nature of the star formation in these galaxies. Recent work by Gao and Solomon (2003) shows that a tight correlation exists between star formation rate, as indicated by the infrared luminosity, and the amount of dense gas, traced by the HCN 1-0 luminosity, for both normal galaxies and extreme starburst galaxies. Our work on massive, dense cores in our Galaxy indicates that this correlation continues to that much smaller scale. This correlation suggests that we can study distant star formation in terms of the properties of local, well-known star forming regions. We will present the results of our studies of Galactic regions and show the correlations that exist.
