Abstract (from CDS):

begin{HTML}Star formation rates (<I>SFR</I>s) obtained via extinction-corrected Hα are compared to dense gas, as traced by <sup>12</sup>CO (J = 3–2) (J = 3-2) emission at the centers of nearby galaxies, observed with the ASTE telescope. It is found that, although many of the observed positions are dusty, and therefore heavily absorbed at Hα the <I>SFR</I> shows a striking correlation with dense gas in the form of the Schmidt law with an index of 1.0. The correlation is also compared between gas traced by <sup>12</sup>CO (J = 1-0) and the application of an Hα extinction correction. We find that dense gas produces a far-better correlation with <I>SFR</I> in view of the surface density values.
