| Abstract: |
An important science goal of SINGS is to develop hybrid extinction-corrected star formation rate (SFR) indices, based on the combination of infrared with optical and/or ultraviolet SFR tracers. These can provide the most robust extinction-free estimates of SFRs We present preliminary results from two studies that use the combination of Hα and the 24 μm luminosities of galaxies to derive extinction-corrected ionizing fluxes and SFRs for HII regions and galaxies, respectively. These have been applied to measure the form of the spatiallyresolved SFR vs gas density Schmidt law in M51. |
