Star formation in nearby galaxies
Listed in IVOA Registry (Virtual Observatory)
We present multiwavelength global star formation rate (SFR) estimates for 326 galaxies from the Star Formation Reference Survey in order to determine the mutual scatter and range of validity of different indicators.
Description
The widely used empirical SFR recipes based on 1.4GHz continuum, 8.0um polycyclic aromatic hydrocarbons (PAHs), and a combination of far-infrared (FIR) plus ultraviolet (UV) emission are mutually consistent with scatter of <~0.3dex.
The scatter is even smaller, <~0.24dex, in the intermediate luminosity range 9.3<log(L_60um_/L_{sun}_)<10.7. The data prefer a non-linear relation between 1.4GHz luminosity and other SFR measures. PAH luminosity underestimates SFR for galaxies with strong UV emission.

A bolometric extinction correction to far-UV luminosity yields SFR within 0.2dex of the total SFR estimate, but extinction corrections based on UV spectral slope or nuclear Balmer decrement give SFRs that may differ from the total SFR by up to 2dex. However, for the minority of galaxies with UV luminosity >5x10^9^L_{sun}_ or with implied far-UV extinction <1mag, the UV spectral slope gives extinction corrections with 0.22dex uncertainty.
