2019A&A...621A..51H Comprehensive comparison of models for spectral energy distributions from 0.1 micron to 1 mm of nearby star-forming galaxies Hunt, L.

We have fit the far-ultraviolet (FUV) to sub-millimeter (850 micron) spectral energy distributions (SEDs) of the 61 galaxies from the Key Insights on Nearby Galaxies: A Far-Infrared Survey with Herschel (KINGFISH). The fitting has been performed using three models: the Code for Investigating GALaxy Evolution (CIGALE), the GRAphite-SILicate approach (GRASIL), and the Multiwavelength Analysis of Galaxy PHYSical properties (MAGPHYS). We have analyzed the results of the three codes in terms of the SED shapes, and by comparing the derived quantities with simple "recipes" for stellar mass (M_star_), star-formation rate (SFR), dust mass (M_dust_), and monochromatic luminosities. Although the algorithms rely on different assumptions for star-formation history, dust attenuation and dust reprocessing, they all well approximate the observed SEDs and are in generally good agreement for the associated quantities. However, the three codes show very different behavior in the mid-infrared regime: in the 5-10 micron region dominated by PAH emission, and also between 25 and 70 micron where there are no observational constraints for the KINGFISH sample. We find that different algorithms give discordant SFR estimates for galaxies with low specific SFR, and that the standard recipes for calculating FUV absorption overestimate the extinction compared to the SED-fitting results. Results also suggest that assuming a "standard" constant stellar mass-to-light ratio overestimates M_star_ relative to the SED fitting, and we provide new SED-based formulations for estimating M_star_ from WISE W1 (3.4 micron) luminosities and colors. From a principal component analysis of M_star_, SFR, M_dust_, and O/H, we reproduce previous scaling relations among M_star_, SFR, and O/H, and find that M_dust_ can be predicted to within ~0.3 dex using only M_star_ and SFR. Key words: galaxies: fundamental parameters, galaxies: star formation, galaxies: ISM, galaxies: spiral, infrared: galaxies, ultraviolet: galaxies
