Stellar masses and star formation rates for 1M galaxies from SDSS+WISE. (2015)

Keywords : catalogs; galaxies star formation; galaxies: statistics; galaxies: stellar content; infrared: galaxies

Abstract:We combine Sloan Digitital Sky Survey (SDSS) and WISE photometry for the full SDSS spectroscopic galaxy sample, creating spectral energy distributions (SEDs) that cover {lambda}=0.4-22{mu}m for an unprecedentedly large and comprehensive sample of 858365 present-epoch galaxies. Using MAGPHYS (da Cunha+ 2008MNRAS.388.1595D), we then simultaneously and consistently model both the attenuated stellar SED and the dust emission at 12 and 22{mu}m, producing robust new calibrations for monochromatic mid-IR star formation rate (SFR) proxies. These modeling results provide the first mid-IR-based view of the bimodality in star formation activity among galaxies, exhibiting the sequence of star-forming galaxies ("main sequence") with a slope ...(more)

We use the SDSS spectroscopic galaxy sample as compiled in the New York University Value-added Galaxy Catalog (NYU-VAGC; Blanton+ 2005AJ....129.2562B; Adelman-McCarthy+ 2008, II/282, superseded by II/294; Padmanabhan+ 2008ApJ...674.1217P), which contains 858365 galaxies with reliable redshift measurements. The SDSS parent sample is cross-matched with the AllWISE source catalog (II/328); see section 2 for further explanations.
