Wijesinghe, D. B.; Hopkins, Andrew M.; Sharp, Robert; Gunawardhana, M; Brough, Sarah; Sadler, Elaine M; Driver, Simon P; Baldry, I. K.; Liske, Jochen; Tuffs, Richard J; van Kampen, E


We present self-consistent star formation rates derived through pan-spectral analysis of galaxies drawn from the Galaxy and Mass Assembly (GAMA) survey. We determine the most appropriate form of dust obscuration correction via application of a range of extinction laws drawn from the literature as applied to Hα, [O ii] and UV luminosities. These corrections are applied to a sample of 31 508 galaxies from the GAMA survey at z < 0.35. We consider several different obscuration curves, including...[Show more]
