Abstract
We report the discovery of a well-defined correlation between B-band face-on central optical depth due to dust and the stellar mass surface density of nearby spiral galaxies. This relation was derived from a sample of spiral galaxies
taken from the Galaxy and Mass Assembly (GAMA) survey, which were detected in the FIR/submm
in the Herschel -ATLAS science demonstration phase field. Using a quantitative analysis of the NUV
attenuation-inclination relation for complete samples of GAMA spirals categorized according to stellar
mass surface density we demonstrate that this correlation can be used to statistically correct for dust
attenuation purely on the basis of optical photometry and SĀ“ersic-profile morphological fits.
