Empirical determination of the shape of dust attenuation curves in star-forming galaxies

Vivienne Wild, Stephane Charlot, Jarle Brinchmann et al. ADS

There are a variety of dust extinction and attenuation laws used in the literature. Here we measure empirically for the first time the effective attenuation law for light coming from star-forming galaxies. We show how the wavelength dependence varies with galaxy properties such as whether there is a dominant bulge, specific star formation and inclination.
