Radiative transfer in disc galaxies II - The influence of scattering and geometry on the attenuation curve

Abstract

We investigate the influence of scattering and geometry on the attenuation curve in disc galaxies. We investigate both qualitatively and quantitatively which errors are made by either neglecting or approximating scattering, and which uncertainties are introduced due to a simplification of the star-dust geometry. We find that the magnitude of these errors depends on the inclination of the galaxy, and in particular that for face-on galaxies, the errors due to an improper treatment of scattering dominate those due to an imprecise star-dust geometry. Therefore we argue that in all methods which aim at determining the opacity of disc galaxies, scattering should be taken into account in a proper way.
