Time evolution of the global A_V for the static and dynamic dust models in our Milky Way-like galaxy simulation is shown in the left and right panels, respectively. In each panel, solid lines indicate attenuation including scattering (with-scattering), while dashed lines represent attenuation neglecting scattering (no-scattering). The inclination angle is color-coded. The bottom panels show the ratio between the with-scattering and no-scattering attenuation. This ratio quantifies the impact of scattering on the total attenuation, with lower values indicating a stronger contribution from scattering.
