  • We update the spectral modeling code MAGPHYS to include a 2175Å absorption feature in its UV-tonear-IR dust attenuation prescription. This allows us to determine the strength of this feature and the shape of the dust attenuation curve in ∼5000 star-forming galaxies at 0.1 < z . 3 in the COSMOS field. We find that a 2175Å absorption feature of ∼1/3 the strength of that in the Milky Way is required for models to minimize residuals. We characterize the total effective dust attenuation curves as a… CONTINUE READING
