The galaxy spectra we observe are attenuated by dust, produced in galaxies themselves. However, in studies of galaxy evolution, a genuine galaxy spectrum without attenuation is often needed, and the evolution of the attenuation curve is also fundamental for the investigation for the evolution of dust in galaxies. We show one of the important aspects of dust attenuation, the infrared excessultraviolet spectral slope (IRX-β) relation by using the data from MUSYC and GOODS-Herschel projects. We found that the IRX-β relation does not show significant evolution from z=0 to z3, with a very large scatter.
