Abstract: Describing the Universe in its early stages requires obtaining knowledge about the various components in distant galaxies (stars, gas, dust). This work aims to further constrain the relationship between the ultraviolet dust attenuation and stellar mass, as well as the evolution of the dust attenuation with redshift, by creating a three dimensional model for the dust attenuation, which uses these two galactic parameters (redshift and stellar mass). By combining data from different literature sources, we were able to compile a data set comprised of estimates of photometric redshift, stellar mass and dust attenuation calculated by the infrared excess (IRX) method, i.e. by converting the ratio of the infrared-to-ultraviolet luminosity of galaxies to ultraviolet dust attenuation. Using this result, we will be able to model and predict what the emission of galaxies at high redshifts is. This information will be useful to understand and interpret the data that the ELT will collect, especially the first imaging instruments MICADO and METIS.
