Monthly Notices of the Royal Astronomical Society, 494(4), 5636–56511365-2966https://doi.org/10.1093/mnras/staa1044http://hdl.handle.net/10566/5865We study the photometric properties and sizes of the reionization-epoch galaxies in high-resolution SIMBA cosmological hydrodynamical simulations with box sizes of [25,50]h−1Mpc⁠. Assuming various attenuation laws, we compute photometry by extincting each star particle’s spectrum using the line-of-sight gas metal column density. The predicted ultraviolet luminosity function (UVLF) generally agrees with observations at z = 6, owing to a partial cancellation between the high metallicities of the simulated galaxies and lower dust-to-metal ratios.enGalaxies: evolutionGalaxies: formationGalaxies: high-redshiftGalaxies: photometryGalaxies: stellar contentArticle
