Comparison of physical properties of observed LCEs (magenta points) and the simulated galaxies (black points). Here we show the stellar mass (top left), gas metallicity (oxygen abundances, i.e., 12 + log10(O/H) for observed galaxies, top middle), galaxy radius (galaxy virial radius for simulated ones and exponential disk scale length for observed ones, top right) and SFR (SFR₁₀) as a function of their escaping Lyα luminosities. The Lyα luminosities of the SPHINX galaxies do not scale with stellar masses, metallicities, or galaxy sizes, whereas they do correlate with recent star formation, as expected. Top-right panel: we show the SFR (SFR₁₀ for simulated galaxies) as a function of the stellar mass of galaxies. The properties of the observed LCEs are listed in Table 1, and more details can be found in their corresponding reference papers.
