Galaxy-Absorber Association in the Epoch of Reionization: Galactic Population Luminosity Distribution for Different Absorbers at 10 ≤ z ≤ 5.5

We present our analysis of metal contributions from galaxies as observed in quasar absorption line spectra from 10 ≥ z ≥ 5.5 during the end of the Epoch of Reionization (EoR). This was done with particle tracking done in-parallel in the latest Technicolor Dawn run and then linking absorbers to potential host galaxies in post-processing. When we look at all the species in our test (CII, CIV, SiII, SiIV, MgII, and OI) we see that all galaxies contribute roughly equally to each absorber. We then did the analysis while splitting the absorbers into stronger (≥ 0.01 Å) and weaker absorbers and we see that galaxies still equally contribute to both the population of stronger and weaker absorbers. We also do not see any relation between the absorber strength and the stellar mass of the contributing galaxy. From these results, we conclude that we cannot reject most metals being synthesized and ejected from less luminous, less massive galaxies if one assumes current UVLF and stellar mass function assuming flat ΛCDM with implications that most metal absorbers may be associated with galaxies currently below the observational limits of even JWST.
