New paper: Connection between early and local galaxies

Earlier this month, our paper (arXiv) on the chemical enrichment of the first galaxies and their connection to local ultra-faint dwarf galaxies was accepted to MNRAS. This paper was led by JHU postdoctoral researcher Lauren Corlies. We compared the average metallicities of both simulated and actual galaxies to determine how and when they were enriched, in particular if Population III (metal-free) stars imprinted on them. We also explored an analytical model of metal enrichment (i.e. blastwave evolution) that matched the simulation data to a reasonable degree. We found that the simulation produced metallicity distributions in single galaxies that are narrower than the data, and future work is needed to address this inconsistency in simulations of low-mass galaxies.
