Monthly notices of the Royal Astronomical Society, 522(4), 5415-5433. https://doi.org/10.1093/mnras/stad1312

Ultra-faint dwarf galaxies (UFDs) are among the oldest and most metal-poor galaxies in the cosmos, observed to contain no gas and a high dark matter mass fraction. Understanding the chemical abundance dispersion in such extreme environments could she...
