P., Dey, A., Gänsicke, B. T., Li, T. S., Cunha, K., Zou, S., Aguilar, J. N., Ahlen, S., …Zou, H. (2023). GTC Follow-up Observations of Very Metal-poor Star Candidates from DESI. The Astrophysical journal, 957(2), Article 76. https://doi.org/10.3847/1538-4357/acfa96

The observations from the Dark Energy Spectroscopic Instrument (DESI) will significantly increase the numbers of known extremely metal-poor stars by a factor of ~10, improving the sample statistics to study the early chemical evolution of the Milky W...

Inhomogeneous Galactic chemical evolution: modelling ultra-faint dwarf galaxies of the Large Magellanic Cloud (2023)
Journal Article
Alexander, R. K., Vincenzo, F., Ji, A. P., Richstein, H., Jordan, C. J., & Gibson, B. K. (2023). Inhomogeneous Galactic chemical evolution: modelling ultra-faint dwarf galaxies of the Large Magellanic Cloud. 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...

Empirical constraints on the nucleosynthesis of nitrogen (2023)
Journal Article
Johnson, J. W., Weinberg, D. H., Vincenzo, F., Bird, J. C., & Griffith, E. J. (2023). Empirical constraints on the nucleosynthesis of nitrogen. Monthly notices of the Royal Astronomical Society, 520(1), 782-803. https://doi.org/10.1093/mnras/stad057

We derive empirical constraints on the nucleosynthetic yields of nitrogen by incorporating N enrichment into our previously developed and empirically tuned multizone galactic chemical evolution model. We adopt a metallicity-independent (‘primary’) N... Read More about Empirical constraints on the nucleosynthesis of nitrogen.
