Evidence from the h3 survey that the stellar halo is entirely comprised of substructure
In the ΛCDM paradigm, the Galactic stellar halo is predicted to harbor the accreted debris of
smaller systems. To identify these systems, the H3 Spectroscopic Survey, combined with …

Reconstructing the last major merger of the Milky Way with the H3 survey
Several lines of evidence suggest that the Milky Way underwent a major merger at z∼ 2 with
the Gaia-Sausage-Enceladus (GSE) galaxy. Here we use H3 Survey data to argue that GSE …

Nitrogen enrichment and clustered star formation at the dawn of the Galaxy
Anomalously high nitrogen-to-oxygen abundance ratios [N/O] are observed in globular
clusters (GCs), among the field stars of the Milky Way (MW), and even in the gas in az≈ 11 …
