Early r-process Enrichment and Hierarchical Assembly Across the Sagittarius Dwarf Galaxy

open access: yesThe Astronomical Journal
Dwarf galaxies like Sagittarius (Sgr) provide a unique window into the early stages of galactic chemical evolution, particularly through their metal-poor stars.

Disentangling γ − β: The Fourth-order Velocity Moments Based on Spherical Jeans Analysis

open access: yesThe Astrophysical Journal
Distinguishing a core and a cusp within dark matter halos is complexified by the existence of mass-anisotropy degeneracy, where various combinations of velocity anisotropy ( β ) and inner density slope ( γ ) yield similar observational signatures.
