[X/Fe] Marks the Spot: Mapping Chemical Azimuthal Variations in the Galactic Disk with APOGEE

The Astrophysical Journal
Chemical cartography of the Galactic disk provides insights into its structure and assembly history over cosmic time. In this work, we use chemical cartography to explore chemical gradients and azimuthal substructure in the Milky Way disk with giant ...

An Analytic Model for Stellar Metallicity Gradient Residuals in Cold, Phase-mixed Galactic Disks

The Astrophysical Journal Letters
The distribution of stellar metallicities over phase space in galactic disks is sculpted by both star formation and secular orbital transport processes.

Cosmological Simulations of Stellar Halos with Gaia Sausage–Enceladus Analogs: Two Sausages, One Bun?

The Astrophysical Journal
Observations of the Milky Way’s stellar halo find that it is predominantly comprised of a radially biased population of stars, dubbed the Gaia Sausage–Enceladus, or GSE.

Dynamical Origins of Azimuthal Metallicity Variations in the Galactic Disk: Insights from Kinematic Ridges with Gaia

The Astrophysical Journal
Kinematic and spectroscopic studies in the past few years have revealed coherent azimuthal metallicity variations across the disk of the Milky Way (MW) that may be the result of dynamical process associated with nonaxisymmetric features of the Galaxy. At
