Exploring the Milky Way stellar disk
Context. Elemental abundances in long-lived dwarf stars provide important constraints on the chemical evolution of the Galactic disk. While several large spectroscopic surveys provide abundances for vast stellar samples, small homogeneous samples remain ...

StarFlow: Leveraging Normalizing Flows for Stellar Age Estimation in SDSS-V DR19
Understanding the ages of stars is crucial for unraveling the formation history and evolution of our Galaxy. Traditional methods for estimating stellar ages from spectroscopic data often struggle with providing appropriate uncertainty estimations and are

The dynamical memory of tidal stellar streams
Context. Stellar streams offer one of the most sensitive probes of the Milky Way’s gravitational potential, as their phase-space morphology encodes both the tidal field of the host galaxy and the internal structure of their progenitors.
