UNIONS: The Ultraviolet Near-infrared Optical Northern Survey

The Astronomical Journal
The Ultraviolet Near-Infrared Optical Northern Survey (UNIONS) is a “collaboration of collaborations” that is using the Canada–France–Hawai’i Telescope, the Pan-STARRS telescopes, and the Subaru Observatory to obtain ugriz images of a core survey region ...

In Pursuit of Galactic Archaeology

, 2019
The next decade affords tremendous opportunity to achieve the goals of Galactic archaeology. That is, to reconstruct the evolutionary narrative of the Milky Way, based on the empirical data that describes its current morphological, dynamical, temporal and chemical structures. Here, we describe the path to achieving this goal.

Chemical Abundances in the Nuclear Star Cluster of the Milky Way: Alpha-element Trends and Their Similarities with the Inner Bulge

The Astrophysical Journal
Chemical characterization of the Galactic center is essential for understanding its formation and structural evolution. Trends of alpha ( α ) elements, such as magnesium, silicon, and calcium, serve as powerful diagnostic tools, offering insights into ...

Watching Our Galaxy Grow Up: The Mass and Color Evolution of the Milky Way

The Astrophysical Journal
Using our rich observations within the Milky Way to better understand galaxy evolution requires understanding what the Milky Way looks like “as a galaxy”—that is, its “true” shape and abundance profiles (unskewed by observational biases), signatures of ...

The evolution of the Galactic Disk in a New Era of Galactic Archaeology

Dans l'univers actuel, une étoile a plus de chances de se trouver dans une galaxie semblable à la Voie lactée (VL) que dans tout autre type de galaxies, ce qui fait de notre galaxie un laboratoire idéal pour étudier les processus généraux qui dominent la formation et l'évolution de ces systèmes. La composante stellaire la plus massive de la Voie lactée

MEASNet. I. A Model for Barium Star Identification and s-process Abundance Estimation from LAMOST DR10 Low-resolution Survey

The Astrophysical Journal
Barium stars are peculiar stars with enhanced slow neutron capture process ( s -process) elements. Abundance analysis of them aids in better understanding the chemical evolution of the Milky Way. In this paper, we introduce a data-driven method named the
