The VISCACHA Survey XV: Tracing the 3D Structure and Chemical Evolution of the Outskirts of the Large Magellanic Cloud from Star Clusters

The Astrophysical Journal
The Large Magellanic Cloud (LMC) is the Milky Way’s most massive satellite. Its interactions with the Small Magellanic Cloud are expected to leave imprints on its structure and evolution. In this work, we use the LMC outer star cluster population to seek

Oxygen Isotopes Reveal Low-mass Star Dominance in the Small Magellanic Cloud

The Astrophysical Journal
Oxygen isotope abundances and their ratios are fingerprints of stellar evolution, and therefore provide a powerful tool in tracing the enrichment history of galaxies.

A Galactic Transformation—Understanding the SMC’s Structural and Kinematic Disequilibrium

The Astrophysical Journal
The SMC is in disequilibrium. Gas line-of-sight (LOS) velocity maps show a gradient of 60–100 km s ^−1 , generally interpreted as a rotating gas disk consistent with the Tully–Fisher relation. Yet, the stars don’t show rotation.

The Distant Milky Way Halo from the Southern Hemisphere: Characterization of the LMC-induced Dynamical Friction Wake

The Astrophysical Journal
The infall of the Large Magellanic Cloud (LMC) into the Milky Way’s halo impacts the distribution of stars and dark matter (DM) in our Galaxy. Mapping the observational consequences of this encounter can inform us about the properties of both galaxies ...
