The Metallicities of Five Small High-velocity Clouds

The Astrophysical Journal
High-velocity clouds (HVCs) are multiphase gas structures whose velocities (∣ v _LSR ∣ ≥ 100 km s ^−1 ) are too high to be explained by Galactic disk rotation.

COSMIC-L: A Photometric Catalog of Observed Stars in the Large Magellanic Cloud

The Astrophysical Journal Supplement Series
The Magellanic Clouds are two nearby dwarf irregular galaxies, the study of which can help us in understanding galaxy and stellar evolution. In particular, the Large Magellanic Cloud, the larger one, contains approximately 30 billion stars at various ...

Dual Directional Expansion of Classical Cepheids in the Small Magellanic Cloud Revealed by Gaia Data Release 3

The Astrophysical Journal Letters
We present the three-dimensional kinematics of classical Cepheids (CCs) in the Small Magellanic Cloud (SMC) using Gaia DR3 data. By crossmatching the CCs obtained from the fourth phase of the Optical Gravitational Lensing Experiment with Gaia DR3, we ...

A Comprehensive Kinematic Model of the Large Magellanic Cloud Disk from Star Clusters and Field Stars using Gaia DR3: Tracing the Disk Characteristics, Rotation, Bar, and Outliers

The Astrophysical Journal
The internal kinematics of the Large Magellanic Cloud (LMC) disk have been modeled by several studies using different tracers with varying coverage, resulting in a range of parameters. Here, we model the LMC disk using 1705 star clusters and field stars,

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.
