Dissecting Bar-induced Stellar Kinematics in Disk Galaxies: The Bisymmetric Model and Rotation Curve Modifications

The Astrophysical Journal
We analyze bars formed in N -body simulations to investigate two key aspects of stellar kinematic structure of barred galaxies: the angular distributions of the radial and azimuthal components of stellar velocities, and the impact of bars on rotation ...

Causal Discovery in Astrophysics: Unraveling Supermassive Black Hole and Galaxy Coevolution

The Astrophysical Journal
Correlation does not imply causation, but patterns of statistical association between variables can be exploited to infer a causal structure (even with purely observational data) with the burgeoning field of causal discovery.

The Quest for a Stable Disk

The Astrophysical Journal
The majority of disk galaxies manifest spirals and/or bars that are believed to result from dynamical instabilities. However, some galaxies have featureless disks, which are therefore inferred to be dynamically stable.
