Effects of Halo Spin on the Formation and Evolution of Bars in Disk Galaxies

The Astrophysical Journal
The spin of dark halos has been shown to significantly affect bar formation and evolution in disk galaxies. To understand the physical role of halo spin in bar formation, we run N -body simulations of isolated, Milky Way–sized galaxies by varying the ...

Automated Detection of Galactic Rings from Sloan Digital Sky Survey Images

The Astrophysical Journal
Morphological features in galaxies—like spiral arms, bars, rings, and tidal tails, etc.—carry information about their structure, origin, and evolution.

High-velocity Molecular Clouds in M83

The Astrophysical Journal
High-velocity clouds (HVCs), which are gas clouds moving at high velocity relative to the galactic disk, may play a critical role in galaxy evolution, potentially supplying gas to the disk and triggering star formation.

Tracing Coherent Gas Structures in the Central Region of the Starburst Galaxy NGC 253. II. Gas Excitation and Star Formation

The Astrophysical Journal
Molecular gas in the central region of the starburst galaxy NGC 253 is complicated because of the combination of different gas kinematics, including stellar feedback, noncircular motions, and magnetic activity.
