NGC 1300 Dynamics: III. Orbital analysis

, 2010
We present the orbital analysis of four response models, that succeed in reproducing morphological features of NGC 1300. Two of them assume a planar (2D) geometry with $\Omega_p$=22 and 16 \ksk respectively.

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.

Importance of Initial Condition on Bar Secular Evolution: Role of Halo Angular Momentum Distribution Discontinuity

The Astrophysical Journal
The dark matter halo properties, for example, mass, spin, and concentration, play a significant role in the formation and evolution of bars in disk galaxies.

Physical Properties of Gas Departing from Circular Rotation at 50 pc Scales Using the PHANGS-MUSE Galaxies

The Astronomical Journal
Noncircular (NC) motions have been observed across various spatial scales in disk galaxies, yet the physical properties of the gas involved in these motions remain poorly constrained.

ALMA-LEGUS. I. The Influence of Galaxy Morphology on Molecular Cloud Properties

The Astrophysical Journal
We present a comparative study of the molecular gas in two galaxies from the Legacy ExtraGalactic UV Survey (LEGUS) sample: barred spiral NGC 1313 and flocculent spiral NGC 7793.
