The Milky Way’s Rowdy Neighbors: The Effects of the Large Magellanic Cloud and Sagittarius Dwarf on the Milky Way Disk

The Astrophysical Journal
The Milky Way (MW) is a barred spiral galaxy shaped by tidal interactions with its satellites. The Large Magellanic Cloud (LMC) and the Sagittarius dwarf galaxy (Sgr) are the dominant influences at the present day. This paper presents a suite of four 10 ^

The kinematics and structure of the neutral hydrogen in the barred spiral galaxy NGC 3359.

, 1982
The barred spiral galaxy NGC 3359 has been observed with the three-element line interferometer of the National Radio Astronomy Observatory. An angular resolution of 42'' x 31'' was achieved with a velocity resolution of 24.5 km/s.

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.

Thick disk and pseudobulge formation in a clump cluster

EPJ Web of Conferences, 2012
Bulges in spiral galaxies have been supposed to be classified into two types: classical bulges or pseudobulges. Classical bulges are thought to form by galactic merger with bursty star formation, whereas pseudobulges are suggested to form by secular ...

Dynamical models - The barred spiral galaxy NGC 1300

, 1989
The results of hydrodynamical model calculations for the classic SBb(s) system NGC 1300 are presented and compared to high-resolution H I observations reported by England (1989).

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.

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.
