Secular Evolution Via Bar-Driven Gas Inflow: Results from BIMA SONG

, 2005
We present an analysis of the molecular gas distributions in the 29 barred and 15 unbarred spirals in BIMA SONG. For CO-bright galaxies, we confirm the conclusion by Sakamoto et al.

Orbital Support and Evolution of CX/OX Structures in Boxy/Peanut Bars

The Astrophysical Journal
Barred galaxies exhibit boxy/peanut or X-shapes (BP/X) protruding from their disks in edge-on views. Two types of BP/X morphologies exist depending on whether the X-wings meet at the center (CX) or are off-centered (OX).

The Hidden Story of Chemical Evolution in Local Star-forming Nuclear Rings

The Astrophysical Journal
A Very Large Telescope/MUSE population synthesis study of metallicities in the nuclear star-forming rings of four disk galaxies (NGC 613, NGC 1097, NGC 3351, NGC 7552) is presented.

Ring or No Ring—Revisiting the Multiphase Nuclear Environment in M31

The Astrophysical Journal
Nuclear rings, prevalent in barred galaxies, are essential to understanding gas transport toward galactic nuclei. However, the peculiar nuclear ring in our neighboring galaxy M31 remains poorly understood.

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 TYPHOON Stellar Population Synthesis Survey. II. Pushing Full Spectral Fitting to the Limit in the Nearby Grand Design Barred Spiral M83

The Astrophysical Journal
We apply population synthesis techniques to analyze TYPHOON long slit spectra of the starburst barred spiral galaxy M83. The analysis covers a central square of 5′ side length.
