The Clearing Timescale for Infrared-selected Star Clusters in M83 with HST

The Astrophysical Journal Letters
We present an analysis of Hubble Space Telescope data from Wide Field Camera 3 (WFC3)/Ultraviolet Imaging Spectrometer, WFC3/IR, and the Advanced Camera for Surveys, investigating the young stellar cluster (YSC) population in the face-on spiral galaxy ...

Formation Mechanisms for Spirals in Barred Galaxies

, 2000
We consider a scenario of formation of the spiral structure in barred galaxies. This scenario includes the new non-resonant mechanism of elongation of spirals, due to the characteristic behaviour of the gravitational potential beyond the principal spiral arms.

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.

Enhanced star formation: The importance of bars in spiral galaxies [PDF]

It was found that among an IR luminous subset of nearby spiral galaxies, nearly all of the systems with IRAS colors and luminosities indicative of enhanced star formation are barred.

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).

Comparison of Bar Formation Mechanisms. II. Does a Tidally Induced Bar Grow Faster than an Internally Developed Bar?

The Astrophysical Journal
Bar structures can form internally due to the instability of their host galaxies or externally due to perturbations from other galaxies. We systematically quantify the growth timescales ( τ _bar ) of bars formed through these two mechanisms with a series
