Origin Of Red Sequence Barred Spiral Galaxies [PDF]

, 2022
Spiral galaxies contain spiral arms that are sites of ongoing star formation, typically making these galaxies appear blue in color. Several studies, however, have recently found that a small fraction of cluster spiral galaxies (~10%) appear red in color.

The characteristic polarized radio continuum distribution of cluster spiral galaxies [PDF]

, 2007
Deep observations are presented of the 6 cm polarized radio continuum emission of 8 Virgo spiral galaxies. All galaxies show strongly asymmetric distributions of polarized intensity with elongated ridges located in the outer galactic disk. These features

100 Proof: H i Observations of 100 Nearby Dwarf Galaxies with the 100 m Green Bank Telescope

The Astronomical Journal
We describe the results of observations with the 100 m Robert C. Byrd Green Bank Telescope in the H i line of 105 nearby dwarf galaxies, 60 of which were discovered recently in the DESI Legacy Imaging Surveys.

Galaxy Spiral Arm Count versus Concentration and Mass: A First Look with Euclid

The Astrophysical Journal
Using catalogued information from Euclid Quick Data Release 1, we compare two-armed and three-armed spiral galaxies as classified by the Euclid Zoobot software.

Gas minor-axis velocity gradients in early-type spiral galaxies

, 2003
We measured a remarkable gas velocity gradient along the minor axis of 5 early-type spiral galaxies. This phenomenon suggests the presence of a kinematically-decoupled component in orthogonal rotation with respect to the galaxy disk.

Star Formation in the Lopsided Galaxy Arp 291

The Astrophysical Journal
We have investigated the star formation process taking place in the lopsided galaxy Arp 291, based on narrowband images in the H α , [N ii ] λ 6583, and [O iii ] λ 5007 emission lines, obtained using the modern tunable photometer MaNGaL at the Caucasus ...

Azimuthal offsets in spiral arms of nearby galaxies

Spiral arms play a central role in disc galaxies, but their dynamical nature remains a long-standing open question. Azimuthal offsets between molecular gas and star formation are expected if gas crosses spiral arms, as predicted by quasi-stationary ...

Spiral Structure Properties, Dynamics, and Evolution in Milky Way–mass Galaxy Simulations

The Astrophysical Journal
The structure of spiral galaxies is essential to understanding the dynamics and evolution of disk galaxies; however, the precise nature of spiral arms remains uncertain.

Do spiral arms enhance star formation efficiency?

Spiral arms, as those of our own Milky Way, are some of the most spectacular features in disc galaxies. It has been argued that star formation should proceed more efficiently in spiral arms as a result of gas compression.
