SDSS-IV MaNGA: Stellar Population Gradients Within Barred Galaxies

, 2019
Bars in galaxies are thought to stimulate both inflow of material and radial mixing along them. Observational evidence for this mixing has been inconclusive so far however, limiting the evaluation of the impact of bars on galaxy evolution.

Reduction of the Bar Fraction in Paired Galaxies in the SDSS

The Astrophysical Journal
We investigate the bar fraction in galaxy pairs from the Sloan Digital Sky Survey to assess how galaxy interactions affect bar structures. Compared to isolated galaxies, close pairs exhibit a significantly reduced bar fraction at projected separations ...

Origin Of Red Sequence Barred Spiral Galaxies

, 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 Role of Spiral Arms in Galaxies

The Astrophysical Journal
We test the influence of spiral arms on the star formation activity of disk galaxies by constructing and fitting multiwavelength spectral energy distributions for the two nearby spiral galaxies NGC 628 and NGC 4321, at a spatial scale of 1–1.5 kpc ...

Are spiral galaxies heavy smokers?

, 1990
The dustiness of spiral galaxies is discussed. Starburst galaxies and the shortage of truly bright spiral galaxies is cited as evidence that spiral galaxies are far dustier than has been thought.

Aperture corrections for disk galaxy properties derived from the CALIFA survey: Balmer emission lines in spiral galaxies [PDF]

, 2013
This work investigates the effect of the aperture size on derived galaxy properties for which we have spatially-resolved optical spectra.We focus on some indicators of star formation activity and dust attenuation for spiral galaxies that have been widely
