Star Formation Activity of Barred Spiral Galaxies [PDF]
The Astrophysical Journal, 2017 Abstract We study the star formation activity of nearby galaxies with bars using a sample of late-type galaxies at and from the Sloan Digital Sky Survey.

Barred spiral galaxies in modified gravity theories [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT When bars form within galaxy formation simulations in the standard cosmological context, dynamical friction with dark matter (DM) causes them to rotate rather slowly. However, almost all observed galactic bars are fast in terms of the ratio between corotation radius and bar length.

The profiles of bars in spiral galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT We present an analysis of major-axis surface-brightness profiles of bars in a volume-limited sample of 182 barred spiral galaxies, using Spitzer 3.6 $\mu$m images. Unlike most previous studies, we use the entire bar profile, and we classify profiles into four categories.

ON THE FRACTION OF BARRED SPIRAL GALAXIES [PDF]
The Astrophysical Journal, 2010 We investigate the stellar masses of strongly barred spiral galaxies. Our analysis is based on a sample of ~14000 visually-classified nearby galaxies given in Nair & Abraham 2010(a). The fraction of barred spiral galaxies is found to be a strong function of stellar mass and star formation history, with a minimum near the characteristic mass at ...

Star Formation History in Barred Spiral Galaxies. AGN Feedback [PDF]
, 2017 We present a numerical study of the impact of AGN accretion and feedback on the star formation history of barred disc galaxies. Our goal is to determine whether the effect of feedback is positive (enhanced star formation) or negative (quenched star ...

A New Statistical Analysis of the Morphology of Spiral Galaxies [PDF]
The Astronomical JournalMorphology is the starting point for understanding galaxies. Elmegreen et al. classified spiral galaxies into flocculent, multiple-arm, and grand-design galaxies based on the regularity of their spiral arm structure.

Investigation of the Baryonic Mass Tully–Fisher Relationship for Normal and Barred Spiral Galaxies
Iraqi Journal of Science, 2023 In this study, the stellar mass M*(LB) and the atomic gas mass MHI (LB) were utilized to evaluate the baryonic mass Tully–Fisher (Mb) of disc system spiral galaxies (for normal spiral and barred spirals) and to obtain an empirical relation between ...
