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 ...

On wave dark matter in spiral and barred galaxies [PDF]
Journal of Cosmology and Astroparticle Physics, 2015 We recover spiral and barred spiral patterns in disk galaxy simulations with a Wave Dark Matter (WDM) background (also known as Scalar Field Dark Matter (SFDM), Ultra-Light Axion (ULA) dark matter, and Bose-Einstein Condensate (BEC) dark matter). Here we show how the interaction between a baryonic disk and its Dark Matter Halo triggers the formation of

The Formation of Nuclear Rings in Barred Spiral Galaxies [PDF]
The Astrophysical Journal, 2003 To be published in the Astrophysical Journal in January 2003. Due to the size limitations of astro-ph, no figures are in the astro-ph version.

Dynamical rules for barred spiral galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 1985 Des integrations numeriques des orbites-2D demontrent que la famille principale d'orbites periodiques dans les forts potentiels barres est la famille parallele prograde. Toutes les autres familles ont des distributions de la densite des orbites qui sont incompatibles avec le potentiel impose.

Symposium - International Astronomical Union, 1970 We point out some properties of barred spiral galaxies which are important for the theory of their formation and spiral structure, and describe some theoretical work on the dynamics of these systems.

Effect of bars on evolution of SDSS spiral galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We explore the significance of bars in triggering central star formation (SF) and active galactic nucleus (AGN) activity for spiral galaxy evolution using a volume-limited sample with 0.020 < z < 0.055, Mr < −19.5, and σ > 70 km s−1 selected from Sloan Digital Sky Survey Data Release 7.

Gaseous Vortices in Barred Spiral Galaxies [PDF]
The Astrophysical Journal, 2000 Simulations of the gas flow in a variety of two-dimensional barred spiral galaxies have shown that vortices in the gas appear, when viewed from above, in the corotation frame of the bar. These low-density vortices generally appear at or near the L4 and L5 Lagrangian points.
