Star formation efficiency in the Barred Spiral Galaxy NGC 4303 [PDF]
, 2010 We present new $^{12}$CO(J=1-0) observations of the barred galaxy NGC 4303 using the Nobeyama 45m telescope (NRO45) and the Combined Array for Research in Millimeter-wave Astronomy (CARMA). The H$\alpha$ images of barred spiral galaxies often show active

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.

Dense Cloud Formation and Star Formation in a Barred Galaxy [PDF]
, 2012 We investigate the properties of massive, dense clouds formed in a barred galaxy and their possible relation to star formation, performing a two-dimensional hydrodynamical simulation with the gravitational potential obtained from the 2Mass data from the ...

The Visibility of Galactic Bars and Spiral Structure At High Redshifts [PDF]
, 2002 We investigate the visibility of galactic bars and spiral structure in the distant Universe by artificially redshifting 101 B-band CCD images of local spiral galaxies from the Ohio State University Bright Spiral Galaxy Survey. Our artificially redshifted

The Astrophysical Journal Letters, 2023 A primary new capability of JWST is the ability to penetrate the dust in star-forming galaxies to identify and study the properties of young star clusters that remain embedded in dust and gas. In this Letter we combine new infrared images taken with JWST

Effects of the Central Mass Concentration on Bar Formation in Disk Galaxies
The Astrophysical Journal, 2023 While bars are common in disk galaxies, their formation conditions are not well understood. We use N -body simulations to study the formation and evolution of a bar in isolated galaxies consisting of a stellar disk, a classical bulge, and a dark halo. We

Early-growing Supermassive Black Holes Strengthen Bars and Boxy/Peanut Bulges
The Astrophysical Journal, 2023 Using N -body simulations, we explore the effects of growing a supermassive black hole (SMBH) prior to or during the formation of a stellar bar. Keeping the final mass and growth rate of the SMBH fixed, we show that if it is introduced before or while ...

Molecular Bars in Spiral Galaxies [PDF]
International Astronomical Union Colloquium, 1996 Images of molecular gas in spiral galaxies show two types of bar structure: large-scale bars, which are correlated with the presence of stellar bars, and generally follow the spiral structure, and nuclear “bars” of a few hundred parsecs in size, which show no direct correlation with the presence of a stellar bar.

GASP. XLV. Stellar Bars in Jellyfish Galaxies: Analysis of Ionized Gas and Stellar Populations
The Astrophysical Journal, 2023 Stellar bars have been found to substantially influence the properties of stellar populations in galaxies, affecting their ability to form stars. While this can be easily seen when studying galaxies in relatively isolated environments, such type of ...
