J0107a: A Barred Spiral Dusty Star-forming Galaxy at z = 2.467 [PDF]
The Astrophysical Journal Letters, 2023 Dusty star-forming galaxies (DSFGs) are among the most massive and active star-forming galaxies during the cosmic noon. Theoretical studies have proposed various formation mechanisms of DSFGs, including major merger-driven starbursts and secular star ...

TESTING THEORIES IN BARRED-SPIRAL GALAXIES [PDF]
The Astrophysical Journal, 2011 According to one version of the recently proposed "manifold" theory that explains the origin of spirals and rings in relation to chaotic orbits, galaxies with stronger bars should have a higher spiral arms pitch angle when compared to galaxies with weaker bars.

Multicolor Photometry of Barred Spiral Galaxies [PDF]
International Astronomical Union Colloquium, 1996 B – V and R – I color maps (from CCD imagery obtained at Cerro Tololo Inter-American Observatory) of six barred spiral galaxies have been used (Horst 1992) to investigate stellar populations within the bars and nuclei. Two-color diagrams show that the distribution of pixel colors largely parallels the expected locus for normal unreddened stars. If the “

CO OBSERVATIONS OF BARRED SPIRAL GALAXIES [PDF]
Journal of The Korean Astronomical Society, 2006 We present the results of a highly sensitive ( mK rms) survey toward the central parts of 22 barred spiral galaxies in line using the NRAO 12m telescope at Kitt Peak. Seven of the target galaxies were detected in CO; NGC 3686 has been detected with CO for the first time. We estimated central CO fluxes of and molecular gas masses of for those galaxies.

Hydrodynamical simulations of the barred spiral galaxy NGC 1097 [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractNGC 1097 is a nearby barred spiral galaxy believed to be interacting with the elliptical galaxy NGC 1097A located to its northwest. It hosts a Seyfert 1 nucleus surrounded by a circumnuclear starburst ring. Two straight dust lanes connected to the ring extend almost continuously out to the bar.

Measuring Bar and Spiral Arm Pattern Speeds in MaNGA Barred Spiral Galaxies
Research Notes of the AASAbstract We measure independent pattern speeds for bar and spiral arms in 98 barred spiral galaxies with Mapping Nearby Galaxies at Apache Point Observatory data. Some galaxies exhibit statistically different pattern speeds (Ωbar ≠ Ωspiral), while others have statistically equal pattern speeds.

5.16. CO mapping of barred spiral galaxies [PDF]
Symposium - International Astronomical Union, 1998 We have made CO mapping observations of nearby barred spiral galaxies (NGC253, NGC3504, NGC4303, NGC4321, NGC6951, M83) with the Nobeyama 45-m telescope using the 2×2 SIS focal-plane array receiver. The purpose of this project is to investigate distribution and kinematics of molecular gas in barred spiral galaxies and the relation between star ...

Formation of Major Types of Galaxies Based on the Energy Circulation Theory
Reports in Advances of Physical Sciences, 2022 The standard cosmology can answer almost nothing about how the structure of a galaxy is formed. It expects a supermassive black hole at the center and dark matter in the halo to explain the circulation of stars and its velocity.
