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 ...

The CO-to-H2 Conversion Factor in the Barred Spiral Galaxy M83 [PDF]

The Astrophysical Journal
We analyze the CO-to-H _2 conversion factor ( α _CO ) in the nearby barred spiral galaxy M83. We present new H i observations from the VLA and single-dish GBT in the disk of the galaxy, and combine them with maps of CO(1-0) integrated intensity and dust ...

Systematic Variations of CO J = 2−1/1–0 Ratio and Their Implications in The Nearby Barred Spiral Galaxy M83

Astrophysical Journal, 2020
We present spatial variations of the CO J = 2−1/1–0 line ratio ( ) in the barred spiral galaxy M83 using Total Power Array (single-dish telescopes) data from the Atacama Large Millimeter/submillimeter Array.

Barred spiral galaxies in modified gravity theories [PDF]

, 2021
When bars form within galaxy formation simulations in the standard cosmological context, dynamical friction with dark matter (DM) causes them to rotate rather slowly.

GMC evolution in a barred spiral galaxy with star formation and thermal feedback [PDF]

, 2016
We explore the impact of star formation and thermal stellar feedback on the giant molecular cloud (GMC) population forming in a M83-type barred spiral galaxy.

THE CENTRAL REGION OF THE BARRED SPIRAL GALAXY NGC 1097 PROBED BY AKARI NEAR-INFRARED SPECTROSCOPY [PDF]

, 2012
With the Infrared Camera on board AKARI, we carried out near-infrared (2.5–5.0 μm) spectroscopy of the central kiloparsec region of the barred spiral galaxy, NGC 1097, categorized as Seyfert 1 with a circumnuclear starburst ring.

ADF22-WEB: A giant barred spiral starburst galaxy in the z = 3.1 SSA22 protocluster core [PDF]

Nippon Tenmon Gakkai obun kenkyu hokoku
In the present-day universe, the most massive galaxies are ellipticals located in the cores of galaxy clusters, harboring the heaviest super-massive black holes (SMBHs).

A New Statistical Analysis of the Morphology of Spiral Galaxies [PDF]

The Astronomical Journal
Morphology 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.
