Discovery of a Barred-spiral Galaxy at zspec = 3.16. II. The Star Formation History

The Astrophysical Journal
We present a detailed analysis of a massive barred galaxy at z _spec  = 3.1591 using deep multiband imaging from the Hubble Space Telescope (HST) and JWST.

NOEMA3D: Resolving radial gas flows in disk galaxies at z ~ 1.1–1.6 with high-resolution CO observations

Astronomy & Astrophysics
We present NOEMA3D, a unique high-resolution study of purely molecular gas kinematics at z ~ 1.1 to 1.6, providing a dedicated view of cold gas dynamics at the late stages of the peak epoch of cosmic star formation. Using deep (≳20 h on source per target)

Barred Galaxies in MaNGA: Stellar Mass Dependence and Black Hole Growth

The Astrophysical Journal
This study investigates the role of internal structures, such as stellar bars and active galactic nuclei (AGN), in shaping galaxy evolution using 7408 galaxies (2641 barred) from the Sloan Digital Sky Survey IV Mapping Nearby Galaxies at Apache Point ...

The building blocks of 3D models of barred galaxies

Astronomy & Astrophysics
We conducted an orbital study of Milky Way-like models of barred galaxies of three degrees of freedom in order to detect the orbits that support different structures of the galaxies, such as rings and spiral arms.

Duration and properties of the embedded phase of star formation in 37 nearby galaxies from PHANGS-JWST

Astronomy & Astrophysics
Light reprocessed by dust grains emitting in the infrared enables the study of the physics at play in dusty embedded regions, where ultraviolet and optical wavelengths are attenuated.

Galactic Bars Are Already Mature at Cosmic Noon: Bar Strength and Flatness at z ∼ 1.5

The Astrophysical Journal
In this work, we explore the nature of z  > 1 galactic bars. Once thought to be highly transient, our results demonstrate otherwise. Our sample consists of nine massive (>10 ^10.5 M _⊙ ) star-forming barred-spiral galaxies at z _spec  ∼ 1.5.

Kinematics in the central kiloparsec of spiral galaxies [PDF]

, 2001
Results from kinematic observations of the central regions of spiral galaxies are reviewed, with particular emphasis on starburst and AGN hosts. While morphological studies lead to important insights, a more complete understanding of the physical ...

Luminosities of barred and unbarred S0 galaxies

, 2012
Lenticular galaxies with M B < -21.5 are almost exclusively unbarred, whereas both barred and unbarred objects occur at fainter luminosity levels. This effect is observed both for objects classified in blue light, and for those that were classified in ...
