Bar-driven Transport of Molecular Gas in Spiral Galaxies: Observational Evidence [PDF]

arXiv, 1999
The NRO-OVRO CO imaging survey showed that molecular gas was more concentrated to the central kiloparsec in barred spiral galaxies than in their unbarred counterparts. The result provided not only evidence for bar-driven gas transport but also estimates on the mean rate of gas transfer and lower limits to the lifetime of bars.

ALMA-LEGUS. II. The Influence of Subgalactic Environments on Molecular Cloud Properties

The Astrophysical Journal
We compare the molecular cloud properties in subgalactic regions of two galaxies, barred spiral NGC 1313, which is forming many massive clusters, and flocculent spiral NGC 7793, which is forming significantly fewer massive clusters despite having a ...

Optical long slit velocities and a combined optical and H i velocity field for the barred spiral galaxy NGC 1365

, 1996
Optical emission line velocities in NGC 1365 are presented along 35 slit positions, of which 18 have not been published earlier. Diagrams of emission line velocities as function of distance along the slits are presented, and separate velocity fields are ...

Mapping Obscured Star Formation in the Host Galaxy of FRB 20201124A

The Astrophysical Journal
We present high-resolution 1.5–6 GHz Karl G. Jansky Very Large Array and Hubble Space Telescope (HST) optical and infrared observations of the extremely active repeating fast radio burst (FRB) FRB 20201124A and its barred spiral host galaxy. We constrain

Stellar Bars Form Dark Matter Counterparts in TNG50

The Astrophysical Journal
Dark matter (DM) bars that shadow stellar bars have been previously shown to form in idealized simulations of isolated disk galaxies, but have yet to be studied in a fully cosmological context.

Hidden Gems on a Ring: Infant Massive Clusters and Their Formation Timeline Unveiled by ALMA, HST, and JWST in NGC 3351

The Astrophysical Journal
We use 0.1″ observations from the Atacama Large Millimeter Array (ALMA), Hubble Space Telescope (HST), and JWST to study young massive clusters (YMCs) in their embedded “infant” phase across the central starburst ring in NGC 3351.
