The Impacts of Bars, Spirals, and Bulge Size on Gas-phase Metallicity Gradients in MaNGA Galaxies

The Astrophysical Journal
As galaxies evolve over time, the orbits of their constituent stars are expected to change in size and shape, moving stars away from their birth radius. Radial gas flows are also expected. Spiral arms and bars in galaxies are predicted to help drive this

Is NGC 4631 a barred spiral galaxy?

The Astronomical Journal, 1991
High- and low-dispersion optical spectra of the giant H II region CM 67 near the center of the edge-on galaxy NGC 4631 have been obtained. Comparisons are made with radio observations to suggest the existence of a large bar in NGC 4631. Region CM 67 is shown to coincide in position with the easternmost peak of a triple radio-continuum source.

In silico, in vitro and ex vivo characterization of cystic fibrosis transmembrane conductance regulator pathogenic variants localized in the fourth intracellular loop and their rescue by modulators

British Journal of Pharmacology, Volume 182, Issue 24, Page 6063-6080, December 2025.
Background and Purpose Cystic fibrosis (CF) is due to loss‐of‐function variants of the CF transmembrane conductance regulator (CFTR) channel. The most effective treatment for people with CF carrying the F508del mutation is the triple combination of elexacaftor–tezacaftor–ivacaftor (ETI).

Dark Gaps and Resonances in Barred Galaxies

The Astrophysical Journal
Dark gaps, low surface brightness regions along the bar minor axis, are expected to form as a consequence of secular evolution in barred galaxies. Although several studies have proposed links between dark gap locations and dynamical resonances, the ...

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

Stellar Populations, Bars and Secular Evolution in Late-Type Galaxies [PDF]

, 2000
We have done a robust statistical analysis of UBV color profiles of 257 Sbc barred and unbarred galaxies. We found that there is an excess of barred galaxies among the objects with null or positive (bluish inward) color gradients, which seems to indicate

The HST/ACS Coma Cluster Survey. VIII. Barred Disk Galaxies In The Core Of The Coma Cluster [PDF]

, 2012
We use high-resolution (similar to 0.'' 1) F814W Advanced Camera for Surveys (ACS) images from the Hubble Space Telescope ACS Treasury survey of the Coma cluster at z similar to 0.02 to study bars in massive disk galaxies (S0s), as well as low-mass dwarf

Somato‐Cognitive Action Network in Focal Dystonia

Movement Disorders, Volume 40, Issue 11, Page 2331-2343, November 2025.
Abstract Background The central pathology causing idiopathic focal dystonia remains unclear. The recently identified somato‐cognitive action network (SCAN) has been implicated. Objective We tested whether the effector‐agnostic SCAN may constitute a central pathology shared across dystonia subtypes, whereas the effector‐specific regions in the primary ...

Conditions for Bar Formation in Bulgeless Disk Galaxies

The Astrophysical Journal
While bars are commonly observed in disk galaxies, the precise conditions governing their formation remain incompletely understood. To investigate these conditions, we perform a suite of N -body simulations of bulgeless disk galaxies with stellar masses ...

The impact of bars on the mid-infrared dust emission of spiral galaxies: global and circumnuclear properties [PDF]

, 2001
We study the mid-infrared properties of a sample of 69 nearby spiral galaxies, selected to avoid Seyfert activity contributing a significant fraction of the central energetics, or strong tidal interaction, and to have normal infrared luminosities.
