H-alpha kinematics of S4G spiral galaxies-II. Data description and non-circular motions [PDF]

, 2015
We present a kinematical study of 29 spiral galaxies included in the Spitzer Survey of Stellar Structure in Galaxies, using Halpha Fabry-Perot data obtained with the Galaxy Halpha Fabry-Perot System instrument at the William Herschel Telescope in La ...

UV–Vis Spectra of Carbonic Acid: Rationalizing Experimental Redshifts between Monomer and Bulk based on (H2CO3)n Calculations

ChemPhysChem, EarlyView.
In bulk carbonic acid (e.g., in interstellar icy dust grains) cluster formation produces two distinct UV‐Vis spectral features redshifted by ≈2 eV (25 nm) and by ≈5 eV (80 nm) compared to gas phase single molecule carbonic acid 's adiabatic ionization energy. Theory and experiment were used to investigate the origin of these shifts.

Bar Diagnostics in Edge-On Spiral Galaxies. I. The Periodic Orbits Approach

, 1999
We develop diagnostics to detect the presence and orientation of a bar in an edge-on disk, using its kinematical signature in the position-velocity diagram (PVD) of a spiral galaxy observed edge-on.

Somato‐Cognitive Action Network in Focal Dystonia

Movement Disorders, EarlyView.
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 ...

The Illustris Simulation: Supermassive Black Hole - Galaxy Connection Beyond the Bulge

, 2017
We study the spiral arm morphology of a sample of the local spiral galaxies in the Illustris simulation and explore the supermassive black hole - galaxy connection beyond the bulge (e.g., spiral arm pitch angle, total stellar mass, dark matter mass, and ...

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, EarlyView.
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).

Spiral Structure and Galaxy Environment

, 2002
Among 330 normal spirals of types Sa-Sc the fraction of objects exhibiting ``ring'', ``intermediate'' and ``spiral'' arm varieties does not correlated with environment.

What determines the sizes of bars in spiral galaxies? [PDF]

Monthly Notices of the Royal Astronomical Society, 2019
ABSTRACT I use volume- and mass-limited subsamples and recently published data from the Spitzer Survey of Stellar Structure in Galaxies (S4G) to investigate how the size of bars depends on galaxy properties. The known correlation between bar semimajor axis a and galaxy stellar mass (or luminosity) is actually bimodal: for $\log \, (M_ ...

A Chromosome Inversion Creates a Supergene for Sex and Colour in Lake Malawi Cichlids

Molecular Ecology, EarlyView.
ABSTRACT Cichlid fishes have the highest rates of evolutionary turnover of sex chromosomes among vertebrates. Many large structural polymorphisms in the radiation of cichlids in Lake Malawi are associated with sex chromosomes and may also carry adaptive variation.

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
