Stellar Bars in Isolated Gas-rich Spiral Galaxies Do Not Slow Down
Elongated bar-like features are ubiquitous in galaxies, occurring at the centers of approximately two-thirds of spiral disks in the nearby Universe. Due to gravitational interactions between the bar and the other components of galaxies, it is expected ...

The Milky Way’s Circular Velocity Curve Measured Using Element Abundance Gradients
Spectroscopic surveys now supply precise stellar label measurements such as element abundances for large samples of stars throughout the Milky Way. These element abundances are known to correlate with orbital actions or other dynamical invariants.

Grand challenges in Milky Way and galaxies [PDF]
Extragalactic astronomy is a relatively young science. Its birth may be set at the time of the “greatdebate”betweenHarlowShapleyandHeberCurtisontheextragalacticnatureofthenebulae(whichculminated with a meeting of the two protagonists in April 1920) or, with a more conservativestance,afewyearslateratthetimeofEdwinHubble ...

Schematic depicting a gut‐brain pathway that exacerbates CST injury after ICH. Gut Microbiota Dysbiosis‐Mediated Gut NLRP3 Inflammasome Activation Exacerbates Corticospinal Tract Injury After Intracerebral Hemorrhage. Abstract Intracerebral hemorrhage (ICH) causes severe neurological deficits largely attributable to corticospinal tract (CST) injury ...

A study of radio continuum emission of the Milky Way Galaxy [PDF]
The synchrotron emissivity distribution of the Milky Way Galaxy has been modelled from the 408 MHz allsky survey of Haslam et al.(1982) after separation of its thermal component with the help of IRAS 60 micron emission(Broadbent et al 1989).

The Age-dependent Vertical Actions of Young Stars in the Galaxy
Stars in the Galactic disk are born on cold, nearly circular orbits with small vertical excursions. After their birth, their orbits evolve, driven by small- or large-scale perturbations in the Galactic disk’s gravitational potential.

On Our Cosmic (In)significance
ABSTRACT This article discusses three interpretations of cosmic significance, all of which reveal something important about the notion of significance. Along the way, it proposes a unified view of significance by combining elements of each of the views.

The Milky Way Galaxy in which we live seems to be a normal spiral galaxy. But it can be hard to tell. Our perspective from within it precludes a "face-on" view like the picture above, which combines some real data with a lot of artistic liberty.

Gastroschisis‐Like Defect in a Crossbred Bovine Calf: Anatomical, Clinical and Surgical Perspectives
A gastroschisis‐like defect was observed in a one‐day‐old, crossbred bovine calf with evisceration of the pyloric abomasum and small intestine, likely resulting from prenatal rupture of an omphalocele. The calf presented with lethargy, hypothermia and metabolic derangements, along with elevated renal biomarkers.

On the spiral structure of the Milky Way Galaxy [PDF]
We consider the possible pattern of the overall spiral structure of the Galaxy, using data on the distribution of neutral (atomic), molecular, and ionized hydrogen, on the base of the hypothesis of the spiral structure being symmetric, i.e. the assumption that spiral arms are translated into each other for a rotation around the galactic center by 180° (
