Stellar Bars in Isolated Gas-rich Spiral Galaxies Do Not Slow Down
The Astrophysical Journal, 2023 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
The Astrophysical JournalSpectroscopic 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]
Frontiers in Astronomy and Space Sciences, 2015 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 ...

On Our Cosmic (In)significance
Ratio, EarlyView.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.

A study of radio continuum emission of the Milky Way Galaxy [PDF]
, 1996 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
The Astrophysical JournalStars 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.

Utopia Remembers: The Soviet Past in the Imagined Communist Future
The Russian Review, EarlyView.Abstract After a twenty‐five‐year hiatus, the reappearance of utopian literature in 1957 prompted Soviet literary watchdogs to corral the subgenre into an ideologically‐acceptable mold. A key requirement was for future generations to be depicted as reverently commemorating the past.

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.ABSTRACT The current trend of individualized food items (nutrient content and flavor) can be particularly valuable to support people's health and well‐being in isolated environments where access to fresh foods and diverse nutrition is difficult. At the same time, bioactive compounds and micronutrients can be employed to countermeasure any health ...
