Discovery of a Barred-spiral Galaxy at zspec = 3.16. I. Bar Identification and Properties
The Astrophysical JournalThe formation of stellar bars is an important milestone in the secular evolution of spiral galaxies, which typically indicates the presence of a massive rotationally supported disk.

Quantifying the Unwinding Due to Ram Pressure Stripping in Simulated Galaxies
GalaxiesGalaxies moving through the gas of the intracluster medium (ICM) experience ram pressure stripping, which can leave behind a gas tail. When a disk galaxy receives the wind edge-on, however, the characteristic signature is not a typical jellyfish tail ...

Here Be SDRAGNs—Spiral Galaxies Hosting Large Double Radio Sources
The Astronomical JournalWe present a sample of large double radio sources hosted by spiral galaxies (spiral double radio active galactic nuclei, SDRAGNs). Candidates were initially selected through the Radio Galaxy Zoo project and subsequently refined using Sloan Digital Sky ...

A Review of Failure Modes and Safety Strategies of Lithium‐Ion Batteries from Materials to Systems
Advanced Science, Volume 13, Issue 42, 28 July 2026.A cascade‐aware framework is presented for lithium‐ion battery safety, linking thermal runaway initiation, acceleration, runaway reaction, and propagation with material‐, cell/pack‐, and system‐level interventions. By integrating failure mechanisms, quantitative safety indicators, and staged interception strategies, this review highlights how safer ...

The Theory of Spiral Structure of Galaxies [PDF]
Symposium - International Astronomical Union, 1970 A Landau-type instability mechanism for generating spiral waves is suggested.Two populations of stars, Populations I and II, are considered, the second one with mean rotational velocity zero. Then a dispersion relation is derived which is reduced to the Lin-Shu dispersion relation in the case of vanishing Population II. The amplification of the wave is

Star Formation in the Lopsided Galaxy Arp 291
The Astrophysical JournalWe have investigated the star formation process taking place in the lopsided galaxy Arp 291, based on narrowband images in the H α , [N ii ] λ 6583, and [O iii ] λ 5007 emission lines, obtained using the modern tunable photometer MaNGaL at the Caucasus ...

Supramolecular Aggregates of Amino Acid‐Functionalized 1,8‐Naphthalimides for Chiral Recognition
Chemistry–Methods, Volume 6, Issue 7, July 2026.We synthesized three self‐assembling, amino acid‐functionalized 1,8‐naphthalimides. We studied their aggregation in solution and demonstrated their chiral recognition ability by fluorescence and resonance light scattering measurements. Notably, these fluorescent probes maintain their chiral recognition ability when incorporated in solid supports like ...

Disk Galaxy Models Driven by Stochastic Self-Propagating Star Formation
Open Astronomy, 2010 We present a model of chemical and spectrophotometric evolution of disk galaxies based on a stochastic self-propagating star formation scenario. The model incorporates galaxy formation through the process of accretion, chemical and photometric evolution ...
