Galaxy zoo builder:morphological dependence of spiral galaxy pitch angle [PDF]

, 2021
Spiral structure is ubiquitous in the Universe, and the pitch angle of arms in spiral galaxies provide an important observable in efforts to discriminate between different mechanisms of spiral arm formation and evolution.

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling

Computer Graphics Forum, EarlyView.
Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.

Dynamics of stars around spiral arms in an N-body/SPH simulated barred spiral galaxy [PDF]

We run N-body smoothed particle hydrodynamics (SPH) simulations of a Milky Way-sized galaxy. The code takes into account hydrodynamics, self-gravity, star formation, supernova and stellar wind feedback, radiative cooling and metal enrichment.

Morphology and Kinematics of the Gas in M51: How Interaction with NGC 5195 Has Molded the Structure of Its Arms

The Astrophysical Journal
The Whirlpool Galaxy is a well-studied grand design galaxy with two major spiral arms, and a large satellite NGC 5195. The arms both show long uniform sections with perturbations (“kinks” or sharp turns) in specific regions.

Bronchoscopy Robot with Enhanced Flexibility and Stability via Multi‐Segment Variable Stiffness Catheter

Advanced Intelligent Systems, Volume 8, Issue 9, September 2026.
This work presents a magnetic bronchoscopy robot with a novel multi‐segment variable stiffness catheter. This catheter can not only move flexibly in the narrow bronchi but also harden according to the need to provide support. Combined with remote wireless magnetic field drive, it provides a more precise and effective solution for biopsy of deep lung ...

PANORAMIC: Discovery of an ultra-massive grand-design spiral galaxy at [PDF]

We report the discovery of an ultra-massive grand-design red spiral galaxy, named Zhúlóng (Torch Dragon), at $ z_{\mathrm{phot}} = 5.2^{+0.3}_{-0.2} $ in the JWST PANORAMIC survey; it is the most distant bulge+disk galaxy candidate with spiral arms known

Cosmic Ray Anisotropy Generated by the June 22nd 2015 Interplanetary Events

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract On 22 June 2015, the near Earth interplanetary space was perturbed by a series of high‐speed streamers and interplanetary coronal mass ejections associated with an active region and two low‐latitude coronal holes. The interaction of these disturbances gave rise to the complex solar wind structure observed at 1 au.

Hierarchical star formation across the grand-design spiral NGC 1566 [PDF]

, 2017
We investigate how star formation is spatially organized in the grand-design spiral NGC 1566 from deep $\textit{Hubble Space Telescope}$ photometry with the Legacy ExtraGalactic UV Survey.

Grand Design vs. Multi-Armed Spiral Galaxies: Dependence on Galaxy Structure [PDF]

We developed an algorithm to use Galaxy Zoo 3D spiral arm masks produced by citizen scientist volunteers to semi-automatically classify spiral galaxies as either multi-armed or grand design spirals.

Genomic Insights Into the Multimetal Resilience and Biofilm‐Templated Nanorod Biosynthesis of Stenotrophomonas bentonitica BII‐R7: Bioremediation and Green Nanotechnology Implications

Microbial Biotechnology, Volume 19, Issue 9, September 2026.
Biofilm extracellular polymeric substances (EPS) in Stenotrophomonas bentonitica BII‐R7 direct the formation of crystalline trigonal selenium nanorods. Comparative genomics identifies a unique genetic toolkit underpinning EPS composition and metal resilience, positioning this strain as a platform for bioremediation and green nanomaterial synthesis ...
