Radio Galaxy Zoo: The Distortion of Radio Galaxies by Galaxy Clusters

, 2019
We study the impact of cluster environment on the morphology of a sample of 4304 extended radio galaxies from Radio Galaxy Zoo. A total of 87% of the sample lies within a projected 15 Mpc of an optically identified cluster.

Thermochromic Gires‐Tournois Resonators with Tellurium for Battery Thermal Runaway Warning

Advanced Materials, Volume 37, Issue 40, October 9, 2025.
A thermochromic Gires‐Tournois (GT) resonator with a thin tellurium layer enables rapid, reversible, and untethered detection of battery surface temperature <80 °C. Exploiting tellurium's refractive index change driven by a thermally induced phase transition between solid and quasi‐liquid states, the GT resonator visualizes heat propagation, providing ...

The Cosmic Ultraviolet Baryon Survey (CUBS). VIII. Group Environment of the Most Luminous Quasars at z ≈ 1

The Astrophysical Journal
We investigate the group-scale environment of 15 luminous quasars (luminosity L _3000 > 10 ^46 erg s ^−1 ) from the Cosmic Ultraviolet Baryon Survey (CUBS) at redshift z ≈ 1.

Vision Transformer‐Enhanced Multi‐Descriptor Approach for Robust Age‐Invariant Face Recognition

Applied AI Letters, Volume 6, Issue 3, October 2025.
ABSTRACT This study presents a robust age‐invariant face recognition framework, addressing challenges posed by age‐related facial variations. Evaluated on the FGNet and Morph II datasets, the system integrates Viola‐Jones for face detection, SIFT and LBP for feature extraction, and Vision Transformers (ViTs) for global feature representation.

Clustering and light profiles of galaxies in the environment of 20 Ultra Steep Spectrum Radio sources

, 2003
We have analyzed galaxy properties in the neighborhood of 20 Ultra-Steep Spectrum Radio sources (USS) taken from the WISH catalog of De Breuck et al. (2002). Galaxies in these USS fields were identified in deep observations that were carried out in the K'

From Fabrication to Failure—Aqueous Processing, Electrolyte Tuning, and Degradation Mechanism Elucidation in Poly(3‐Vinyl‐N‐Methylphenoxazine) Positive Electrodes

ChemSusChem, Volume 18, Issue 19, October 1, 2025.
Organic electrode materials are considered the next generation of battery electrode materials due to their environmental friendliness, low toxicity and competitive specific capacities. Herein, we report on a systematic study of processing of the redox polymer poly(3‐vinyl‐N‐methylphenoxazine) (PVMPO) using water processable binders, achieving ...

On the connection between giant radio halos and cluster mergers

, 2010
The frequently observed association between giant radio halos and merging galaxy clusters has driven present theoretical models of non-thermal emission from galaxy clusters, which are based on the idea that the energy dissipated during cluster-cluster ...

Circular Mystery: Exploring Diffuse Emission Surrounding a Radio Galaxy with uGMRT and VLA Multiwavelength Observations

The Astrophysical Journal
We report the discovery of J1218+1813, a circular diffuse radio source detected in the Very Large Array (VLA) FIRST survey at 1400 MHz. The source has an angular diameter of approximately one arcminute, corresponding to a physical size of ∼180 kpc, and ...

Loss of PI3Kδ Activity Drives Autoimmune Colitis by Impairing Extrathymic Treg Differentiation

European Journal of Immunology, Volume 55, Issue 10, October 2025.
Mice with inactivated PI3Kδ develop colitis, reminiscent of immune‐related adverse effects observed in human patients treated with PI3Kδ inhibitors. We demonstrate that loss of PI3Kδ activity abrogates the Helios− peripherally induced Treg (pTreg) population in the mouse colon, resulting in inflammation and tissue damage that Helios+ thymic Tregs fail ...
