High‐Contrast Colorless‐to‐Colored Thermochromic Materials

open access: yesSmall, EarlyView.
We developed new three‐component thermochromic systems showing reversible colorless‐to‐colored transition. Our general empirical rule applies to diverse fatty acid phase change materials and leuco dyes, enabling easily tunable transition temperature and activated colors (blue, cyan, green, pink, grey). Solid particles of these materials were integrated

Weak-lensing Characterization of the Dark Matter in 29 Merging Clusters that Exhibit Radio Relics

open access: yesThe Astrophysical Journal Supplement Series
We present a multiwavelength analysis of 29 merging galaxy clusters that exhibit radio relics. For each merging system, we perform a weak-lensing analysis on Subaru optical imaging.

A Chandra study of X-ray sources in the field of the z=2.16 radio galaxy MRC 1138-262 [PDF]

open access: yes, 2002
We present results from a Chandra X-ray Observatory study of the field X-ray source population in the vicinity of the radio galaxy MRC 1138-262. Many serendipitous X-ray sources are detected in an area of 8'x8' around the radio source and 90% are ...

Saving Bambi from the mower? Using a drone with thermal camera to evaluate a low‐tech scaring technique to reduce roe deer fawn mortality during grass harvest

open access: yesWildlife Biology, EarlyView.
Roe deer is a species that hides their neonates as an anti‐predator strategy. This may prove efficient against mammalian predators, such as the red fox; however, it might be an ecological trap as large numbers of fawns are killed by tractors with harvesters each year during grass harvest.

Weak-lensing Analysis of the Complex Cluster Merger A746 with Subaru/Hyper Suprime-Cam

open access: yesThe Astrophysical Journal
The galaxy cluster A746 ( z = 0.214), featuring a double radio relic system, two isolated radio relics, a possible radio halo, disturbed V-shaped X-ray emission, and intricate galaxy distributions, is a unique and complex merging system.

High-energy Neutrino Constraints on Cosmic-Ray Reacceleration in Radio Halos of Massive Galaxy Clusters

open access: yesThe Astrophysical Journal, 2023
A fraction of merging galaxy clusters host diffuse radio emission in their central region, termed a giant radio halo (GRH). The most promising mechanism of GRHs is the reacceleration of nonthermal electrons and positrons by merger-induced turbulence ...

Radio Galaxy Classification: #Tags, Not Boxes

open access: yesGalaxies, 2021
After six decades of studying radio galaxies, we are now delightfully overwhelmed by their exponentially expanding numbers and the complexity of their structures.

High Frequency Cluster Radio Galaxies: Luminosity Functions and Implications for SZE Selected Cluster Samples

open access: yes, 2016
We study the overdensity of point sources in the direction of X-ray-selected galaxy clusters from the Meta-Catalog of X-ray detected Clusters of galaxies (MCXC; $\langle z \rangle = 0.14$) at South Pole Telescope (SPT) and Sydney University Molonglo Sky ...

Radiation‐Induced Degradation in Polymeric Materials: Alterations in Physical–Chemical Properties and Their Effects on Electrical Performance of Insulation Systems

open access: yesHigh Voltage, EarlyView.
ABSTRACT This paper investigates the effects of radiation on polymeric materials used as insulation systems in electrical equipment such as cables for nuclear and particle accelerator applications. After a detailed description of the physics of radiation‐induced damage in the polymeric matrix, a comprehensive analysis of the physical–chemical and ...
