Shocking features in the merging galaxy cluster RXJ0334.2-0111 [PDF]

, 2016
© 2016 The Authors. We present a 66 ks Chandra X-ray observation of the galaxy cluster RXJ0334.2-0111. This deep observation revealed a unique bow shock system associated with a wide angle tail (WAT) radio galaxy and several intriguing substructures. The

X-shaped radio galaxy 3C 315

BOOK OF ABSTRACTS AND CONTRIBUTED PAPERS - International Meeting on Data for Atomic and Molecular Processes in Plasmas: Advances in Standards and Modelling
AbstractHere we want to investigate X-shaped radio galaxy 3C 315, which is a FRII source, but it lies very close to the FRI/FRII borderline. We used publicly available data from Leahy’s atlas of double radio-sources and NASA/IPAC Extragalactic Database (NED) in order to investigate its flux density, as well as the spectral index distribution.

FIRST "Winged" and X-shaped Radio Source Candidates: II. New Redshifts

, 2008
We report optical spectroscopic observations of X-shaped radio sources with the Hobby-Eberly Telescope and Multiple-Mirror Telescope, focused on the sample of candidates from the FIRST survey presented in Paper I (Cheung 2007).

The Abundance of X-Shaped Radio Sources I. VLA Survey of 52 Sources With Off-Axis Distortions [PDF]

, 2015
Cheung identified a sample of 100 candidate X-shaped radio galaxies using the NRAO FIRST survey; these are small-axial-ratio extended radio sources with off-axis emission.

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

The 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.

Playing Hard with Si: Challenges and Opportunities for New Materials in Radiation Therapy Dosimetry

Advanced Materials, EarlyView.
Silicon has been a cornerstone material of radiation therapy dosimetry for many decades, providing somewhat unchallenged performance. However, there are caveats to its use, requiring complex designs and, often, correction factors to provide accurate measurements.

NGC 2207/IC 2163: A Grazing Encounter with Large Scale Shocks [PDF]

, 2011
Radio continuum, Spitzer infrared, optical and XMM-Newton X-ray and UVM2 observations are used to study large-scale shock fronts, young star complexes, and the galactic nuclei in the interacting galaxies NGC 2207/IC 2163.

Simulating Radio Synchrotron Morphology, Spectra, and Polarization of Cosmic Ray Driven Galactic Winds

The Astrophysical Journal
The formation of galaxies is significantly influenced by galactic winds, possibly driven by cosmic rays due to their long cooling times and better coupling to plasma compared to radiation.

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

Advanced Materials, EarlyView.
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 ...

CGCG 292-057: A Near-Distance Merger Galaxy with Double–Double Radio Lobes and X-shape Structure [PDF]

Journal of Astrophysics and Astronomy, 2011
J1159+5820 is an extended radio galaxy with a quite unusual morphology, featuring two pairs of radio lobes. Such sources, called double–double radio galaxies, constitute a very rare class of extragalactic radio sources. Furthermore, the extended radio structure of this source shows an X-shape form. According to a much likely scenario, such a morphology
