X-rays from Radio-Galaxies: BeppoSAX Observations [PDF]
We briefly review BeppoSAX observations of X-ray bright radio-galaxies. Their X-ray spectra are quite varied, and perhaps surprisingly, any similarity between radio-loud AGN and Seyfert galaxies is the exception rather than the rule.

Synergies in Self‐Assembly—From Supramolecular Polymers to Defined Hierarchical Superstructures
Shaping supramolecular polymers built from molecular building blocks into superstructures with defined dimensions. Synergies within supramolecular architectures such as chirality or an additional second orthogonal driving force that does not interfere with the central supramolecular motif facilitate the confinement of the growth of these ...

The Complex Multiwavelength Morphology of the Peculiar Compact Galaxy Group IC 2431
We present new Chandra X-ray imaging spectroscopy of the compact galaxy group IC 2431, and compare with archival ultraviolet, optical, infrared, and radio images. IC 2431 is a starburst system containing three tidally distorted disk galaxies.

The Seeding of Cosmic Ray Electrons by Cluster Radio Galaxies: A Review
Radio galaxies in clusters of galaxies are a prominent reservoir of magnetic fields and of non-thermal particles, which become mixed with the intracluster medium.

A Panchromatic View of Relativistic Jets in Narrow-Line Seyfert 1 Galaxies
The discovery by the Large Area Telescope on board Fermi of variable γ-ray emission from radio-loud narrow-line Seyfert 1 (NLSy1) galaxies revealed the presence of a possible third class of Active Galactic Nuclei (AGN) with relativistic jets in addition ...

Radiogalaxies in the Sloan Digital Sky Survey: spectral index-environment correlations [PDF]
We analyze optical and radio properties of radiogalaxies detected in the Sloan Digital Sky Survey (SDSS). The sample of radio sources are selected from the catalogue of Kimball & Ivezi\'c (2008) with flux densities at 325, 1400 and 4850 MHz, using WENSS,

This study reports a parylene–plasma–porous (PPP) treatment that directionally transforms conventional porous membranes into dual‐gradient Janus structures. By aligning porosity and wettability gradients through asymmetric chemical‐vapor‐deposition (CVD) and localized O2 plasma treatment, the resulting membrane enables gravity‐independent self‐pumping ...

Radio Loud AGNs are Mergers [PDF]
We measure the merger fraction of Type 2 radio-loud and radio-quiet active galactic nuclei at z>1 using new samples. The objects have HST images taken with WFC3 in the IR channel.

Tools for Learning—Promoting Reflection for Student Teachers' Development of PCK
ABSTRACT This paper investigates how the coherent integration of three different tools for reflection during a science methods course can contribute to student teachers' planning and enactment of science teaching, that is, their development of pedagogical content knowledge (PCK).

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 ...
