The Complex Multiwavelength Morphology of the Peculiar Compact Galaxy Group IC 2431

The Astrophysical Journal
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

Galaxies
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.

Why z > 1 radio-loud galaxies are commonly located in protoclusters [PDF]

, 2014
Distant powerful radio-loud active galactic nuclei (RLAGN) tend to reside in dense environments and are commonly found in protoclusters at z > 1.3. We examine whether this occurs because RLAGN are hosted by massive galaxies, which preferentially reside ...

HST images and properties of the most distant radio galaxies [PDF]

, 1998
We present Hubble Space Telescope images of 11 high redshift radio galaxies (between $z=2.3$ and $z=3.6$). The galaxies were observed with the WFPC2 camera in a broad band filter (F606W or F707W, roughly equivalent to V or R-band), for 2 orbits each.

Radiogalaxies in the Sloan Digital Sky Survey: spectral index-environment correlations [PDF]

, 2010
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,

Models in Decision‐Making Under Risk and Uncertainty

Journal of Economic Surveys, EarlyView.
ABSTRACT This paper systematically compares dominant frameworks for modeling decision‐making under risk and uncertainty, evaluating their theoretical trade‐offs and practical relevance for economic research. We establish key criteria for model selection—including predictive accuracy, descriptive realism, computational tractability, and ecological ...

A Panchromatic View of Relativistic Jets in Narrow-Line Seyfert 1 Galaxies

Galaxies, 2016
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 ...

Numerical modelling of the lobes of radio galaxies in cluster environments [PDF]

, 2013
We have carried out two-dimensional, axisymmetric, hydrodynamic numerical modelling of the evolution of radio galaxy lobes. The emphasis of our work is on including realistic hotgas environments in the simulations and on establishing what properties of ...

The Effect of Clear Aligners on Awareness of Tooth Clenching

Journal of Oral Rehabilitation, EarlyView.
Clear aligners do not influence perceived or EMG‐assessed clenching, while somatization emerges as a key mediator in the relationship between clenching and aligner wear. ABSTRACT Introduction Clear aligners (CAs) are an increasingly popular treatment option in modern dentistry, yet surprisingly little is known about their potential unwanted side ...

UNIFIED SCHEMES FOR RADIO-LOUD ACTIVE GALACTIC NUCLEI [PDF]

, 1995
The appearance of active galactic nuclei (AGN) depends so strongly on orientation that our current classification schemes are dominated by random pointing directions instead of more interesting physical properties.
