IGR J14488-4008: an X-ray peculiar giant radio galaxy discovered by INTEGRAL [PDF]

, 2015
In this paper we report the discovery and detailed radio/X-ray analysis of a peculiar giant radio galaxy (GRG) detected by INTEGRAL, IGR J14488-4008. The source has been recently classified as a Seyfert 1.2 galaxy at redshift 0.123; the radio data denote

Effect of Background Magnetic Field on Ion Weibel Instability With High‐Intensity Short‐Pulse Lasers

Contributions to Plasma Physics, EarlyView.
ABSTRACT The effect of finite background magnetic field on magnetic field amplification by Weibel instability using high‐intensity short‐pulse lasers is investigated. We consider Weibel instability for counter‐streaming sub‐relativistic plasma flows generated by shooting pure carbon targets with short‐pulse lasers.

Isotropic AGN Heating with Small Radio Quiet Bubbles in the NGC 5044 Group

, 2009
(abridged) A Chandra observation of the X-ray bright group NGC 5044 shows that the X-ray emitting gas has been strongly perturbed by recent outbursts from the central AGN and also by motion of the central dominant galaxy relative to the group gas.

Betaine‐Conjugated ß‐Peptide Foldamers: Influence of Quaternary Charge on Self‐Organization and MorphologyFormation

ChemistryOpen, EarlyView.
N‐terminal betaine conjugation modifies β‐peptide helices, influencing folding and self‐organization. For [1S, 2S]‐ACPC, folding to an H12 helix was unaffected, while [1R, 2R]‐ACHC formed an H14 helix instead of H10. Alternating heterochiral oligomers made of enantiomeric pairs of trans‐ACPC showed enhanced solubility and E‐strand formation.

Radio Galaxy NGC 1265 unveils the Accretion Shock onto the Perseus Galaxy Cluster

, 2011
We present a consistent 3D model for the head-tail radio galaxy NGC 1265 that explains the complex radio morphology and spectrum by a past passage of the galaxy and radio bubble through a shock wave. Using analytical solutions to the full Riemann problem

Feeding Versus Feedback in AGNs from Near-Infrared IFU Observations: The Case of Mrk 766 [PDF]

, 2014
We have mapped the emission-line flux distributions and ratios as well as the gaseous kinematics of the inner 450 pc radius of the Seyfert 1 galaxy Mrk 766 using integral field near-IR J- and Kl-band spectra obtained with the Gemini nifs at a spatial ...

Synergies in Self‐Assembly—From Supramolecular Polymers to Defined Hierarchical Superstructures

Journal of Polymer Science, EarlyView.
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 ...

A radio study of the superwind galaxy NGC1482

, 2004
We present multifrequency radio continuum as well as HI observations of the superwind galaxy NGC1482, with both the GMRT and the VLA. This galaxy has a remarkable hourglass-shaped optical emission line outflow as well as bi-polar soft X-ray bubbles on ...
