VLA Polarimetry of Two Extended Radio Galaxies [PDF]
, 2000 Multi-wavelength VLA observations of two extended radio galaxies, 0235-197 and 1203+043 are presented. There is some evidence from earlier studies that these two sources exhibit low frequency (

High 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 ...

THE MAGNETIZED GALACTIC WIND AND SYNCHROTRON HALO OF THE STARBURST DWARF GALAXY IC 10 [PDF]
, 2016 We aim to explore whether strong magnetic fields can be effectively generated in low-mass dwarf galaxies and, if so, whether such fields can be affected by galactic outflows and spread out into the intergalactic medium (IGM).

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 ...

Cosmic rays and the magnetic field of the nearby starburst galaxy NGC 253 [PDF]
, 2008 Using radio polarimetry we study the connection between the transport of cosmic rays (CR's), the three-dimensional magnetic field structure, and features of other ISM phases in the halo of NGC 253.

Superwind-Driven Intense H_2 Emission in NGC 6240 [PDF]
, 2000 We have performed a long-slit K band spectroscopic observation of the luminous infrared galaxy NGC 6240. The peak position of the H_2 v=1-0 S(1) emission in the slit is located ~0.3" - 0.4" north of the southern nucleus. It is almost the midpoint between

The simplicity of physical laws
Noûs, EarlyView.Abstract Physical laws are strikingly simple, yet there is no a priori reason for them to be so. I propose that nomic realists—Humeans and non‐Humeans—should recognize simplicity as a fundamental epistemic guide for discovering and evaluating candidate physical laws.

Mapping the particle acceleration in the cool core of the galaxy cluster RX J1720.1+2638
, 2014 We present new deep, high-resolution radio images of the diffuse minihalo in the cool core of the galaxy cluster RX J1720.1+2638. The images have been obtained with the Giant Metrewave Radio Telescope at 317, 617 and 1280 MHz and with the Very Large ...

Lessons from the void: What Boltzmann brains teach
Analytic Philosophy, EarlyView.Abstract Some physical theories predict that almost all brains in the universe are Boltzmann brains, that is, short‐lived disembodied brains that are accidentally assembled as a result of thermodynamic or quantum fluctuations. Physicists and philosophers of physics widely regard this proliferation as unacceptable, and so take its prediction as a basis ...

Simulations of the merging galaxy cluster Abell 3376
, 2013 Observed galaxy clusters often exhibit X-ray morphologies suggestive of recent interaction with an infalling subcluster. Abell 3376 is a nearby (z=0.046) massive galaxy cluster whose bullet-shaped X-ray emission indicates that it may have undergone a ...
