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).

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.

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 ...

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.

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 ...

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.

Hunting for Paradoxes: A Research Strategy for Cognitive Science
Topics in Cognitive Science, EarlyView.Abstract How should we identify interesting topics in cognitive science? This paper suggests that one useful research strategy is to hunt for, and attempt to resolve, paradoxes: that is, apparent or real contradictions in our understanding of the mind and of thought.

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

Catching butterflies in the sky: Extended catalog of winged or X-shaped radio sources from the latest FIRST data release [PDF]
, 2019 We present a catalog of 290 "winged" or X-shaped radio galaxies (XRGs) extracted from the latest (2014 December 17) data release of the "Very Large Array Faint Images of the Radio Sky at Twenty centimeter." We have combined these radio images with their ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...
