Ion Acoustic Travelling Waves
G. M. Webb, R. H. Burrows, X. Ao +1
Models for travelling waves in multi-fluid plasmas give essential insight into fully nonlinear wave structures in plasmas, not readily available from either numerical simulations o…
Constraints on supermassive black hole spins from observations of active galaxy jets
E. Kun, P. J. Wiita, L. Á. Gergely +3
We discuss the origin of the low-energy cutoff, or LEC, seen in the radio spectra of many extragalactic jets and relate this to the spin of the supermassive black holes that presum…
Fermi-LAT Observations of the Gamma-ray Burst GRB 130427A
LAT collaboration, GBM collaboration
The observations of the exceptionally bright gamma-ray burst (GRB) 130427A by the Large Area Telescope aboard the Fermi Gamma-ray Space Telescope provide constraints on the nature…
Multi-Symplectic Magnetohydrodynamics
G. M. Webb, J. F. McKenzie, G. P. Zank
A multi-symplectic formulation of ideal magnetohydrodynamics (MHD) is developed based on a Clebsch variable variational principle in which the Lagrangian consists of the kinetic mi…

We present systematic spectral analyses of GRBs detected with the Burst and Transient Source Experiment (BATSE) onboard the Compton Gamma-Ray Observatory (CGRO) during its entire n…
An Environment-dependent Semi-Empirical Tight Binding Model Suitable for Electron Transport in Bulk Metals, Metal Alloys, Metallic Interfaces and Metallic Nanostructures I - Model and Validation
Ganesh Hegde, Michael Povolotskyi, Tillmann Kubis +2

The First Pulse of the Extremely Bright GRB 130427A: A Test Lab for Synchrotron Shocks
R. Preece, J. Michael Burgess, A. von Kienlin +156
Gamma-ray burst (GRB) 130427A is one of the most energetic GRBs ever observed. The initial pulse up to 2.5 s is possibly the brightest well-isolated pulse observed to date. A fine…
The Bright Optical flash and Afterglow from the Gamma-Ray Burst GRB 130427A
W. T. Vestrand, J. Wren, A. Panaitescu +9
The optical light that is generated simultaneously with the x-rays and gamma-rays during a gamma-ray burst (GRB) provides clues about the nature of the explosions that occur as mas…
Measurement of the dispersion of radiation from a steady cosmological source
Richard Lieu, Lingze Duan, T. W. B. Kibble
The `missing baryons' of the near universe are believed to be principally in a partially ionized state. Although passing electromagnetic waves are dispersed by the plasma, the effe…
Predicting the Sun's Polar Magnetic Fields with a Surface Flux Transport Model
Lisa Upton, David H. Hathaway
The Sun's polar magnetic fields are directly related to solar cycle variability. The strength of the polar fields at the start (minimum) of a cycle determine the subsequent amplitu…
Super-Eddington Accretion in the Ultraluminous X-ray Source NGC1313 X-2: An Ephemeral Feast
Shan-Shan Weng, Shuang-Nan Zhang, Hai-Hui Zhao
We investigate the X-ray spectrum, variability and the surrounding ionized bubble of NGC1313 X-2 to explore the physics of super-Eddington accretion. Beyond the Eddington luminosit…
Formation and Eruption of an Active Region Sigmoid: I. Study by Nonlinear Force-Free Field Modeling
Chaowei Jiang, S. T. Wu, Xueshang Feng +1
We present a magnetic analysis of the formation and eruption of an active region (AR) sigmoid in AR 11283 from 2011 September 4 to 6. To follow the quasi-static evolution of the co…
Gamma-Ray Burst Spectrum with Decaying Magnetic Field
X. H. Zhao, Z. Li, X. W. Liu +3
In the internal shock model for gamma-ray bursts (GRBs), the synchrotron spectrum from the fast cooling electrons in a homogeneous downstream magnetic field (MF) is too soft to pro…
The origin of cold gas in giant elliptical galaxies and its role in fueling radio-mode AGN feedback
N. Werner, J. B. R. Oonk, M. Sun +12
We present a multi-wavelength study of the interstellar medium in eight nearby, X-ray and optically bright, giant elliptical galaxies. Using Herschel PACS, we map the cold gas in t…
How Long does a Burst Burst?
Bin-Bin Zhang, Bing Zhang, Kohta Murase +2
Several gamma-ray bursts (GRBs) last much longer (~hours) in gamma-rays than typical long GRBs (~ minutes), and recently it was proposed that these "ultra-long GRBs" may form a dis…
Pitch-angle scattering in magnetostatic turbulence. I. Test-particle simulations and the validity of analytical results
R. C. Tautz, A. Dosch, F. Effenberger +2
Context. Spacecraft observations have motivated the need for a refined description of the phase-space distribution function. Of particular importance is the pitch-angle diffusion c…
