Swift and Fermi observations of X-ray flares: the case of Late Internal Shock
E. Troja, L. Piro, V. Vasileiou +5
Simultaneous Swift and Fermi observations of gamma-ray bursts (GRBs) offer a unique broadband view of their afterglow emission, spanning more than ten decades in energy. We present…

We present two different search methods for electromagnetic counterparts to gravitational-wave (GW) events from ground-based detectors using archival NASA high-energy data from the…
Pitch-angle scattering of energetic particles with adiabatic focusing
R. C. Tautz, A. Shalchi, A. Dosch
Understanding turbulent transport of charged particles in magnetized plasmas often requires a model for the description of random variations in the particle's pitch angle. The Fokk…
A Study of the Early-stage Evolution of Relativistic Electron-Ion Shock using 3D PIC Simulations
E. J. Choi, K. Min, K. -I. Nishikawa +1
We report the results of a 3D particle-in-cell (PIC) simulation carried out to study the early-stage evolution of the shock formed when an unmagnetized relativistic jet interacts w…
GROND coverage of the main peak of Gamma-Ray Burst 130925A
J. Greiner, H. -F. Yu, T. Krühler +23
Prompt or early optical emission in gamma-ray bursts is notoriously difficult to measure, and observations of the dozen cases show a large variety of properties. Yet, such early em…
The Magneto Hydro Dynamical Model of KHz Quasi Periodic Oscillations in Neutron Star Low Mass X-ray Binaries (II)
Chang-Sheng Shi, Shuang-Nan Zhang, Xiang-Dong Li
We study the kilohertz quasi-periodic oscillations (kHz QPOs) in neutron star low mass X-ray binaries (LMXBs) with a new magnetohydrodynamics (MHD) model, in which the compressed m…
Jet Properties of GeV-Selected Radio-Loud Narrow-Line Seyfert 1 Galaxies and Possible Connection to Their Disk and Corona
Xiao-Na Sun, Jin Zhang, Da-Bin Lin +3
The observed spectral energy distributions of five GeV-selected narrow-line Seyfert 1 (NLS1) galaxies are fitted with a model including the radiation ingredients from the relativis…
Gamma Ray Bursts Are Observed Off-Axis

We have investigated magnetic field generation in velocity shears via the kinetic Kelvin-Helmholtz instability (kKHI) using a relativistic plasma jet core and stationary plasma she…
An Analysis of Chandra Deep Follow-up GRBs: Implications for Off-Axis Jets
Bin-Bin Zhang, Hendrik van Eerten, David N. Burrows +5
We present a sample of 27 GRBs with detailed Swift light curves supplemented by late time Chandra observations. To answer the missing jet-break problem in general, we develop a num…
