Estimating Long GRB Jet Opening Angles and Rest-Frame Energetics
Adam Goldstein, Valerie Connaughton, Michael S. Briggs +1
We present a method to estimate the jet opening angles of long duration Gamma-Ray Bursts (GRBs) using the prompt gamma-ray energetics and an inversion of the Ghirlanda relation, wh…
Do the Fermi Gamma-Ray Burst Monitor and Swift Burst Alert Telescope see the Same Short Gamma-Ray Bursts?
Eric Burns, Valerie Connaughton, Bin-Bin Zhang +5
Compact binary system mergers are expected to generate gravitational radiation detectable by ground-based interferometers. A subset of these, the merger of a neutron star with anot…
NuSTAR discovery of a cyclotron absorption line in the transient X-ray pulsar 2S 1553-542
Sergey S. Tsygankov, Alexander A. Lutovinov, Roman A. Krivonos +4
We report results of a spectral and timing analysis of the poorly studied transient X-ray pulsar 2S 1553-542 using data collected with the NuSTAR and Chandra observatories and the…
Investigation of Primordial Black Hole Bursts using Interplanetary Network Gamma-ray Bursts
T. N. Ukwatta, K. Hurley, J. H MacGibbon +22
The detection of a gamma-ray burst (GRB) in the solar neighborhood would have very important implications for GRB phenomenology. The leading theories for cosmological GRBs would no…
Multi-wavelength light curve evolution of Swift J1357.2-0933 during its 2011 outburst
Shan-Shan Weng, Shuang-Nan Zhang
Swift J1357.2-0933 underwent an episodic accretion in 2011 and provided very regular temporal and spectral evolution, making it an ideal source for exploring the nature of very fai…
Evolution of Global Relativistic Jets: Collimations and Expansion with kKHI and the Weibel Instability
K. I Nishikawa, J. T. Frederiksen, A. Nordlund +10
One of the key open questions in the study of relativistic jets is their interaction with the environment. Here, we study the initial evolution of both electron-proton and electron…
Efficient Production of High-energy Nonthermal Particles during Magnetic Reconnection in a Magnetically-dominated Ion-Electron Plasma
Fan Guo, Xiaocan Li, Hui Li +6
Magnetic reconnection is a leading mechanism for dissipating magnetic energy and accelerating nonthermal particles in Poynting-flux dominated flows. In this letter, we investigate…
The optical identifcation of events with poorly defined locations: The case of the Fermi GBM GRB140801A
V. M. Lipunov, J. Gorosabel, M. V. Pruzhinskaya +50
We report the early discovery of the optical afterglow of gamma-ray burst (GRB) 140801A in the 137 deg 3- error-box of the Fermi Gamma-ray Burst Monitor (GBM). MASTER is the…
The Transient Accereting X-Ray Pulsar XTE J1946+274: Stability of the X-Ray Properties at Low Flux and Updated Orbital Solution
Diana M. Marcu-Cheatham, Katja Pottschmidt, Matthias Kühnel +19
We present a timing and spectral analysis of the X-ray pulsar XTE J1946+274 observed with Suzaku during an outburst decline in 2010 October and compare with previous results. XTE J…
Collisionless Weibel shocks and electron acceleration in gamma-ray bursts
Kazem Ardaneh, Dongsheng Cai, Ken-Ichi Nishikawa +1
A study of collisionless external shocks in gamma-ray bursts is presented. The shock structure, electromagnetic fields, and process of electron acceleration are assessed by perform…
The sharpness of gamma-ray burst prompt emission spectra
Hoi-Fung Yu, Hendrik J. van Eerten, Jochen Greiner +5
We aim to obtain a measure of the curvature of time-resolved spectra that can be compared directly to theory. This tests the ability of models such as synchrotron emission to expla…
Recollimation Shocks in Magnetized Relativistic Jets
Yosuke Mizuno, Jose L. Gomez, Ken-Ichi Nishikawa +3
We have performed two-dimensional special-relativistic magnetohydrodynamic simulations of non-equilibrium over-pressured relativistic jets in cylindrical geometry. Multiple station…
Modeling the evolution and distribution of the frequency's second derivative and the braking index of pulsar spin
Yi Xie, Shuang-Nan Zhang, Jin-Yuan Liao
We model the evolution of the spin frequency's second derivative and the braking index of radio pulsars with simulations within the phenomenological model of their sur…
Synchrotron Origin of the Typical GRB Band Function - A Case Study of GRB 130606B
Bin-Bin Zhang, Z. Lucas Uhm, Valerie Connaughton +2
We perform a time-resolved spectral analysis of GRB 130606B within the framework of a fast-cooling synchrotron radiation model with magnetic field strength in the emission region d…
Pulse properties of terrestrial gamma-ray flashes detected by the Fermi Gamma-Ray Burst Monitor
Suzanne Foley, Gerard Fitzpatrick, Michael S. Briggs +17
The Gamma-ray Burst Monitor (GBM) on board the Fermi Gamma-ray Space Telescope has triggered on over 300 terrestrial gamma-ray flashes (TGFs) since its launch in June 2008. With 14…
Compton scattering in terrestrial gamma-ray flashes detected with the Fermi gamma-ray burst monitor
Gerard Fitzpatrick, Eric Cramer, Sheila McBreen +11
Terrestrial gamma-ray flashes (TGFs) are short intense flashes of gamma rays associated with lightning activity in thunderstorms. Using Monte Carlo simulations of the relativistic…
