New Relativistic Particle-In-Cell Simulation Studies of Prompt and Early Afterglows from GRBs
K. -I. Nishikawa, J. Niemiec, H. Sol +8
Nonthermal radiation observed from astrophysical systems containing relativistic jets and shocks, e.g., gamma-ray bursts (GRBs), active galactic nuclei (AGNs), and microquasars com…
3-D GRMHD Simulations of Disk-Jet Coupling and Emission
K. -I. Nishikawa, Y. Mizuno, S. Fuerst +7
We have performed a fully three-dimensional general relativistic magnetohydrodynamic (GRMHD) simulation of jet formation from a thin accretion disk around a Schwarzschild black hol…
Particle Acceleration, Magnetic Field Generation, and Emission in Relativistic Shocks
K. -I. Nishikawa, P. Hardee, C. B. Hededal +4
Shock acceleration is an ubiquitous phenomenon in astrophysical plasmas. Plasma waves and their associated instabilities (e.g., Buneman, Weibel and other two-stream instabilities)…
A General Relativistic Magnetohydrodynamics Simulation of Jet Formation
K. -I. Nishikawa, G. Richardson, S. Koide +4
We have performed a fully three-dimensional general relativistic magnetohydrodynamic (GRMHD) simulation of jet formation from a thin accretion disk around a Schwarzschild black hol…
The decay of optical emission from the Gamma-Ray Burst GRB 970228
Titus J. Galama, Paul J. Groot, Jan van Paradijs +6
We present the R_c band light curve of the optical transient (OT) associated with GRB970228, based on re-evaluation of existing photometry. Data obtained until April 1997 suggested…
Gross Spectral Differences between Bright and Dim Gamma-Ray Bursts
R. J. Nemiroff, J. P. Norris, J. T. Bonnell +5
We find that dim gamma-ray bursts (GRBs) are softer than bright GRBs, as indicated on average by data from the Burst and Transient Source Experiment (BATSE) on board the Compton Ga…
