Gamma-Ray Burst Prompt Emission: Implications from Shock Acceleration Theory

The principal paradigm for gamma-ray bursts suggest that the prompt transient gamma-ray signal arises from multiple shocks internal to the relativistic expansion. This paper illustrates some properties of diffusive acceleration at relativistic shocks that pertain to GRB models, providing interpretation of the BATSE/EGRET data. Using a standard Monte Carlo simulation, computations of the spectra...

High Energy Emission from the Prompt Gamma-Ray Burst

We study the synchrotron and synchrotron self-Compton (SSC) emission from internal shocks that are responsible for the prompt γ-ray emission in GammaRay Bursts (GRBs), and consider the relation between these two components, taking into account the high energy cutoff due to pair production and Thomson scattering. We find that in order for the peak energy of the synchrotron to be Ep ∼ 300 keV wit...

Tail Emission of Prompt Gamma-Ray Burst Jets

Tail emission of the prompt gamma-ray burst (GRB) is discussed using a multiple emitting sub-shell (inhomogeneous jet, sub-jets or mini-jets) model, where the whole GRB jet consists of many emitting sub-shells. One may expect that such a jet with angular inhomogeneity should produce spiky tail emission. However, we found that the tail is not spiky but is decaying roughly monotonically. The glob...

“late Prompt” Emission in Gamma Ray Bursts?

The flat decay phase in the first 10–10 seconds of the X–ray light curve of Gamma Ray Bursts (GRBs) has not yet found a convincing explanation. The fact that the optical and X–ray lightcurves are often different, with breaks at different times, makes contrived any explanation based on the same origin for both the X–ray and optical fluxes. We here assume that the central engine can be active for...

Prompt Neutrino Emission from Gamma-Ray Bursts

Recent observations show that some or possibly all long-duration gamma-ray bursts (GRBs) arise from the core collapse of massive stars. In this case, the GRB environments are believed to be preburst stellar winds. We here study prompt neutrino emission from reverse shocks as a result of the interaction of relativistic fireballs with their surrounding wind matter. We find that for reasonable par...
