The Supercritical Pile GRB Model : The Prompt to Afterglow Evolution
The " Supercritical Pile " is a very economical GRB model that provides for the efficient conversion of the energy stored in the protons of a Relativistic Blast Wave (RBW) into radiation and at the same time produces-in the prompt GRB phase, even in the absence of any particle acceleration-a spectral peak at energy ∼ 1 MeV. We extend this model to include the evolution of the RBW Lorentz factor...
متن کاملSwift observations of the prompt X - ray emission and afterglow from GRB 050126 & GRB 050219 A
We report on the temporal and spectral characteristics of the early X-ray emission from the Gamma Ray Bursts GRB050126 and GRB050219A as observed by Swift. The X-ray light-curves of these 2 bursts both show remarkably steep early decays (F(t) ∝ t−3), breaking to flatter slopes on timescales of a few hundred seconds. For GRB050126 the burst shows no evidence of spectral evolution in the 20-150 k...
متن کاملPrompt and afterglow emission from the X - ray rich GRB 981226 observed with
We discuss observations of the prompt X– and γ–ray emission and X–ray afterglow from GRB981226. This event has the weakest gamma-ray peak flux detected with the BeppoSAX Gamma-Ray Burst Monitor. It shows an isolated X-ray precursor and the highest X-ray to gamma-ray fluence ratio measured thus far with the BeppoSAX Wide Field Cameras. The event was followed up with the BeppoSAX Narrow Field Ins...
متن کاملPrompt GRB emission from gradual energy dissipation
I calculate the emission expected from a Poynting-flux-dominated gamma-ray burst (GRB) flow in which energy is dissipated gradually by magnetic reconnection. In this picture, the energy of the radiating particles is determined by heating and cooling balance (slow heating model). Detailed radiative transfer calculations show that, at Thomson optical depths of order of unity, the dominant radiati...
متن کاملPanchromatic study of GRB 060124: from precursor to afterglow
We present observations of GRB 060124, the first event for which both the prompt and the afterglow emission could be observed simultaneously and in their entirety by the three Swift instruments. Indeed, Swift-BAT triggered on a precursor ∼ 570 s before the main burst peak, and this allowed Swift to repoint the narrow field instruments to the burst position ∼ 350 s before the main burst occurred...
