On the origin of gamma-ray bursts.
Gamma-ray bursts are the most energetic explosions in the Universe, occurring at cosmological distances. The initial phase of the emission from these bursts is predominantly of gamma rays and stems from a highly relativistic outflow. The nature of this emission is still under debate. Here, I present the interpretation that the peak in the photon spectrum can be attributed to the black-body emis...
متن کاملOn the Origin of Gamma Ray Bursts
relativistic flows by star-light in dense stellar regions followed by emission of decay/recombination photons, which are beamed and boosted to γ ray energies in the observer frame, produce gamma ray bursts (GRBs). We show that this overlooked mechanism is able to convert efficiently baryonic kinetic energy release in merger or accretion induced collapse of neutron stars into cosmological GRBs a...
متن کاملGamma Ray Bursts and Cosmic Ray Origin
This paper presents the theoretical basis of the fireball/blast wave model, and some implications of recent results on GRB source models and cosmic-ray production from GRBs. BATSE observations of the prompt γ-ray luminous phase, and Beppo-SAX and long wavelength afterglow observations of GRBs are briefly summarized. Derivation of spectral and temporal indices of an adiabatic blast wave decelera...
متن کاملHeliospheric Origin of Gamma-ray Bursts
Systematic variations of average observational characteristics and correlation properties between different parameters of gamma-ray bursts (GRBs) with time from 1991 April to 1994 September are revealed. It is hard to explain the observed long-term variability by variations of experimental conditions. The variability of GRB properties with the time scale of months to years, together with the si...
