Cosmological gamma-ray bursts and the highest energy cosmic rays.
نویسنده
چکیده
We discuss a scenario in which the highest energy cosmic rays (CR's) and cosmological-ray bursts (GRB's) have a common origin. This scenario is consistent with the observed CR ux above 10 20 eV, provided that each burst produces similar energies in-rays and in CR's above 10 20 eV. Protons may be accelerated by Fermi's mechanism to energies 10 20 eV in a dissipative, ultra-relativistic wind, with luminosity and Lorentz factor high enough to produce a GRB. For a homogeneous GRB distribution, this scenario predicts an isotropic, time-independent CR ux.

Are Extragalactic Gamma Ray Bursts The Source Of The Highest Energy Cosmic Rays?
Recent observations with the large air shower arrays of ultra high energy cosmic rays (UHECR) and recent measurements/estimates of the redshifts of gamma ray bursts (GRBs) seem to rule out extragalactic GRBs as the source of the cosmic rays that are observed near Earth, including those with the highest energies.

متن کاملOn the Spectrum of Ultrahigh Energy Cosmic Rays and the Gamma Ray Burst Origin Hypothesis
It has been suggested that cosmological γ-ray bursts (GRBs) can produce the observed flux of cosmic rays at the highest energies. However, recent studies of γ-ray bursts indicate that their redshift distribution likely follows the average star formation rate of the universe and that GRBs were more numerous at high redshifts. As a consequence, we show that photomeson production energy losses suf...
متن کاملCosmic Rays and Gamma Ray Bursts From Microblazars
Highly relativistic jets from merger and accretion induced collapse of compact stellar objects, which may produce the cosmological gamma ray bursts (GRBs), are also very eficient and powerful cosmic ray accelerators. The expected luminosity, energy spectrum and chemical composition of cosmic rays from Galactic GRBs, most of which do not point in our direction, can explain the observed propertie...

In a letter with the above title, published some time ago in PRL, Waxman [1] made the interesting suggestion that cosmological gamma ray bursts (GRBs) are the source of the ultra high energy cosmic rays (UHECR). This has also been proposed independently by Milgrom and Usov [2] and by Vietri [3]. However, here I show that the recent data from AGASA [4], which does not show the suppression in the...
متن کاملCoronal Gamma Ray Bursts as the sources of Ultra High Energy Cosmic Rays?
I consider the possibility that Ultra High Energy Cosmic Rays are accelerated in Gamma Ray Bursts located in the Galactic corona, thus circumventing the problem raised by Greisen–Zatsepin–Kuz’min cutoff. The acceleration of UHECRs could occur in the pulsars which, in the coronal GRB model, produce them: the same parameters that permit fitting GRBs’ observations in the model of Podsiadlowski, Re...
