Nuclear composition of gamma-ray burst fireballs
We study three processes that shape the nuclear composition of the fireballs in gamma-ray bursts (GRBs): (1) neutronization in the central engine, (2) nucleosynthesis in the fireball as it expands and cools, and (3) spallation of nuclei in subsequent internal shocks. The fireballs are shown to have a neutron excess and a marginally successful nucleosynthesis. They are composed of free nucleons,...
متن کامل5-10 GeV neutrinos from gamma-Ray burst fireballs
A gamma-ray burst fireball is likely to contain an admixture of neutrons. Inelastic collisions between differentially streaming protons and neutrons in the fireball produce nu(&mgr;) (nu;(&mgr;)) of approximately 10 GeV as well as nu(e) (nu;(e)) of approximately 5 GeV, which could produce approximately 7 events/year in km(3) detectors, if the neutron abundance is comparable to that of protons. ...
متن کاملHigh Energy Neutrinos from Cosmological Gamma-Ray Burst Fireballs
Observations suggest that g-ray bursts (GRBs) are produced by the dissipation of the kinetic energy of a relativistic fireball. We show that a large fraction, $10%, of the fireball energy is expected to be converted by photomeson production to a burst of ,1014 eV neutrinos. A km2 neutrino detector would observe at least several tens of events per year correlated with GRBs, and test for neutrino...
متن کاملFast Algorithms for Burst Detection
Events occur in every aspect of our lives. An unexpectedly large number of events occurring within some certain measurement (e.g. within some time duration or a spatial region) is called a burst, suggesting unusual behaviors or activities. Bursts come up in many natural and social processes. It is a challenging task to monitor the occurrence of bursts whose lasting duration is unknown in a fast...
متن کاملRadio scintillation of gamma-ray-burst afterglows ?
Stars twinkle to the eye through atmospheric turbulence, but planets, because of their larger angular size, do not. Similarly, scintillation due to the local interstellar medium will modulate the radio flux of gamma-ray-burst afterglows and may permit indirect measurements of their angular sizes. The amplitude of refractive scintillation is of order ten percent at ten gigahertz unless the sourc...
