Fireball Heated by Neutrinos
The fireball, the promising model of the gamma-ray burst (GRB), is an opaque radiation plasma, whose energy is significantly greater than its rest mass. We numerically simulate the evolution of the fireball heated by the neutrinoantineutrino annihilation process for the spherically symmetric case. We also derive analytical energy and momentum deposition rates via neutrino scattering with therma...
متن کاملCherenkov radiation by neutrinos
We discuss the Cherenkov process ν → νγ in the presence of a homogeneous magnetic field. The neutrinos are taken to be massless with only standard-model couplings. The magnetic field fulfills the dual purpose of inducing an effective neutrino-photon vertex and of modifying the photon dispersion relation such that the Cherenkov condition ω < |k| is fulfilled. For a field strength Bcrit = m 2 e/e...
متن کاملShocked by GRB 970228: the afterglow of a cosmological fireball
The location accuracy of the BeppoSAX Wide Field Cameras and acute ground-based followup have led to the detection of a decaying afterglow in X rays and optical light following the classical gamma-ray burst GRB 970228. The afterglow in X rays and optical light fades as a power law at all wavelengths. This behaviour was predicted for a relativistic blast wave that radiates its energy when it dec...
متن کاملResonances from a Hadronic Fireball
Production of φ(1020),Λ∗(1520) and K(892) resonances at the final stage of a heavy-ion collision is considered. It is shown that original momentum distributions and abundance of resonances formed during the process of heavy ion collision may differ significantly from their measured spectra and yields. Reconstruction probability of resonances decaying inside the fireball can be strongly suppress...
متن کاملCollective dynamics of the fireball
I analyse the identified single-particle pt spectra and two-pion Bose-Einstein correlations from RHIC. They indicate a massive transverse expansion and rather short lifetime of the system. The quantitative analysis in framework of the blast-wave model yields, however, unphysical results and suggests that the model may not be applicable in description of two-particle correlations. I then discuss...
