Batse Observations of Gamma-ray Bursts
Gamma-ray bursts are currently perhaps the most mysterious phenomenon in the universe, once thought to originate on neutron stars in the plane of our galaxy. The BATSE instrument on CGRO does not observe the key prediction of this hypothesis; the data favor a population of sources either at cosmological distances or in an extended galactic halo. In this review, I present the observations upon w...
متن کاملTime Dilation of BATSE Gamma-ray Bursts
We perform several nonparametric correlation tests on the BATSE 3B data to search for evidence of cosmological time dilation. These tests account for the effects of data truncation due to threshold effects in both limiting brightness and limiting duration, enabling us to utilize a larger number of bursts than in previous analyses. We find little significant evidence for correlation between vari...
متن کاملNeutrinos From Individual Gamma-Ray Bursts in the BATSE Catalog
We estimate the neutrino emission from individual gamma-ray bursts observed by the BATSE detector on the Compton Gamma-Ray Observatory. Neutrinos are produced by photoproduction of pions when protons interact with photons in the region where the kinetic energy of the relativistic fireball is dissipated allowing the acceleration of electrons and protons. We also consider models where neutrinos a...
متن کاملDuration Distributions of Bright and Dim Batse Gamma-ray Bursts
We have measured the T90 and T50 durations of bright and dim gamma-ray bursts (GRBs) detected by the Compton Gamma Ray Observatory’s Burst and Transient Source Experiment (BATSE). The T90 (T50) duration is defined as the interval over which 5% (25%) to 95% (75%) of the burst counts accumulate. Out of 775 bursts observed by BATSE, 159 bursts were analyzed; bursts with durations shorter than 1.5 ...
متن کاملRedshift indicators for gamma - ray bursts
— The measure of the distances and luminosities of gamma-ray bursts (GRBs) led to the discovery that many GRB properties are strongly correlated with their intrinsic luminosity, leading to the construction of reliable luminosity indicators. These GRB luminosity indicators have quickly found applications, like the construction of 'pseudo-redshifts', or the measure of luminosity distances, which ...
