The Ulysses Supplement to the BATSE 3B Catalog of Cosmic Gamma-Ray Bursts
We present Interplanetary Network localization information for 218 gamma-ray bursts in the 3rd BATSE catalog, obtained by analyzing the arrival times of these bursts at the Ulysses and Compton Gamma-Ray Observatory (CGRO) spacecraft. For any given burst observed by these two spacecraft, arrival time analysis (or “triangulation”) results in an annulus of possible arrival directions whose half-wi...
متن کاملBatse 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 کاملProbing the Small-scale Angular Distribution of Gamma-ray Bursts with Combined Batse/ulysses 4b Locations
We investigate the angular distribution of gamma-ray bursts using the largest catalog of welllocalized events that is currently available—combined BATSE/Ulysses burst locations. We present the preliminary spatial analysis of 415 BATSE/Ulysses bursts included in the BATSE 4B catalog. We find that the locations are consistent with largeand small-scale isotropy, with no significant clustering or r...
متن کاملThe Complete Spectral Catalog of Bright BATSE Gamma-Ray Bursts
We present a systematic spectral analysis of 350 bright GRBs observed with BATSE, with high spectral and temporal resolution. Our sample was selected from the complete set of 2704 BATSE GRBs, and included 17 short GRBs. To obtain well-constrained spectral parameters, four different photon models were fitted and the spectral parameters that best represent each spectrum were statistically determi...
