We examine the width of the gamma-ray burst (GRB) luminosity function through the distribution of GRB peak count rates, Cpeak, as detected by Burst and Transient Source Experiment (BATSE) (1993). In the context of Galactic corona spatial distribution models, we attempt to place constaints on the characteristic width of the luminosity function by comparing the observed intensity distribution with those produced by a range of density and luminosity functions. We find that the intrinsic width of… 
Internal Luminosity Distribution of Bright Gamma-Ray Bursts and its Relation to Duration and Spectral Hardness
We present first results from a comprehensive investigation into the distribution of luminosity within the 50 brightest cosmic gamma-ray bursts detected by the Burst and Transient Source Experiment
Luminosity function of GRBs
We attempt to constrain the luminosity function of Gamma Ray Bursts (GRBs) from the observed number count{flux relation and the afterglow redshift data. We assume three classes of luminosity
Inferring the Spatial and Energy Distribution of Gamma Ray Burst Sources. III. Anisotropic Models
We use Bayesian methods to analyze the distribution of gamma-ray burst intensities reported in the Third BATSE Catalog (3B catalog) of gamma-ray bursts, presuming the distribution of burst sources
The Cosmological Signatures and Flux Distribution of Gamma-Ray Bursts with a Broad Luminosity Distribution
Cosmological expansion cannot produce the reported correlations of the gamma-ray burst timescale and spectral energy with peak flux if the burst model reproduces the Burst and Transient Source
Constraints on the redshift and luminosity distributions of gamma-ray bursts in an Einstein-de Sitter universe
Two models of the gamma-ray burst population, one with a standard candle luminosity and one with a power-law luminosity distribution, are ?2-fitted to the union of two data sets: the differential
On the difference between the short and long gamma-ray bursts
We argue that the distributions of both the intrinsic fluence and the intrinsic duration of the γ-ray emission in gamma- ray bursts from the BATSE sample are well represented by log-normal
Relativistic Conic Beams and Spatial Distribution of Gamma-Ray Bursts
We study the statistics of gamma-ray bursts, assuming that gamma-ray bursts are cosmological and that they are beamed in the form of a conical jet with a large bulk Lorentz factor of ~100. In such a
The luminosity function and the rate of Swift's Gamma Ray Bursts
We invert directly the redshift-luminosity distribution of observed long Swift gamma-ray bursts (GRBs) to obtain their rate and luminosity function. Our best-fitting rate is described by a broken
Determination of gamma-ray burst properties through integral moment self-consistency analysis
Since April 1991, over 1000 GRBs have been observed with the Burst and Transient Source Experiment (BATSE) on board the Compton Gamma Ray Observatory (GRO), providing unprecedented information on the
