THE nature of the sources of cosmic γ-ray bursts is a long-standing problem in astrophysics. Lack of knowledge of their true spatial distribution and of their intrinsic brightness has hampered theoretical understanding of these enigmatic events. The Burst and Transient Source Experiment on the Compton Gamma-Ray Observatory has been detecting bursts at the rate of about one a day, and we report here an analysis of 153 events. The number versus intensity distribution does not follow the –3/2… 
Evidence for anisotropy in the distribution of short-lived gamma-ray bursts
Measurements of the two-point angular correlation function w(θ) for 407 short gamma-ray bursts collected in the Current BATSE Catalogue reveal a ∼2σ deviation from isotropy on angular scales 0 ∼
The intrinsic luminosity of γ-ray bursts and their host galaxies
THE Burst and Transient Source Experiment (BATSE) on the Compton Gamma-Ray Observatory has shown that, although γ-ray bursts are distributed isotropically on the sky, there is an apparent dearth of
Two-population model for the sources of γ-ray bursts
RECENT measurements by the Burst and Transient Source Experiment (BATSE) on the Compton Gamma Ray Observatory Satellite suggest that the distribution of γ-ray burst sources is isotropic about the
Are There Gamma-Ray Burst Sources at Cosmological Distances?
The experimental data for gamma-ray bursts are reviewed and discussed from the point of view the localization of sources. The spectral features in the 60 keV and 400 keV energy ranges, as well the
Gamma‐ray bursts: Observational overview
Gamma‐ray bursts remain one of the greatest mysteries in astrophysics in spite of recent observational advances and intense theoretical work. Many properties of bursts which were known 20 years ago
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 Fluence Distribution of Gamma-Ray Bursts
In the use and interpretation of log N-log S distributions for gamma-ray bursts, burst peak flux has typically been used for S. We consider here the use of the fluence as a measure of S, which may be
Statistics of the gamma-ray burst population.
Gamma-Ray Bursters are surprising sources of transient high energy emission. Twenty years after their discovery, the nature of these objects remains unknown and is one of the mysteries of high energy

Statistical evidence for a galactic origin of gamma-ray bursts
ASTRONOMICAL bursts of gamma-rays (GRBs) were first discovered 20 years ago, and ∼ 100 are recorded every year by satellite-borne instruments. Bursts last for at most a few seconds, recur only on a
A test of the galactic origin of gamma-ray bursts
Models in which gamma-ray bursters are young neutron stars may be difficult to reconcile with the apparently isotropic distribution of observed bursts. To justify this statement, the distribution of
Application of the V/V(max) test to gamma-ray bursts
The V/V(max) test applied to a well-defined sample of objects provides a quantitative test for the uniformity of the space distribution of the parent population of the objects. The application of
