We have studied the complete randomness of the angular distribution of gamma-ray bursts (GRBs) detected by the Burst and Transient Source Experiment (BATSE). Because GRBs seem to be a mixture of objects of different physical nature, we divided the BATSE sample into five subsamples (short1, short2, intermediate, long1, long2) based on their durations and peak fluxes, and we studied the angular distributions separately. We used three methods, Voronoi tesselation, minimal spanning tree and… Expand

Is sky distribution of gamma-ray bursts random?
We investigate the full randomness of the angular distribution of gamma-ray bursts (GRBs) detected by the BATSE (the Burst and Transient Source Experiment). We divided the BATSE sample into 5Expand
Testing the Isotropic Universe Using the Gamma-Ray Burst Data of Fermi/GBM
The sky distribution of Gamma-Ray Bursts (GRBs) has been intensively studied by various groups for more than two decades. Most of these studies test the isotropy of GRBs based on their sky numberExpand
Testing the anisotropy in the angular distribution of $Fermi$/GBM gamma-ray bursts
Gamma-ray bursts (GRBs) were confirmed to be of extragalactic origin due to their isotropic angular distribution, combined with the fact that they exhibited an intensity distribution that deviatedExpand
On the connection of gamma-ray bursts and X-ray flashes in the BATSE and RHESSI databases
Classification of gamma-ray bursts (GRBs) into groups has been intensively studied by various statistical tests in previous years. It has been suggested that there was a distinct group of GRBs,Expand
Update on testing the isotropy of the properties of gamma-ray bursts
Previously, we proposed a novel method to inspect the isotropy of the properties of gamma-ray bursts (GRBs), such as their duration, fluences and peak fluxes at various energy bands and differentExpand
A search for Galactic transients disguised as gamma-ray bursts
A significant fraction of cosmological gamma-ray bursts (GRBs) are characterised by a fast rise and exponential decay (FRED) temporal structure. This is not a distinctive feature of this class, sinceExpand
Cosmological effects on the observed flux and fluence distributions of gamma-ray bursts: Are the most distant bursts in general the faintest ones?
Context. Several claims have been put forward that an essential fraction of long-duration BATSE gamma-ray bursts should lie at redshifts larger than 5. This point-of-view follows from the naturalExpand
Searching for differences in Swift's intermediate GRBs
Context. Gamma-ray bursts are usually classified in terms their high-energy emission into either short-duration or long-duration bursts, which presumably reflect two different types of progenitors.Expand
z = 1 multifractality of Swift short GRBs?
Aims. We analyze and characterize the angular distribution of selected samples of gamma ray bursts (GRBs) from BATSE and Swift data to confirm that the division into two classes of short- andExpand
On the limit between short and long GRBs
Two classes of GRBs have been identified thus far without doubt and are prescribed to different physical scenarios—NS-NS or NS-BH mergers, and collapse of massive stars, for short and long GRBs,Expand


A Remarkable Angular Distribution of the Intermediate Subclass of Gamma-Ray Bursts
We develop a method of testing the null hypothesis of intrinsic randomness in the angular distribution of gamma-ray bursts collected in the Current BATSE Catalog. The method is a modified version ofExpand
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-normalExpand
An intrinsic anisotropy in the angular distribution of gamma-ray bursts
The anisotropy of the sky distribution of 2025 gamma-ray bursts (GRBs) collected in Current BATSE catalog is confirmed. It is shown that the quadrupole term being proportional to similar to sin 2bExpand
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 ∼Expand
An origin in the local Universe for some short γ-ray bursts
Gamma-ray bursts (GRBs) divide into two classes: ‘long’, which typically have initial durations of T90 > 2 s, and ‘short’, with durations of T90 < 2 s (where T90 is the time to detect 90% of theExpand
Three Types of Gamma-Ray Bursts
A multivariate analysis of gamma-ray burst (GRB) bulk properties is presented to discriminate between distinct classes of GRBs. Several variables representing burst duration, fluence, and spectralExpand

The final chapter in the long-standing mystery of the γ-ray bursts (GRBs) centres on the origin of the short-hard class of bursts, which are suspected on theoretical grounds to result from theExpand
A further study of the BATSE Gamma-Ray Burst duration distribution
Two classes of gamma-ray bursts have been identified so far, characterized by durations shorter and longer than about 2 s. In 1998 two independent papers indicated the existence of the third class ofExpand
The first BATSE gamma-ray burst catalog

Anisotropy in the angular distribution of the long gamma-ray bursts?
The gamma-ray bursts detected by the BATSE instrument may be separated into "short", "intermediate" and "long" subgroups. Previous statistical tests found an anisotropic sky-distribution on largeExpand
