Earlier classification analyses found three types of gamma-ray bursts (short, long, and intermediate in duration) in the BATSE sample. Recent works have shown that these three groups are also present in the RHESSI and BeppoSAX databases. The duration distribution analysis of the bursts observed by the Swift satellite also favors the three-component model. In this paper, we extend the analysis of the Swift data with spectral information. We show, using the spectral hardness and duration…

Analysis of the observed and intrinsic durations of Swift/BAT gamma-ray bursts
Abstract The duration distribution of 947 GRBs observed by Swift /BAT, as well as its subsample of 347 events with measured redshift, allowing to examine the durations in both the observer and rest
The second Konus-Wind catalog of short gamma-ray bursts
In this catalog, we present the results of a systematic study of 295 short gamma-ray bursts (GRBs) detected by Konus-Wind (KW) from 1994 to 2010. From the temporal and spectral analyses of the
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.
Classification of Fermi Gamma-RAY Bursts
The Fermi GBM Catalog has been recently published. Previous classification analyses of the BATSE, RHESSI, BeppoSAX, and Swift databases found three types of gamma-ray bursts. Now we analyzed the GBM
Statistical Differences Between Swift Gamma-Ray Burst Classes Based on γ- and X-ray Observations
There are number of evidences that the gamma-ray bursts (GRBs) have a third group beside the short and long ones: the intermediate group. Although at this time, no reasonable physical explanation is
On the subclasses in Swift long gamma-ray bursts: A clue to different central engines
Analyzing light curves of a complete sample of bright Swift long gamma-ray bursts (LGRBs) of which the peak photon fluxes constructed with the bin width of 1 second in the Swift 15-350 keV energy
Gaussian-mixture-model-based cluster analysis of gamma-ray bursts in the BATSE catalog
Clustering is an important tool to describe gamma-ray bursts (GRBs). We analyzed the Final BATSE Catalog using Gaussian-mixture-models-based clustering methods for six variables (durations, peak
Distinction of groups of gamma-ray bursts in the BATSE catalog through fuzzy clustering
TLDR
F fuzzy clustering is conducted on the gamma-ray bursts from the final ‘Burst and Transient Source Experiment’ catalog to cross-check the significance of these new groups, andmeticulous study on individual bursts based on their memberships in the fuzzy clusters confirms the previously well-known three groups against the newly found five.
Analysis of the Duration–Hardness Ratio Plane of Gamma-Ray Bursts Using Skewed Distributions
It was recently shown that the $T_{90}-H_{32}$ distributions of gamma-ray bursts from CGRO/BATSE and Fermi/GBM are well described by a mixture of only two skewed components, making the presumed
A DISTINCT PEAK-FLUX DISTRIBUTION OF THE THIRD CLASS OF GAMMA-RAY BURSTS: A POSSIBLE SIGNATURE OF X-RAY FLASHES?
Gamma-ray bursts (GRBs) are the most luminous events in the universe. Going beyond the short-long classification scheme, we work in the context of three burst populations with the third group of

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 of
Identification of two classes of gamma-ray bursts
We have studied the duration distribution of the gamma-ray bursts of the first BATSE catalog. We find a bimodality in the distribution, which separates GRBs into two classes: short events (less than

Some articles based on the BATSE gamma‐ray burst (GRB) catalog claim the existence of a third population of GRBs, besides long and short. In this contribution we wanted to verify these claims with an

Using the derived gamma-ray burst (GRB) E peak and fluences from the complete BATSE 5B Spectral Catalog, we study the ensemble characteristics of the E peak-fluence relation for GRBs. This relation
