Gamma-Ray Bursts (GRBs) are traditionally divided to long and short according to their durations (≶ 2 sec). It was generally believed that this reflects a different physical origin: Collapsars (long) and non-Collapsars (short). We have recently shown that the duration distribution of Collapsars is flat, namely independent of the duration, at short durations. Using this model for the distribution of Collapsars we determine the duration distribution of non-Collapsars and estimate the probability… Expand
The rate, luminosity function and time delay of non-Collapsar short GRBs
We estimate the rate and the luminosity function of short (hard) Gamma-Ray Bursts (sGRBs) that are non-Collapsars, using the peak fluxes and redshifts of BATSE, Swift and Fermi GRBs. FollowingExpand
Distributions of pseudo-redshifts and durations (observed and intrinsic) of Fermi GRBs
Ever since the insightful analysis of the durations of gamma-ray bursts (GRBs) by Kouveliotou et al. (Astrophys. J. Lett. 413:101, 1993), GRBs have most often been classified into two populations:Expand
Are short Gamma Ray Bursts similar to long ones
Abstract The apparent separation of short and long Gamma-Ray Bursts (GRBs) in the hardness ratio vs duration plot has been considered as a direct evidence of the difference between these twoExpand
On the Composition of GRBs' Collapsar Jets
The duration distribution of long gamma-ray bursts (GRBs) reveals a plateau at durations shorter than ∼20 s (in the observer frame) and a power-law decline at longer durations. Such a plateau arisesExpand
On the observed duration distribution of gamma-ray bursts from collapsars
The duration of the prompt emission of long gamma-ray bursts is generally considered to be fairly similar to the duration of the activity of the engine in the center of the progenitor star. Here, weExpand
Classification of gamma-ray burst durations using robust model-comparison techniques
Gamma-Ray Bursts (GRBs) have been conventionally bifurcated into two distinct categories dubbed “short” and “long”, depending on whether their durations are less than or greater than two secondsExpand
Statistical study of observed and intrinsic durations among BATSE and Swift/BAT GRBs
Studies of BATSE bursts (Kouveliotou et al. 1993) have resulted in the widespread adoption of a two-group categorization: long bursts (those with durations ≥2 seconds) and short bursts (those withExpand
Collapsar γ-ray bursts: how the luminosity function dictates the duration distribution
Jets in long-duration $\gamma$-ray bursts (GRBs) have to drill through the collapsing star in order to break out of it and produce the $\gamma$-ray signal while the central engine is still active. IfExpand
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
Observational evidence for mass ejection accompanying short gamma ray bursts
The plateau in the duration distribution of long Gamma-Ray Bursts (LGRBs) provides a direct observational evidence for the Collapsar model. The plateau reflects the fact that the observed durationExpand
