TL;DR
This paper presents a comprehensive catalog of 494 short gamma-ray bursts detected by Konus-Wind over ten years, including detailed temporal and spectral analyses, and discusses their classification and properties.
Contribution
It extends previous catalogs by adding ten years of data, providing detailed analyses and classifications of short GRBs, including those with extended emission and magnetar flares.
Findings
Distribution of burst durations and spectral parameters
Properties of bursts with extended emission
Classification into merger-origin and collapsar-origin groups
Abstract
In this catalog, we present the results of a systematic study of 199 short gamma-ray bursts (GRBs) detected by Konus-Wind between 2011 January 1 and 2021 August 31. The catalog extends the Second Catalog of short gamma-ray bursts covering the period 1994-2010 by ten years of data. The resulting Konus-Wind short GRB sample includes 494 bursts. From temporal and spectral analyses of the sample, we provide the burst durations, spectral lags, estimates of the minimum variability time scales, rise and decay times, the results of spectral fits with three model functions, the total energy fluences, and the peak energy fluxes of the bursts. We present statistical distributions of these parameters for the complete set of 494 short gamma-ray bursts detected in 1994-2021. We discuss in detail the properties of the bursts with extended emission in the context of the whole short GRB population.…
