ABSTRACT

In this catalog, we present the results of a systematic study of 199 short gamma-ray bursts (GRBs) detected by Konus-Wind (KW) from 2011 to 2021. From the temporal and spectral analyses of the sample, we provide the burst durations, the spectral lags, the results of spectral fits with three model functions, the total energy fluences and the peak energy fluxes of the bursts. We discuss evidence found for an additional power-law spectral component and the presence of extended emission in a fraction of the KW short GRBs. Finally, we discuss the results. obtained in the context of the Type I (merger-origin), the Type II (collapsar-origin) and the magnetar giant flare. classifications.
