Description
We present a detailed study of the multi-wavelength properties of a sample of short GRBs with extended emission (EE) observed by Swift. The sample consists of 11 events, selected from the SBAT4 catalog by D’Avanzo et al., (2014), which was subsequently expanded to include events up to 2021. This sample exclusively contains only short GRBs with favorable observational conditions for the determination of redshifts from Earth and bright in terms of observed peak flux in the BAT energy band. The properties of the prompt emission (hardness ratio, spectral evolution), as well as the temporal behaviour of the X-ray afterglow phase are compared to the genuine short GRBs of the SBAT4 sample, and with a similarly selected complete sample of long Swift GRBs (BAT6), with the aim of identifying unique features that distinguish the class of short GRBs with EE.
