Maxim Barkov and Alexei Pozanenko , Model of the extended emission of short gamma-ray bursts , Mon . ... The existence of extended emission (EE) is an intriguing property of short-duration gammaray bursts, because the nature of the EE is still unclear. ... We consider short duration gamma-ray bursts, emphasizing the common properties of both short bursts and short bursts with EE. ... Our proposed model is a plausible mechanism for short-duration burst energization . ...
