Description
The existence of bursts of astrophysical gamma rays with durations less than tens of microseconds are essentially unprobed. It was recently proposed that the VERITAS array could detect such bursts with an appropriate analysis of its archival data. In this paper, we demonstrate the feasibility of a search for these bursts and devise a data-analysis protocol to carry it out. We perform realistic air-shower and VERITAS-telescope simulations to accurately predict the images of sub-ten-microsecond gamma-ray bursts as seen in VERITAS. We propose discrimination criteria based on the properties of these images, optimized on a subset of the VERITAS data, and show that sufficient signal-background rejection efficiency is achievable.
