Abstract
The dependence of Swift's detection sensitivity on a burst's temporal and spectral properties shapes the detected burst population. Using simplified models of the detector hardware and the burst trigger system I find that Swift is more sensitive to long, soft bursts than CGRO's BATSE, a reference detector because of the large burst database it accumulated. Thus Swift has increased sensitivity in the parameter space region into which time dilation and spectral redshifting shift high redshift bursts.Comment: 20 pages, 8 figures, Ap. J. in presKeywords
