Confirmation of the E srcpeak – E iso ( Amati ) relation from the X - ray flash XRF 050416 A observed by Swift / BAT

Abstract

We report Swift Burst Alert Telescope (BAT) observations of the X-ray Flash (XRF) XRF 050416A. The fluence ratio between the 15-25 keV and 25-50 keV energy bands of this event is 1.5, thus making it the softest gamma-ray burst (GRB) observed by BAT so far. The spectrum is well fitted by the Band function with E peak of 15.0 +2.3 −2.7 keV. Assuming the… (More)
