Confirmation of the $\eps$ -- $\eiso$ (Amati) relation from the X-ray flash XRF 050416A observed by Swift/BAT
T. Sakamoto, L. Barbier, S. D. Barthelmy +10
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…
The Burst Alert Telescope (BAT) on the Swift MIDEX Mission
S. D. Barthelmy, L. M. Barbier, J. R. Cummings +12
The Burst Alert Telescope (BAT) is one of 3 instruments on the Swift MIDEX spacecraft to study gamma-ray bursts (GRBs). The BAT first detects the GRB and localizes the burst direct…
A short gamma-ray burst apparently asssociated with an elliptical galaxy at redshift z=0.225
N. Gehrels
Gamma Ray Bursts (GRBs) are bright, brief flashes of high energy photons that have fascinated scientists for 30 years. They come in two classes: long (>2 s), softspectrum bursts an…
Gamma-Ray Observations of a Giant Flare from The Magnetar SGR 1806-20
D. M. Palmer, S. Barthelmy, N. Gehrels +25
Magnetars comprise two classes of rotating neutron stars (Soft Gamma Repeaters (SGRs) and Anomalous X-ray Pulsars), whose X-ray emission is powered by an ultrastrong magnetic field…
