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…
Bright X-ray Flares in Gamma-Ray Burst Afterglows
D. N. Burrows, P. Romano, A. Falcone +31
Gamma-ray burst (GRB) afterglows have provided important clues to the nature of these massive explosive events, providing direct information on the nearby environment and indirect…
GRB050223: A faint Gamma-Ray Burst discovered by Swift
K. L. Page, E. Rol, A. J. Levan +16
GRB050223 was discovered by the Swift Gamma-Ray Burst Explorer on 23 February 2005 and was the first Gamma-Ray Burst to be observed by both Swift and XMM-Newton. At the time of wri…
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…
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…
