GRB 080319B: A Naked-Eye Stellar Blast from the Distant Universe

J. L. Racusin, S. V. Karpov, M. Sokolowski +81

Long duration gamma-ray bursts (GRBs) release copious amounts of energy across the entire electromagnetic spectrum, and so provide a window into the process of black hole formation…

Global Properties of X-Ray Flashes and X-Ray-Rich Gamma-Ray Bursts Observed by Swift

T. Sakamoto, D. Hullinger, G. Sato +14

We describe and discuss the spectral and temporal characteristics of the prompt emission and X-ray afterglow emission of X-ray flashes (XRFs) and X-ray-rich gamma-ray bursts (XRRs)…

The First Swift BAT Gamma-Ray Burst Catalog

T. Sakamoto, S. D. Barthelmy, L. Barbier +13

We present the first Swift Burst Alert Telescope (BAT) catalog of gamma-ray bursts (GRBs), which contains bursts detected by the BAT between 2004 December 19 and 2007 June 16. This…

The Post-Burst Awakening of the Anomalous X-ray Pulsar in Westerlund 1

G. L. Israel, S. Campana, S. Dall'Osso +4

On September 21, 2006, an intense (~10^39 erg/s) and short (20 ms) burst was detected by Swift BAT at a position consistent with that of the candidate Anomalous X-ray Pulsar, CXOU…

Periodicities in X-ray Binaries from Swift/BAT Observations

R. Corbet, C. Markwardt, L. Barbier +8

The Burst Alert Telescope (BAT) on board Swift has accumulated extensive light curves for 265 sources (not including GRBs) in the energy range 14 to 200 keV. We present here a summ…

The nature of the outflow in gamma-ray bursts

P. Kumar, E. McMahon, A. Panaitescu +9

The Swift satellite has enabled us to follow the evolution of gamma-ray burst (GRB) fireballs from the prompt gamma-ray emission to the afterglow phase. The early x-ray and optical…
