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 Long-term Radiative Evolution of Anomalous X-ray Pulsar 1E 2259+586 after its 2002 Outburst
Weiwei Zhu, Victoria M. Kaspi, Peter M. Woods +3
We present an analysis of five X-ray Multi-Mirror Mission (XMM) observations of the anomalous X-ray pulsar (AXP) 1E 2259+586 taken in 2004 and 2005 during its relaxation following…
Discovery of 442-Hz Pulsations from an X-ray Source in the Globular Cluster NGC 6440
Fotis P. Gavriil, Tod E. Strohmayer, Jean H. Swank +1
We report on the serendipitous discovery of a 442-Hz pulsar during a Rossi X-ray Timing Explorer (RXTE) observation of the globular cluster NGC 6440. The oscillation is detected fo…
Evidence of Exponential Decay Emission in the Swift Gamma-ray Bursts
T. Sakamoto, J. E. Hill, R. Yamazaki +6
We present a systematic study of the steep decay emission from gamma-ray bursts (GRBs) observed by the Swift X-Ray Telescope (XRT). In contrast to the analysis described in recent…
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…
X-ray and Near-IR Variability of the Anomalous X-ray Pulsar 1E 1048.1-5937: From Quiescence Back to Activity
Cindy R. Tam, Fotis P. Gavriil, Rim Dib +3
(Abridged) We report on new and archival X-ray and near-infrared observations of the anomalous X-ray pulsar 1E 1048.1-5937 performed between 2001-2007 with RXTE, CXO, Swift, HST, a…
