Epeak estimator for Gamma-Ray Bursts Observed by the Swift Burst Alert Telescope
T. Sakamoto, G. Sato, L. Barbier +13
We report a correlation based on a spectral simulation study of the prompt emission spectra of gamma-ray bursts (GRBs) detected by the Swift Burst Alert Telescope (BAT). The correl…
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…
Long-term X-ray changes in the emission from the anomalous X-ray pulsar 4U 0142+61
M. E. Gonzalez, R. Dib, V. M. Kaspi +3
We present results obtained from X-ray observations of the anomalous X-ray pulsar (AXP) 4U 0142+61 taken between 2000-2007 using XMM-Newton, Chandra and Swift. In observations take…
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…
