Suzaku Observation of the Anomalous X-ray Pulsar CXOU J164710.2--455216
Sachindra Naik, Tadayasu Dotani, Nobuyuki Kawai +11
Suzaku TOO observation of the anomalous X-ray pulsar CXOU J164710.2-455216 was performed on 2006 September 23--24 for a net exposure of 38.8 ks. During the observation, the XIS was…
Swift captures the spectrally evolving prompt emission of GRB 070616
R. L. C. Starling, P. T. O'Brien, R. Willingale +14
The origins of Gamma-ray Burst prompt emission are currently not well understood and in this context long, well-observed events are particularly important to study. We present the…
Observations of the Prompt Gamma-Ray Emission of GRB 070125
Eric C. Bellm, Kevin Hurley, Valentin Pal'shin +17
The long, bright gamma-ray burst GRB 070125 was localized by the Interplanetary Network. We present light curves of the prompt gamma-ray emission as observed by Konus-WIND, RHESSI,…
Uniting the Quiescent Emission and Burst Spectra of Magnetar Candidates
Yujin E. Nakagawa, Atsumasa Yoshida, Kazutaka Yamaoka +1
Spectral studies of quiescent emission and bursts of magnetar candidates using XMM-Newton, Chandra and Swift data are presented. Spectra of both the quiescent emission and the burs…
Spectral evolution of GRB 060904A observed with Swift and Suzaku -- Possibility of Inefficient Electron Acceleration
Daisuke Yonetoku, Sachiko Tanabe, Toshio Murakami +39
We observed an X-ray afterglow of GRB 060904A with the Swift and Suzaku satellites. We found rapid spectral softening during both the prompt tail phase and the decline phase of an…
HETE-2 Observations of the X-Ray Flash XRF 040916
Makoto Arimoto, Nobuyuki Kawai, Atsumasa Yoshida +43
A long X-ray flash was detected and localized by the instruments aboard the High Energy Transient Explorer II (HETE-2) at 00:03:30 UT on 2004 September 16. The position was reporte…
A Comprehensive Study of Short Bursts from SGR 1806-20 and SGR 1900+14 Detected by HETE-2
Yujin E. Nakagawa, Atsumasa Yoshida, Kevin Hurley +20
We present the results of temporal and spectral studies of the short burst (less than a few hundred milliseconds) from the soft gamma repeaters (SGRs) 1806-20 and 1900+14 using the…
