Single event effect characterization of the mixed-signal ASIC developed for CCD camera in space use
Hiroshi Nakajima, Mari Fujikawa, Hideki Mori +10
We present the single event effect (SEE) tolerance of a mixed-signal application-specific integrated circuit (ASIC) developed for a charge-coupled device camera onboard a future X-…
Possible Charge-Exchange X-Ray Emission in the Cygnus Loop Detected with Suzaku
Satoru Katsuda, Hiroshi Tsunemi, Koji Mori +8
X-ray spectroscopic measurements of the Cygnus Loop supernova remnant indicate that metal abundances throughout most of the remnant's rim are depleted to about 0.2 times the solar…
First Detection of Ar-K Line Emission from the Cygnus Loop
H. Uchida, H. Tsunemi, N. Tominaga +5
We observed the Cygnus Loop with XMM-Newton (9 pointings) and Suzaku (32 pointings) between 2002 and 2008. The total effective exposure time is 670.2 ks. By using all of the availa…
Suzaku X-Ray Imaging and Spectroscopy of Cassiopeia A
Y. Maeda, Y. Uchiyama, A. Bamba +26
Suzaku X-ray observations of a young supernova remnant, Cassiopeia A, were carried out. K-shell transition lines from highly ionized ions of various elements were detected, includi…
Line-of-sight Shell Structure of the Cygnus Loop
Hiroyuki Uchida, Hiroshi Tsunemi, Satoru Katsuda +3
We conducted a comprehensive study on the shell structure of the Cygnus Loop using 41 observation data obtained by the Suzaku and the XMM-Newton satellites. To investigate the deta…
The Ejecta Distributions of the Heavy Elements in the Cygnus Loop
Hiroyuki Uchida, Hiroshi Tsunemi, Satoru Katsuda +2
We analyzed the metal distribution of the Cygnus Loop using 14 and 7 pointings observation data obtained by the \textit{Suzaku} and the \textit{XMM-Newton} observatories. The spect…
