Experimental studies on the charge transfer inefficiency of CCD developed for the soft X-ray imaging telescope Xtend aboard the XRISM satellite
Yoshiaki Kanemaru, Jin Sato, Toshiyuki Takaki +38
We present experimental studies on the charge transfer inefficiency (CTI) of charge-coupled device (CCD) developed for the soft X-ray imaging telescope, Xtend, aboard the XRISM sat…
Intrusion of MeV-TeV Cosmic-Rays into Molecular Clouds Studied by Ionization, the Neutral Iron Line, and Gamma-Rays
Yutaka Fujita, Kumiko K. Nobukawa, Hidetoshi Sano
Low-energy (~MeV) cosmic rays (CRs) ionize molecular clouds and create the neutral iron line (Fe I Kα) at 6.4 keV. On the other hand, high-energy (>~ GeV) CRs interact with the den…
Optical Blocking Performance of CCDs Developed for the X-ray Astronomy Satellite XRISM
Hiroyuki Uchida, Takaaki Tanaka, Yuki Amano +43
We have been developing P-channel Charge-Coupled Devices (CCDs) for the upcoming X-ray Astronomy Satellite XRISM, planned to be launched in 2021. While the basic design of the CCD…
Discovery of recombining plasma associated with the candidate supernova remnant G189.6+3.3 with Suzaku
Shigeo Yamauchi, Moe Oya, Kumiko K. Nobukawa +1
We present the results of an X-ray spectral analysis of the northeast region of the candidate supernova remnant G189.6+3.3 with Suzaku. K-shell lines from highly ionized Ne, Mg, Si…
X-ray emission from the mixed-morphology supernova remnant HB 9
Mariko Saito, Shigeo Yamauchi, Kumiko K. Nobukawa +2
We present the results of a spectral analysis of the central region of the mixed-morphology supernova remnant HB 9. A prior Ginga observation of this source detected a hard X-ray c…
Discovery of annular X-ray emission centered on MAXI J1421-613: Dust-scattering X-rays?
Kumiko K. Nobukawa, Masayoshi Nobukawa, Shigeo Yamauchi
We report the discovery of an annular emission of 3'-9' radius around the center of a transient source, an X-ray burster MAXI J1421-613, in the Suzaku follow-up analysis. The…
