Discovery of the Highly-Neutronized Ejecta Clump with Enhanced Abundances of Titanium and Chromium in the Type Ia Supernova Remnant 3C 397
Yuken Ohshiro, Hiroya Yamaguchi, Shing-Chi Leung +7
The supernova remnant (SNR) 3C 397 is thought to originate from a Type Ia supernova (SN Ia) explosion of a near-Chandrasekhar-mass () progenitor, based on the enhanced…
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…
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…
Probing Cosmic Rays with Fe K Line Structures Generated by Multiple Ionization Process
Hiromichi Okon, Makoto Imai, Takaaki Tanaka +2
Supernova remnants (SNRs) have been regarded as major acceleration sites of Galactic cosmic rays. Recent X-ray studies revealed neutral Fe K line emission from dense gas in the…
Deep XMM-Newton Observations Reveal the Origin of Recombining Plasma in the Supernova Remnant W44
Hiromichi Okon, Takaaki Tanaka, Hiroyuki Uchida +8
Recent X-ray studies revealed over-ionized recombining plasmas (RPs) in a dozen mixed-morphology (MM) supernova remnants (SNRs). However, the physical process of the over-ionizatio…
The Origin of Recombining Plasma and the Detection of the Fe-K Line in the Supernova Remnant W28
Hiromichi Okon, Hiroyuki Uchida, Takaaki Tanaka +2
Overionized recombining plasmas (RPs) have been discovered from a dozen of mixed- morphology (MM) supernova remnants (SNRs). However their formation process is still under debate.…
