ISAI: Investigating Solar Axion by Iron-57
Tomonori Ikeda, Toshihiro Fujii, Takeshi Go Tsuru +9
The existence of the axion is a unique solution for the strong CP problem, and the axion is one of the most promising candidates of the dark matter. Investigating Solar Axion by Ir…
Charge Exchange X-ray Emission Detected in Multiple Shells of Supernova Remnant G296.1-0.5
Yukiko Tanaka, Hiroyuki Uchida, Takaaki Tanaka +5
Recent high-resolution X-ray spectroscopy revealed possible presence of charge exchange (CX) X-ray emission in supernova remnants (SNRs). Although CX is expected to take place at o…
High resolution X-ray study of supernova remnant J0453.66829 with unusually high forbidden-to-resonance ratio
Yosuke Koshiba, Hiroyuki Uchida, Takaaki Tanaka +3
Recent high-resolution X-ray spectroscopy has revealed that several supernova remnants (SNRs) in the Large Magellanic Cloud (LMC) show unusually high forbidden-to-resonance ()…
Low-Energy X-ray Performance of SOI Pixel Sensors for Astronomy, "XRPIX"
Ryota Kodama, Takeshi Go Tsuru, Takaaki Tanaka +17
We have been developing a new type of X-ray pixel sensors, "XRPIX", allowing us to perform imaging spectroscopy in the wide energy band of 1-20 keV for the future Japanese X-ray sa…
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…
Radiation Damage Effects on Double-SOI Pixel Sensors for X-ray Astronomy
Kouichi Hagino, Keigo Yarita, Kousuke Negishi +19
The X-ray SOI pixel sensor onboard the FORCE satellite will be placed in the low earth orbit and will consequently suffer from the radiation effects mainly caused by geomagneticall…
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…
Temporal and Spatial Variation of Synchrotron X-ray Stripes in Tycho's Supernova Remnant
Masamune Matsuda, Takaaki Tanaka, Hiroyuki Uchida +2
The synchrotron X-ray "stripes" discovered in Tycho's supernova remnant (SNR) have been attracting attention since they may be evidence for proton acceleration up to PeV. We analyz…
Evidence for Resonance Scattering in the X-ray Grating Spectrum of the Supernova Remnant N49
Yuki Amano, Hiroyuki Uchida, Takaaki Tanaka +2
Resonance scattering (RS) is an important process in astronomical objects, because it affects measurements of elemental abundances and distorts surface brightness of the object. It…
Measurement of Charge Cloud Size in X-ray SOI Pixel Sensors
Kouichi Hagino, Kenji Oono, Kousuke Negishi +20
We report on a measurement of the size of charge clouds produced by X-ray photons in X-ray SOI (Silicon-On-Insulator) pixel sensor named XRPIX. We carry out a beam scanning experim…
