Single Event Tolerance of X-ray SOI Pixel Sensors
Kouichi Hagino, Mitsuki Hayashida, Takayoshi Kohmura +19
We evaluate the single event tolerance of the X-ray silicon-on-insulator (SOI) pixel sensor named XRPIX, developed for the future X-ray astronomical satellite FORCE. In this work,…
Discovery of Year-Scale Time Variability from Thermal X-ray Emission in Tycho's Supernova Remnant
Masamune Matsuda, Hiroyuki Uchida, Takaaki Tanaka +2
Mechanisms of particle heating are crucial to understanding the shock physics in supernova remnants (SNRs). However, there has been little information on time variabilities of ther…
Particle acceleration controlled by ambient density in the southwestern rim of RCW 86
Hiromasa Suzuki, Satoru Katsuda, Takaaki Tanaka +3
Particle acceleration physics at supernova remnant (SNR) shocks is one of the most intriguing problems in astrophysics. SNR RCW~86 provides a suitable environment for understanding…
Spatially resolved study of the SS 433/W50 west region with Chandra: X-ray structure and spectral variation of non-thermal emission
Kazuho Kayama, Takaaki Tanaka, Hiroyuki Uchida +6
The X-ray binary SS 433, embedded in the W50 nebula (or supernova remnant W50), shows bipolar jets that are ejected with mildly relativistic velocities, and extend toward the east…
X-ray Radiation Damage Effects on Double-SOI Pixel Detectors for the Future Astronomical Satellite "FORCE"
Masatoshi Kitajima, Kouichi Hagino, Takayoshi Kohmura +20
We have been developing the monolithic active pixel detector "XRPIX" onboard the future X-ray astronomical satellite "FORCE". XRPIX is composed of CMOS pixel circuits, SiO2 insulat…
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…
