Performance of SOI Pixel Sensors Developed for X-ray Astronomy
Takaaki Tanaka, Takeshi Go Tsuru, Hiroyuki Uchida +24
We have been developing monolithic active pixel sensors for X-rays based on the silicon-on-insulator technology. Our device consists of a low-resistivity Si layer for readout CMOS…
Evidence for Rapid Adiabatic Cooling as an Origin of the Recombining Plasma in the Supernova Remnant W49B Revealed by NuSTAR Observations
Hiroya Yamaguchi, Takaaki Tanaka, Daniel R. Wik +8
X-ray observations of supernova remnants (SNRs) in the last decade have shown that the presence of recombining plasmas is somewhat common in a certain type of object. The SNR W49B…
X-ray response evaluation in subpixel level for X-ray SOI pixel detectors
Kousuke Negishi, Takayoshi Kohmura, Kouichi Hagino +21
We have been developing event-driven SOI Pixel Detectors, named `XRPIX' (X-Ray soiPIXel) based on the silicon-on-insulator (SOI) pixel technology, for the future X-ray astronomical…
Proton Radiation Damage Experiment for X-Ray SOI Pixel Detectors
Keigo Yarita, Takayoshi Kohmura, Kouichi Hagino +23
In low earth orbit, there are many cosmic rays composed primarily of high energy protons. These cosmic rays cause surface and bulk radiation effects, resulting in degradation of de…
NuSTAR Detection of Nonthermal Bremsstrahlung from the Supernova Remnant W49B
Takaaki Tanaka, Hiroya Yamaguchi, Daniel R. Wik +10
We report on NuSTAR observations of the mixed morphology supernova remnant (SNR) W49B, focusing on its nonthermal emission. Whereas radio observations as well as recent gamma-ray o…
Suzaku X-ray observations of the mixed-morphology supernova remnant CTB 1
Miho Katsuragawa, Shinya Nakashima, Hideaki Matsumura +6
We present an X-ray study of the mixed-morphology supernova remnant CTB 1 (G116.9+0.2) observed with Suzaku. The 0.6-2.0 keV spectra in the northeast breakout region of CTB 1 are w…
