X-ray Performance of Back-Side Illuminated Type of Kyoto's X-ray Astronomical SOI Pixel Sensor, XRPIX
Makoto Itou, Takeshi Go Tsuru, Takaaki Tanaka +11
We have been developing X-ray SOI pixel Sensors, called "XRPIX", for future X-ray astronomy satellites that enable us to observe in the wide energy band of 0.5-40 keV. Since XRPIXs…
Improvement of Spectroscopic Performance using a Charge-sensitive Amplifier Circuit for an X-Ray Astronomical SOI Pixel Detector
Ayaki Takeda, Takeshi Go Tsuru, Takaaki Tanaka +13
We have been developing monolithic active pixel sensors series, named "XRPIX," based on the silicon-on-insulator (SOI) pixel technology, for future X-ray astronomical satellites. T…
Galactic-Center Hyper-Shell Model for the North Polar Spurs
Y. Sofue, A. Habe, J. Kataoka +5
The bipolar-hyper shell (BHS) model for the North Polar Spurs (NPS-E, -W, and Loop I) and counter southern spurs (SPS-E and -W) is revisited based on numerical hydrodynamical simul…
Global structure of isothermal X-ray emission along the Fermi bubbles
J. Kataoka, M. Tahara, T. Totani +4
In our previous works (Kataoka et al. 2013, Tahara et al. 2015), we found absorbed thermal X-ray plasma with kT ~ 0.3 keV observed ubiquitously near the edges of the Fermi bubbles…
Suzaku X-ray Observations of the Fermi Bubbles: Northernmost Cap and Southeast Claw Discovered with MAXI-SSC
M. Tahara, J. Kataoka, Y. Takeuchi +8
We report on Suzaku observations of large-scale X-ray structures possibly related with the Fermi Bubbles obtained in 2013 with a total duration of ~ 80 ks. The observed regions wer…
Metal Enrichment in the Fermi Bubbles as a Probe of Their Origin
Yoshiyuki Inoue, Shinya Nakashima, Masaya Tahara +4
The Fermi bubbles are gigantic gamma-ray structures in our Galaxy. The physical origin of the bubbles is still under debate. The leading scenarios can be divided into two categorie…
