Investigation of the Kyoto's X-ray Astronomical SOIPIXs with Double-SOI Wafer for Reduction of Cross-talks
Shunichi Ohmura, Takeshi Go Tsuru, Takaaki Tanaka +10
We have been developing X-ray SOIPIXs, "XRPIX", for future X-ray astronomy satellites. XRPIX is equipped with a function of "event-driven readout", which allows us to readout signa…
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…
