Characterization of diffuse X-ray emission from IGR~J17448-3232: an implication of a line of sight merging activity
Shoko Watanabe, Shigeo Yamauchi, Kumiko K. Nobukawa +1
Results of the spectral analysis for the galaxy cluster IGR J17448-3232 are presented. The intracluster medium (ICM) in the central region (r<300", 320 kpc) has a high electron tem…
Neutral iron line in the supernova remnant IC 443 and implications for MeV cosmic rays
Kumiko K. Nobukawa, Arisa Hirayama, Aika Shimaguchi +3
We report a discovery of bright blob-like enhancements of an Fe I K line in the northwest and the middle of the supernova remnant (SNR) IC 443. The distribution of the line emis…
X-ray spectra of Sgr A East and diffuse X-ray background near the Galactic center
Akiko Ono, Hideki Uchiyama, Shigeo Yamauchi +3
This paper reports the analysis procedure and results of simultaneous spectral fits of the Suzaku archive data for Sagittarius (Sgr) A East and the nearby Galactic center X-ray emi…
