Study of Nature of Corona in Narrow Line Seyfert 1 Galaxies
Hiroshi H. Idogaki, Shunichi Ohmura, Hiroaki Takahashi +7
We study X-ray spectra of four Narrow Line Seyfert 1 galaxies (NLS1s), Mrk 110, SWIFT J2127.4+5654, IGR J16185-5928, and WKK 4438, using Suzaku and NuSTAR data. The spectra of the…
Suzaku Discovery of Fe K-Shell Line from the O-Rich SNR G292.0+1.8
Fumiyoshi Kamitsukasa, Katsuji Koyama, Hiroshi Tsunemi +7
We report the Suzaku/XIS results of the Galactic oxygen-rich supernova remnant (SNR), G292.0+1.8, a remnant of a core-collapse supernova. The X-ray spectrum of G292.0+1.8 consists…
Line-of-sight Shell Structure of the Cygnus Loop
Hiroyuki Uchida, Hiroshi Tsunemi, Satoru Katsuda +3
We conducted a comprehensive study on the shell structure of the Cygnus Loop using 41 observation data obtained by the Suzaku and the XMM-Newton satellites. To investigate the deta…
Suzaku Observation of the Diffuse X-Ray Emission from the Open Cluster Westerlund 2: a Hypernova Remnant?
Yutaka Fujita, Kiyoshi Hayashida, Hiroaki Takahashi +1
We present the analysis of Suzaku observations of the young open cluster Westerlund 2, which is filled with diffuse X-ray emission. We found that the emission consists of three the…
