Suzaku Spectroscopy of an X-Ray Reflection Nebula and a New Supernova Remnant Candidate in the Sgr B1 Region
Masayoshi Nobukawa, Takeshi Go Tsuru, Yojiro Takikawa +7
We made a 100 ks observation of the Sagittarius (Sgr) B1 region at (l, b) = (0.5, -0.1) near to the Galactic center (GC) with the Suzaku/XIS. Emission lines of S XV, Fe I, Fe XXV,…
Discovery of Extended X-Ray emission from the unidentified TeV source HESS J1614-518 using the Suzaku Satellite
Hironori Matsumoto, Hideki Uchiyama, Makoto Sawada +8
We report the Suzaku results of HESS J1614-518, which is the brightest extended TeV gamma-ray source discovered in the Galactic plane survey conducted using the H.E.S.S. telescope.…
A Time-Variable X-Ray Echo: Indications of a Past Flare of the Galactic-Center Black Hole
Katsuji Koyama, Tatsuya Inui, Hironori Matsumoto +1
A time-variability study of the neutral iron line flux at 6.40keV in the Sgr B2 region from data of Suzaku and Chandra is presented. The highly ionized iron line at 6.68keV is due…
Development of an n-channel CCD, CCD-NeXT1, for Soft X-ray Imager onboard the NeXT satellite
Shin-ichiro Takagi, Takeshi Go Tsuru, Tatsuya Inui +10
NeXT (New X-ray Telescope) is the next Japanese X-ray astronomical satellite mission after the Suzaku satellite. NeXT aims to perform wide band imaging spectroscopy. Due to the suc…
Suzaku Detection of Extended/Diffuse Hard X-Ray Emission from the Galactic Center
Takayuki Yuasa, Ken-ichi Tamura, Kazuhiro Nakazawa +12
Five on-plane regions within +/- 0.8deg of the Galactic center were observed with the Hard X-ray Detector (HXD) and the X-ray Imaging Spectrometer (XIS) onboard Suzaku. From all re…
X-Ray Spectroscopy of SN 1006 with Suzaku
Hiroya Yamaguchi, Katsuji Koyama, Satoru Katsuda +7
We report on observations of SN 1006 with the X-ray Imaging Spectrometers (XIS) on board Suzaku. We firmly detected K-shell emission from Fe, for the first time, and find that the…
