X-Ray Reflection Nebulae with Large Equivalent Widths of Neutral Iron Ka Line in the Sgr C Region
Hiroshi Nakajima, Takeshi Go Tsuru, Masayoshi Nobukawa +5
This paper reports on the first results of the Suzaku observation in the Sgr C region. We detected four diffuse clumps with strong line emission at 6.4keV, Ka from neutral or low-i…
Spectral transitions of an ultraluminous X-ray source, NGC 2403 Source 3
Naoki Isobe, Kazuo Makishima, Hiromitsu Takahashi +8
Suzaku observation of an ultraluminous X-ray source, NGC 2403 Source 3, performed on 2006 March 16--17, is reported. The Suzaku XIS spectrum of Source 3 was described with a multi-…
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…
Iron and Nickel Line Diagnostics for the Galactic Center Diffuse Emission
Katsuji Koyama, Yoshiaki Hyodo, Tatsuya Inui +14
We have observed the diffuse X-ray emission from the Galactic center (GC) using the X-ray Imaging Spectrometer (XIS) on Suzaku. The high-energy resolution and the low-background or…
Suzaku Observations of HESS J1616-508: Evidence for a Dark Particle Accelerator
Hironori Matsumoto, Masaru Ueno, Aya Bamba +15
We observed the bright unidentified TeV gamma-ray source HESS J1616-508 with the X-ray Imaging Spectrometers onboard the Suzaku satellite. No X-ray counterpart was found to a limit…
Chandra Deep X-ray Observation of a Typical Galactic Plane Region and Near-Infrared Identification
K. Ebisawa, M. Tsujimoto, A. Paizis +13
Using the Chandra Advanced CCD Imaging Spectrometer Imaging array (ACIS-I), we have carried out a deep hard X-ray observation of the Galactic plane region at (l,b) ~ (28.5, 0.0), w…
A Chandra Deep X-ray Exposure on the Galactic Plane and Near Infrared Identification
K. Ebisawa, A. Paizis, T. J. -L. Couvoisier +13
Using the Chandra ACIS-I instruments, we have carried out a deep X-ray observation on the Galactic plane region at (l,b) ~ (28.5, 0.0), where no discrete X-ray sources have been kn…
Galactic X-ray Survey
K. Ebisawa, S. Yamauchi, A. Bamba +2
We review highlights of the results obtained from recent Galactic X-ray survey observations, in particular ASCA Galactic center and plane survey and our Chandra deep survey on the…
Diffuse X-rays in the Galactic center region -- The zoo of iron line clumps, non-thermal filaments and hot plasmas --
Aya Bamba, Hiroshi Murakami, Atsushi Senda +3
This paper reports the diffuse X-ray features around the Galactic center observed with Chandra. We confirm the ASCA and Ginga discoveries of the large-scale thin-thermal plasma wit…
Unusual diffuse X-ray source in the Galactic center region
Atsushi Senda, Hiroshi Murakami, Katsuji Koyama
We report the ASCA and Chandra discovery of a diffuse X-ray source in the Galactic center region. The X-ray spectrum is fitted with a non-equilibrium ionization (NEI) plasma model…
