Suzaku Constraints on the Soft and Hard Excess Emissions from Abell 2199
Madoka Kawaharada, Kazuo Makishima, Takao Kitaguchi +3
The nearby () cluster of galaxies Abell~2199 was observed by Suzaku in X-rays, with five pointings for ks each. From the XIS data, the temperature and metal ab…
Is the black hole in GX 339-4 really spinning rapidly?
S. Yamada, K. Makishima, Y. Uehara +7
The wide-band Suzaku spectra of the black hole binary GX 339-4, acquired in 2007 February during the Very High state, were reanalyzed. Effects of event pileup (significant within ~…
Suzaku Observation of the Radio Halo Cluster Abell 2319: Gas Dynamics and Hard X-ray Properties
Chika Sugawara, Motokazu Takizawa, Kazuhiro Nakazawa
We present the results of Suzaku observation of the radio halo cluster Abell 2319. The metal abundance in the central cool region is found to be higher than the surrounding region,…
X-ray Diagnostics of Thermal Conditions of the Hot Plasmas in the Centaurus Cluster
I. Takahashi, M. Kawaharada, K. Makishima +9
X-ray data of the Centaurus cluster, obtained with {\it XMM-Newton} for 45 ksec, were analyzed. Deprojected EPIC spectra from concentric thin shell regions were reproduced equally…
The origin of an extended X-ray emission apparently associated with the globular cluster 47 Tucanae
Takayuki Yuasa, Kazuhiro Nakazawa, Kazuo Makishima
Using the Suzaku X-ray Imaging Spectrometer, we performed a 130 ks observation of an extended X-ray emission, which was shown by ROSAT and Chandra observations to apparently associ…
Origin of Thermal and Non-Thermal Hard X-ray Emission from the Galactic Center
Vladimir Dogiel, Dmitrii Chernyshov, Takayuki Yuasa +10
We analyse new results of Chandra and Suzaku which found a flux of hard X-ray emission from the compact region around Sgr A (r ~ 100 pc). We suppose that this emission is ge…
