Hard X-ray Properties of the Merging Cluster Abell 3667 as Observed with Suzaku
Kazuhiro Nakazawa, Craig L. Sarazin, Madoka Kawaharada +10
Wide-band Suzaku data on the merging cluster Abell 3667 were examined for hard X-ray emission in excess to the known thermal component. Suzaku detected X-ray signals in the wide en…
Constraint of Non-thermal X-ray Emission from the On-going Merger Cluster Abell 3376 with Suzaku
Naomi Kawano, Yasushi Fukazawa, Sho Nishino +10
Clusters of galaxies are among the best candidates for particle acceleration sources in the universe, a signature of which is non-thermal hard X-ray emission from the accelerated r…
Suzaku Observation of HCG 62: Temperature, Abundance, and Extended Hard X-ray Emission Profiles
Kazuyo Tokoi, Kosuke Sato, Yoshitaka Ishisaki +14
We present results of 120 ks observation of a compact group of galaxies HCG~62 () with Suzaku XIS and HXD-PIN\@. The XIS spectra for four annular regions were fitted with…
X-Ray Study of Temperature and Abundance Profiles of the Cluster of Galaxies Abell 1060 with Suzaku
Kosuke Sato, Noriko Y. Yamasaki, Manabu Ishida +14
We carried out observations of the central and 20' east offset regions of the cluster of galaxies Abell 1060 with Suzaku. Spatially resolved X-ray spectral analysis has revealed te…
In-Orbit Performance of the Hard X-ray Detector on board Suzaku
M. Kokubun, K. Makishima, T. Takahashi +52
The in-orbit performance and calibration of the Hard X-ray Detector (HXD) on board the X-ray astronomy satellite Suzaku are described. Its basic performances, including a wide ener…
Hard X-ray Detector (HXD) on Board Suzaku
T. Takahashi, K. Abe, M. Endo +66
The Hard X-ray Detector (HXD) on board Suzaku covers a wide energy range from 10 keV to 600 keV by combination of silicon PIN diodes and GSO scintillators. The HXD is designed to a…
Suzaku Observations of the Centaurus Cluster: Absence of Bulk Motions in the Intracluster Medium
Naomi Ota, Yasushi Fukazawa, Andrew C. Fabian +13
The Centaurus cluster (z=0.0104) was observed with the X-ray Imaging Spectrometer (XIS) onboard the Suzaku X-ray satellite in three pointings, one centered on the cluster core and…
Scaling Mass Profiles around Elliptical Galaxies Observed with Chandra and XMM-Newton
Y. Fukazawa, J. G. Betoya-Nonesa, J. Pu +2
We investigated the dynamical structure of 53 elliptical galaxies, based on the {\it Chandra} archival X-ray data. In X-ray luminous galaxies, a temperature increases with radius a…
Chandra X-Ray Spectral Analysis of Cooling Flow Clusters, 2A 0335+096 and Abell 2199
Naomi Kawano, Akimitsu Ohto, Yasushi Fukazawa
We report on a spatially resolved analysis of Chandra X-ray data on a nearby typical cooling flow cluster of galaxies 2A 0335+096, together with A 2199 for a comparison. As recentl…
Extended Thermal X-ray Emission from the Spiral-Dominant Group of Galaxies HCG 57
Yasushi Fukazawa, Naomi Kawano, Akimitsu Ohto
We observed a group of galaxies, HCG 57, with ASCA. Regardless that their member galaxies are dominated by spiral galaxies, we detected extended thermal X-ray emission that is attr…
