X-ray Temperature and Mass Measurements to the Virial Radius of Abell 1413 with Suzaku
A. Hoshino, J. P. Henry, K. Sato +14
We present X-ray observations of the northern outskirts of the relaxed galaxy cluster A1413 with Suzaku, whose XIS instrument has the low intrinsic background needed to make measur…
Modeling and Reproducibility of Suzaku HXD PIN/GSO Background
Yasushi Fukazawa, Tsunefumi Mizuno, Shin Watanabe +26
Suzaku Hard X-ray Detector (HXD) achieved the lowest background level than any other previously or currently operational missions sensitive in the energy range of 10--600 keV, by u…
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…
