Tamura, Takayuki, Maeda, Y., Mitsuda, K., Fabian, A. C., Sanders, J. S., Furuzawa, A., ...
The results from Suzaku observations of the central region of the Perseus cluster are presented. Deep exposures with the X-ray Imaging Spectrometer provide high quality X-ray spectra from the...
The Evolution of Galaxy Clusters Across Cosmic Time (2009)
Arnaud, M., Bohringer, H., Jones, C., McNamara, B., Ohashi, T., Patnaude, D., ...
The large scale structure of the present Universe is determined by the growth of dark matter density fluctuations and by the dynamical action of dark energy and dark matter. While much progress has...
Doppler-Broadened Iron X-ray Lines from Tycho's Supernova Remnant (2009)
Furuzawa, A., Ueno, D., Hayato, A., Ozawa, M., Tamagawa, T., Bamba, A., ...
We use \suzaku observations to measure the spatial variation of the Fe K$\alpha$ line with radius in the \tycho supernova remnant. The Fe line widths show a significant decrease from a FWHM value of...
Ishisaki, Y., Maeda, Y., Fujimoto, R., Ozaki, M., Ebisawa, K., Takahashi, T., ...
We have developed a framework for the Monte-Carlo simulation of the X-Ray Telescopes (XRT) and the X-ray Imaging Spectrometers (XIS) onboard Suzaku, mainly for the scientific analysis of spatially...
DIOS: the Diffuse Intergalactic Oxygen Surveyor (2006)
Ohashi, T., Ishida, M., Sasaki, S., Ishisaki, Y., Mitsuda, K., Yamasaki, N. Y., ...
We present our proposal for a small X-ray mission DIOS (Diffuse Intergalactic Oxygen Surveyor), consisting of a 4-stage X-ray telescope and an array of TES microcalorimeters, cooled with mechanical...
Spectroscopic studies on impurity transport of core and edge plasmas in LHD (2006)

ASCA and XMM-Newton Observations of A2029 (2005)
Miyoshi, S., Tanaka, N., Yoshimura, M., Yamashita, K., Furuzawa, A., Futamura, T., ...
The X-ray data of A2029 obtained with XMM-Newton show no evidence of an embedded AGN in the central region of this cluster, which was suggested from the analysis of restored ASCA image data, although...
Locating the Warm-Hot Intergalactic Medium in the Simulated Local Universe (2004)
Yoshikawa, K., Dolag, K., Suto, Y., Sasaki, S., Yamasaki, N. Y., Ohashi, T., ...
We present an analysis of mock spectral observation of warm-hot intergalactic medium (WHIM) using a constrained simulation of the local universe. The simulated map of oxygen emission lines from local...
Future Japanese missions for the study of warm-hot intergalactic medium (2004)
Ohashi, T., Ishida, M., Sasaki, S., Ishisaki, Y., Mitsuda, K., Yamasaki, N. Y., ...
We present our proposal for a small X-ray mission DIOS (Diffuse Intergalactic Oxygen Surveyor) to perform survey observations of warm-hot intergalactic medium using OVII and OVIII emission lines....
Spatial Distributions of A3558 in the Core Region of the Shapley Supercluster (2003)
Akimoto, F., Kondou, K., Furuzawa, A., Tawara, Y., Yamashita, K.
The core region is dominated by three rich Abell clusters and two poor clusters. Their spatial distributions of gas temperature and metal abundance provide us with information on the interactions and...
X-ray calibration of the telescopes on board ASTRO-E satellite (1999)

ASCA and ROSAT observations of distant massive cooling flows (1996)
Allen, S. W., Fabian, A. C., Edge, A. C., Bautz, M. W., Furuzawa, A., Tawara, Y.
We present the results from a detailed ASCA/ROSAT X-ray study of three distant, massive cooling flows; Zwicky 3146 (z=0.291), Abell 1835 (z=0.252) and E1455+223 (Zwicky 7160; z=0.258). Using...
ABELL 2163: Temperature, Mass, and Hydrostatic Equilibrium (1995)
Markevitch, M., Mushotzky, R., Inoue, H., Yamashita, K., Furuzawa, A., Tawara, Y.
Using ASCA data, we have measured the electron temperature in A2163 out to 1.5h^{-1} Mpc (10a_x) from the center, in three radial bins. The temperatures are 12.2+1.9-1.2 keV, 11.5+2.7-2.9 keV and...
