Monte-Carlo Simulator and Ancillary Response Generator of Suzaku XRT/XIS System for Spatially Extended Source Analysis
Y. Ishisaki, Y. Maeda, R. Fujimoto +31
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 analy…
Probing Warm-Hot Intergalactic Medium Associated with the Virgo Cluster using an Oxygen Absorption Line
R. Fujimoto, Y. Takei, T. Tamura +8
To detect a warm-hot intergalactic medium associated with the large-scale structure of the universe, we observed a quasar behind the Virgo cluster with XMM-Newton. With a net expos…
Temperature Map of the Perseus Cluster of Galaxies Observed with ASCA
T. Furusho, N. Y. Yamasaki, T. Ohashi +2
We present two-dimensional temperature map of the Perseus cluster based on multi-pointing observations with the ASCA GIS, covering a region with a diameter of ~2^\circ. By correcti…
A Possible Emission Feature in an X-ray Afterglow of GRB970828 as a Radiative Recombination Edge
A. Yoshida, M. Namiki, D. Yonetoku +6
A gamma-ray burst of 28 August 1997 was localized by the All-Sky Monitor on the Rossi XTE satellite and its coordinates were promptly disseminated. An ASCA followup started 1.17 da…
ASCA Observations of Temperature Structure and Metal Distribution in the Perseus Cluster of Galaxies
H. Ezawa, N. Y. Yamasaki, T. Ohashi +6
Large-scale distributions of hot-gas temperature and Fe abundance in the Perseus cluster have been studied with multi-pointing observations by the GIS instrument on ASCA. Within a…
ASCA Temperature Maps of Three Clusters of Galaxies Abell 1060, AWM7, and the Centaurus Cluster
T. Furusho, N. Y. Yamasaki, T. Ohashi +6
We present two-dimensional temperature maps of three bright clusters of galaxies Abell 1060, AWM7, and the Centaurus cluster, based on multi-pointing observations with the ASCA GIS…
