The ASCA Medium Sensitivity Survey (the GIS Catalog Project): Source Counts and Evidence for Emerging Population of Hard Sources
Yoshihiro Ueda, Tadayuki Takahashi, Yoshitaka Ishisaki +2
We present first results from the ASCA Medium Sensitivity Survey (AMSS; or the GIS catalog project). From the serendipitous fields amounting to 106 degE-2, we determined the Log N…
Two-Phased Intra-Cluster Medium in the Centaurus Cluster of Galaxies
Yasushi Ikebe, Kazuo Makishima, Yasushi Fukazawa +4
ASCA and ROSAT data of the Centaurus cluster were analyzed. A central excess in the radial brightness profile is found in the hard energy band up to 10keV. This requires a deeper c…
ASCA Measurements of Metallicity and Temperature Distributions in Three Clusters: A4059, MKW 3s and 2A 0335+096
K. Kikuchi, T. Furusho, H. Ezawa +4
We present ASCA results on the distributions of metallicity and temperature in 3 bright near-by clusters: A4059, MKW 3s and 2A 0335+096. A significant gradient in the metal abundan…
