Gas, Iron and Gravitational Mass in Galaxy Clusters: The General Lack of Cluster Evolution at z < 1.0
Hironori Matsumoto, Takeshi Go Tsuru, Yasushi Fukazawa +2
We have analyzed the ASCA data of 29 nearby clusters of galaxies systematically, and obtained temperatures, iron abundances, and X-ray luminosities of their intracluster medium (IC…
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…
