Grand Park Otaru Hotel), Otaru, Hokkaido Japan, The metallicity distribution in the intracluster medium (ICM) of the Fornax cluster was studied with Suzaku and XMM-Newton. The abundances of O, Mg, Si, S, and Fe within a radius of 0.2r(sub 180) were measured with high accuracy with Suzaku. The abundance of Fe and the gas mass within a radius of 0.3r(sub 180) were measured with XMM-Newton. The oxygen and iron mass-to-light ratio (OMLR, IMLR) within 0.1r(sub 180) are over an order of magnitude lower than those of rich clusters and some relaxed groups of galaxies like the NGC 5044 group. The metal mass to light ratios outside 0.1r(sub 180) increases with radius, and may become comparable to those of the NGC 5044 group at 0.4 - 0.5r(sub 180). In the Fornax cluster, the asymmetric X-ray emission may point to large-scale dynamical evolution, which might have hampered the strong concentration of hot gas in the center., Meeting sponsors: The University of Tokyo, The Institute of Physical and Chemical Research, The Japan Society for the Promotion of Science, 資料番号: AA0064574148, レポート番号: JAXA-SP-09-008E}, pages = {384--385}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Suzaku and XMM-Newton Observations of the Metallicity Distribution in the Intracluster Medium of the Fornax cluster}, volume = {JAXA-SP-09-008E}, year = {2010} }
