Grand Park Otaru Hotel), Otaru, Hokkaido Japan, The velocity diagnostics accessible through future X-ray satellites like ASTRO-H or IXO can be used to characterise non-thermal motions of the hot ICM within galaxy clusters. Allowing to account for the dynamical in addition to hydrostatic pressure support, this will be important for improving mass estimations and can be also used as selection criterion to identify non relaxed galaxy clusters. Therefore an analysis of the velocity structure of the ICM for simulated cluster-size haloes has been performed. In our work we note the presence of rotational patterns and find them to be an intermittent phenomenon strongly related to the internal dynamics of substructures: surprisingly the expected building-up of rotation due to mass assembly gets easily destroyed by passages of gas-rich substructures close to the central region., 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: AA0064574032, レポート番号: JAXA-SP-09-008E}, pages = {92--93}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Velocity Structure Diagnostics of X-Ray Galaxy Clusters}, volume = {JAXA-SP-09-008E}, year = {2010} }
