Grand Park Otaru Hotel), Otaru, Hokkaido Japan, Galaxy groups are key tracers of galaxy evolution, cluster evolution, and structure formation, yet they are difficult to study at even moderate redshift. We have undertaken a project to observe a flux-limited sample of intermediate-redshift (0.1 < z < 0.5) group candidates identified by the XBootes Chandra survey. When complete, this project will nearly triple the current number of groups with measured temperatures in this redshift range. Here we present deep Suzaku/XIS and Chandra/ACIS follow-up observations of the first 10 targets in this project; all are confirmed sources of diffuse, thermal emission with derived temperatures and luminosities indicative of rich groups/poor clusters. By exploiting the multi-wavelength coverage of the XBootes/NOAO Deep Wide Field Survey (NDWFS) field, we aim to (1) constrain nongravitational effects that alter the energetics of the intragroup medium, and (2) understand the physical connection between the X-ray and optical properties of groups. We discuss the properties of the current group sample in the context of observed cluster scaling relations and group and cluster evolution and outline the future plans for this project., 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: AA0064574135, レポート番号: JAXA-SP-09-008E}, pages = {348--351}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Groups of Galaxies at Intermediate Redshift}, volume = {JAXA-SP-09-008E}, year = {2010} }
