This award will support a two-year U.S.-Japan cooperative research project between Professor Jeremiah Ostriker, Princeton University Observatory, and Professor Humitaka Sato, Department of Physics, Kyoto University. The project, which will include Professor Edwin Turner of the Princeton University Observatory as co-investigator on the U.S. side, brings together American and Japanese theoretical astrophysicists to study problems connected with the formation of galaxies and cosmic large scale structure. On the Japanese side, the research group includes scientists from the National Astronomical Observatory and the Tokyo Metropolitan University as well as Kyoto University. Among the studies on galaxy formation to be investigated are: imprints on the microwave background, phase transition generated structure formation, non-zero cosmological constant cosmologies, the relation of the intergalactic medium to background radiation fields, quasar statistics, structure formation by Doppler instability, gravitational lens statistics, phase transitions in the early universe, and related topics. Most of these projects will emphasize physics other than the purely gravitational interactions that have been studied most thoroughly in the past. It is hoped that this joint study will lead to more permanent contacts between the two research communities.

该奖项将支持为期两年的美国-日本合作社 普林斯顿大学的Jeremiah Ostriker教授 大学天文台和Humitaka Sato教授， 京都大学物理学系教授。 该项目将包括 普林斯顿大学天文台的埃德温·特纳教授作为 美国方面的共同调查员，汇集了美国和 日本理论天体物理学家研究问题连接 星系和宇宙大尺度结构的形成。 日本方面，研究小组包括来自 国家天文台和东京都 以及京都大学。 有待研究的星系形成研究包括： 在微波背景上留下印记， 结构形成，非零宇宙学常数宇宙学， 星系际介质与背景辐射的关系 场，类星体统计，多普勒不稳定性引起的结构形成， 引力透镜统计，早期宇宙的相变， 和相关主题。 这些项目中的大多数将强调物理 除了纯粹的引力相互作用， 过去研究得最透彻。 希望这次联合 这项研究将使两国之间建立更长期的联系。 研究社区。
