U.S.-Japan Cooperative Research: Physical Processes in Galaxy and Large Scale Structure Formation

该奖项将支持普林斯顿大学天文台的Jeremiah Ostriker教授和京都大学物理系的Humitaka Sato教授之间为期两年的美日合作研究项目。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研究员，将美国和日本的理论天体物理学家聚集在一起，研究与星系形成和宇宙大规模结构有关的问题。在日本方面，研究小组包括来自国立天文台、东京都大学和京都大学的科学家。待研究的星系形成研究包括：微波背景上的印记、相变产生的结构形成、非零宇宙常数宇宙学、星系间介质与背景辐射场的关系、类星体统计、多普勒不稳定性导致的结构形成、引力透镜统计、早期宇宙的相变以及相关主题。这些项目中的大多数将强调物理学，而不是过去研究得最彻底的纯粹的引力相互作用。希望这项联合研究将导致两个研究界之间更持久的联系。

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.
