The Scope of general relativity and cosmology

我们组织国内外研究广义相对论、宇宙膨胀及其相关学科（即数学物理、高能宇宙射线、星系形成等）的研究人员开展合作。在报告中可以看到的研究成果涵盖了广泛的领域。其中，对广义相对论的观测检验、引力坍缩、重力波、引力透镜、原始恒星天体形成、大尺度结构形成、星系形成及其演化、宇宙微波背景、宇宙学模型、暗物质、暴胀场景、量子宇宙学与超弦、核合成、伽玛射线暴、超高能宇宙射线等进行了研究。第一年，我们邀请了以色列希伯来大学的Y.Hoffman教授，做了一个关于宇宙观测数据分析的系列讲座。还讨论了可能的合作。该项目的许多研究人员在国际会议、地方会议以及日本物理学会和日本天文学会的年会上作了特邀报告。其中，杉山在国际天文学联合会学术研讨会上作了题为“宇宙微波背景测量宇宙参数”的特邀报告。第二年，我们在4月组织了第49届山田黑洞与高能天体物理学会议。佐藤是这次国际会议的主席。我们有140多名与会者，其中包括来自10个国家的30名特邀演讲者。在这次会议上，报告了与研究项目相关课题的最新成果，并进行了热烈的讨论。去年11月，我们还举办了一个关于广义相对论和宇宙学范围的地方会议，约有30名研究人员参加了会议。通过这些会议，我们希望我们能够创造这个领域的新趋势。为了展示我们的活动，我们中的许多人在各种会议上发言。例如，今年8月，Sugiyama在MPA/ESO宇宙学会议：大尺度结构的演化上做了一次受邀演讲。今年2月，中尾在南非相对论宇宙学会议上做了一次口头报告。少

We organize domestic and international collaborations in between researchers who are working on general relativity, expanding universe and their related subjects, i.e., mathematical physics, high energy cosmic rays, galaxy formation and so on. The research accomplishments which one can see in the report extend over a wide range. Among them, the observational test of the general relativity, gravitational collapse, gravity wave, gravitational lensing, primordial stellar object formation, large scale structure formation, formation of the galaxy and its evolution, cosmic microwave background, cosmological models, dark matter, inflation scenario, quantum cosmology and super string, nucleo-synthesis, gamma-ray burst and ultra-high energy cosmic rays have been studied.In the first year, we invited Professor Y.Hoffman from Hebrew University, Israel, and had a lecture series on data analysis of a cosmological observation. Possible collaborations were also discussed. Many of investigators of thi … More s project gave invited talks in international meetings together with local meetings and annual meetings of Japan Physical Society and Japan Astronomical Society. Among them, Sugiyama gave a invited talk "Determination of Cosmological Parameters by Cosmic Microwave Background" in IAU symposium.In the second year, we organized 49th Yamada Conference on Black Holes and High Energy Astrophysics in April. Sato was the chair of this international meeting. We had over 140 participants including 30 invited speakers from 10 countries. In this meeting, the most recent results on the subjects related to the research project were reported with hot discussions. We also had a local meeting on the scope of general relativity and cosmology in November, in which about 30 researchers attended. Through these meetings, we hope that we could create new trend of the field. In order to show our activity, many of us gave talks in various meetings. For example, Sugiyama gave a invited talk at MPA/ESO Cosmology Conference : Evolution of Large-Scale Structure, in August. Nakao gave a oral presentation at South African Relativistic Cosmology Conference in February. Less
