项目摘要

The Present research project "Relativistic Sunyaev-Zeldovich. Effect for Clusters of Galaxies" has successfully produced fruitful research results. First of all, we held International Workshop "Cosmology with SZ and X-Ray Observatories" at Sophia University for the period 2005 March 5-6. We invited 5 overseas researchers: K. Grainge (Cambridge), L Lamagna (Rome), L Knox (University of California, Davis), C. Li (Taipei), and J. Mohr (Illinois). The workshop turned out to be extremely successful. During the course of this research project we published 12 research papers in the refereed journals. The most recent published paper "An Improved Formula for the Relativistic Corrections to the Kinematical Sunyaev-Zeldovich Effect" (Nuovo Cimento, 121B, 487-500) summarizes most of our theoretical results. In this paper we have shown that the analytic results obtained by the Fokker-Planck expansion method agrees with the results obtained by the numerical integration of the Boltzmann equation with the accuracy better than 10-5 in the Rayleigh-Jeans regime. Our theoretical results are being used by the observers for their analysis of the Sunyaev-Zeldovich effect observations. In conclusion, the present research project "Relativistic Sunyaev-Zeldovich Effect fur Clusters of Galaxies" has achieved its initial prospective goal This evaluation is evidenced by the fact that the present head investigator was invited to give a lecture at the prestigious International School of Physics " Enrico Fermi" Course 159 held in Varenna, Italy, for the period 2004July 6-16.

目前的研究项目“相对论Sunyaev-Zeldovich。星系团效应”已成功取得了丰硕的研究成果。首先，我们于2005年3月5日至6日在上智大学举办了“SZ和X射线天文台宇宙学”国际研讨会。我们邀请了 5 名海外研究人员：K. Grainge（剑桥）、L Lamagna（罗马）、L Knox（加州大学戴维斯分校）、C. Li（台北）和 J. Mohr（伊利诺伊州）。研讨会非常成功。在本研究项目期间，我们在参考期刊上发表了 12 篇研究论文。最近发表的论文“An Improve Formula for the Relativistic Corrections to the Kinematical Sunyaev-Zeldovich Effect”（Nuovo Cimento，121B，487-500）总结了我们的大部分理论结果。本文表明，Fokker-Planck展开法得到的解析结果与Boltzmann方程数值积分得到的结果一致，在Rayleigh-Jeans体系中精度优于10-5。观察者正在使用我们的理论结果来分析 Sunyaev-Zeldovich 效应观测结果。综上所述，目前的研究项目“星系团的相对论孙亚耶夫-泽尔多维奇效应”已经达到了最初的预期目标，本次研究的负责人受邀到著名的国际物理学院进行讲座就证明了这一评价。 Enrico Fermi”课程 159 在意大利瓦伦纳举行，时间为 2004 年 7 月 6 日至 16 日。
