The primary objective of this US-Hungary research project under the Hungary Joint Fund between Dr. Sandor Szalay, Eotvos University, and Dr. David C. Koo, Lick Observatory, is to make major advances in the understanding of the structure of the universe. Current observations of the large scale structure of the universe show inhomogeneities on much larger scales than previously thought. Deep redshift surveys of galaxies with 'pencilbeam' geometry towards the North and South Galactic Poles indicate strong clustering along the line of sight, on scales exceeding 100 Mpc, with a provocative regularity. The existence and the distribution of such superclusters have profound implications for cosmology, but these observations will only gain a general acceptance after overwhelming evidence has been presented. These researchers will carry out new observations to: extract more information from the existing unique data, establish the statistical errors in more detail, study the effect of the projections, the transverse extent of the structures, and search for signs of gravitational infall. This project in cosmology fulfills the program objective of advancing scientific knowledge by enabling leading experts in the United States and Eastern Europe to combine complementary talents and pool research resources in areas of strong mutual interest and competence.

这项美国-匈牙利研究项目由匈牙利埃特沃斯大学 Sandor Szalay 博士和利克天文台 David C. Koo 博士之间的匈牙利联合基金资助，其主要目标是在对宇宙结构的理解方面取得重大进展。 目前对宇宙大尺度结构的观测显示，宇宙的不均匀性比之前想象的要大得多。 对南北银极具有“铅笔束”几何形状的星系进行的深度红移巡天表明，沿视线存在强烈的集群，规模超过 100 Mpc，具有令人兴奋的规律性。 这种超星系团的存在和分布对宇宙学具有深远的影响，但这些观察结果只有在提供压倒性的证据后才会获得普遍接受。 这些研究人员将进行新的观察：从现有的独特数据中提取更多信息，更详细地确定统计误差，研究预测的效果、结构的横向范围，并寻找重力坠落的迹象。 该宇宙学项目通过使美国和东欧的领先专家能够在共同感兴趣和能力强的领域结合互补人才并汇集研究资源，实现了推进科学知识的计划目标。
