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.

这个由厄特沃斯大学的Sandor Szalay博士和Lick天文台的David C.Koo博士组成的匈牙利联合基金的美国-匈牙利研究项目的主要目标是在理解宇宙结构方面取得重大进展。目前对宇宙大尺度结构的观察表明，在比之前认为的更大的尺度上存在不均匀。对具有铅笔束几何形状的星系朝南北极进行的深度红移调查表明，沿视线方向有强烈的星团聚集，尺度超过100Mpc，具有挑衅性的规律性。这种超星系团的存在和分布对宇宙学有着深远的影响，但只有在提出了压倒性的证据后，这些观测才会得到普遍接受。这些研究人员将进行新的观测：从现有的独特数据中提取更多信息，更详细地建立统计误差，研究投影的影响，结构的横向范围，并寻找引力坠落的迹象。这个宇宙学项目通过使美国和东欧的顶尖专家能够将互补的人才结合在一起，并在相互感兴趣和能力很强的领域汇集研究资源，实现了促进科学知识的计划目标。
