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.

这项在Eotvos大学Sandor Szalay博士和Lick Obsvatoration的David C. Koo博士之间的匈牙利联合基金下的这项US-Hust Research项目的主要目标是在理解宇宙结构的理解方面取得了重大进步。 当前对宇宙大规模结构的观察结果比以前想象的要大得多。 对星系的深度红移调查，朝北和南银河杆的“铅笔”几何形状表明，沿着视线的巨大聚类在超过100 mpc的尺度上，具有挑衅性的规律性。 这样的超级流行者的存在和分布对宇宙学具有深远的影响，但是这些观察结果只有在呈现压倒性证据后才获得普遍接受。 这些研究人员将进行新的观察结果：从现有的唯一数据中提取更多信息，更详细地建立统计错误，研究预测的效果，结构的横向范围，并寻找引力输入的迹象。 宇宙学项目实现了计划的目标，即通过使美国和东欧的主要专家能够将互补才能和汇总研究资源结合在一起，以促进科学知识。
