RUI: Galaxy Morphology, Interactions and Aggregation

摘要霍夫曼，G.将进行射电天文学观测和分析，以继续长期研究星系如何从小星系群到超星系团在各种尺度上聚集，研究特定形态类型星系的性质和特性，以及影响HI盘最外边缘的物理过程。 将分析来自阿雷西博天文台的两个星系样本的数据。 将对阿雷西博望远镜十倍距离范围内所有星系群的微弱候选成员进行观测和分析，以研究塔利-费舍尔关系对较暗天体的扩展，获得更精确的星系群距离，并研究单个星系群的动力学以及本地超星系团和更遥远的质量集中对它们产生的潮汐影响。 ***

ABSTRACT Hoffman, G. Lyle AST-9316213 Radioastronomical observations and analyses will be made to continue a long-term study of how galaxies aggregate on various scales from small groups through superclusters, of the nature and properties of particular morphological types of galaxies, and physical processes affecting the outermost edges of HI disks. Data from the Arecibo Observatory for two samples of galaxies will be analyzed. Observations of faint candidate members of all groups within the declination range of the Arecibo telescope will be observed and analyzed to study the extension of the Tully-Fisher relation to fainter objects, to obtain even more precise distances to the groups, and to investigate the dynamics of the individual groups as well as the tidal influences on them produced by the Local Supercluster and more distant mass concentrations. ***
