The study of the alignment of galaxy groups of the Tempel, Tago & Liivamägi (2012) catalog showed that detection of the alignment of the group galaxies with the group orientation depends on the position angle of the studied group. Alignment is detected in groups the position angle of which approximately coincides with the average position angle of the group galaxies that is about 90° for all groups. The analysis of the alignment of clusters with known orientations shows the same: alignment is detected in clusters with position angle of the large axes of about 90°. Possibly the alignment of galaxy systems is due to a general gravitational or a magnetic field.

关于星系与群和星团对齐的问题

Tempel, Tago & Liivamägi (2012) 目录中星系群排列的研究表明，检测群星系与群方向的排列取决于所研究群的位置角度。在组中检测对齐，其位置角与所有组的群星系的平均位置角大约为 90° 重合。对已知方向的簇对齐的分析显示相同：在大轴位置角约为 90° 的簇中检测到对齐。星系系统的排列可能是由于一般的引力或磁场。
