On the Problem of the Galaxy Alignment with Groups and Clusters

The study of the alignment of galaxy groups of the Tempel, Tago & Liivamagi (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.
