Superclusters and pencil-beam surveys: The origin of large-scale periodicity

Research output: Contribution to journalReview articlepeer-review

It is shown that the apparent ∼130 h-1 Mpc periodic distribution of galaxies recently observed in narrow pencil-beam surveys originates in known large-scale superclusters, The superclusters, covering the high-latitude sky to z ≤ 0.08, show the same peaks that appear in the narrow-beam survey. These results suggest a network structure of large (∼100 h-1 Mpc) supercluster surfaces (walls) surrounding low-density regions. The apparent periodicity is expected to diminish when averaged over different directions.
