Contribution

It presents a comprehensive observational analysis of galaxy distribution and introduces two independent methods for detecting large-scale structures in galaxy surveys.

Findings

Over 250 significant overdense structures identified.

Wide range of structures observed across redshifts up to 0.8.

Demonstrates effectiveness of density contrast mapping methods.

Abstract

The results of the study of the large-scale distribution of galaxies up to z ~0.8 in the field HS 47.5-22 on the basis of photometric data of the 1-meter Schmidt telescope of the BAO NAS Armenia are presented. The full sample contains 28,398 galaxies. Candidates for large-scale structures were determined using two independent methods for reconstructing density contrast maps in 57 narrow slices of the three-dimensional distribution of galaxies: adaptive aperture algorithm with smoothing and 2D Voronoi tessellation. We have identified more than 250 statistically significant overdense structures. The obtained results demonstrate a wide range of overdense structures over the full range of redshifts up to z ~0.8.
