Abstract

The distribution of faint galaxies in a deep sample, down to a limiting magnitude of B ~ 21.5 in a region of some 30 square degrees of sky at the South Galactic Pole, is investigated. The sample was obtained from objective measurements made with the COSMOS automatic plate-scanning machine. The two-point angular correlation function shows positive correlation on scales out to ~1.5° and thereafter positive correlations on scales ~ 2.5° and ~ 5° indicating the presence of clustering in this sample on linear scales out to ~ 8h-1 Mpc and at ~ 13h-1 and ~ 27h-1 Mpc. On application of an algorithm for the detection of filamentary structure in the distribution of the galaxies, a negative result is obtained.
