Abstract

We present initial results from a redshift survey carried out with the Low Resolution Imaging Spectrograph on the 10 m W. M. Keck Telescope of a field 14.6 arcmin^2 in solid angle. In the redshift distribution of the 106 extragalactic objects in this sample we find five strong peaks, with velocity dispersions of ~500 km s^(-1). There is evidence for a nonuniform areal density of objects in at least two peaks. These peaks have characteristics (velocity dispersions, density enhancements, spacing, and spatial extent) similar to those of nearby galaxy structures (e.g., walls and clusters), and these are expected in a survey of this kind. We suggest that the prominence of these structures in our survey relative to that in other surveys can be attributed to our K selection and dense sampling.
