The Southern Sky Redshift Survey
Abstract
We have finished a redshift survey of galaxies selected from the ESO catalog and present here maps of the resulting space distribution. The sample consists of 2028 galaxies in an area of 1.75 sr with declination south of -17.5^deg^ and galactic latitude below -30^deg^. The sample diameter is limited with all galaxies having log [D(0)] greater than 0.1 where D(0) is a "face-on" diameter in arcminutes. The redshift sample is not complete at the smallest diameter, particularly for the later type galaxies, for which the surface brightness is very low; redshifts are available for 1657 of the galaxies. This survey provides useful information on large-scale structure to a depth of 120 h^-1^ Mpc (H_0_ = 100 h km s^-1^ Mpc^-1^). The galaxy distribution exhibits prominent filaments, sheets, and voids as seen in previous surveys, although there are no very rich clusters within the sample, the observed structure displays a diverse heterogeneity of morphology; some large-scale structures are highly subclustered, others are much more diffuse. Only a few of the more compact groups display conspicuous redshift space distortion. One large void in the foreground has an extent of 20 x 30 x 50 h^-1^ Mpc and appears quite promising for future searches of material less clustered than luminous galaxies.
