Large-Scale Structure Of Universe, Galaxies: Distances And Redshifts

Scientific paper

We have extended the CfA Redshift Survey to low galactic latitudes to investigate the relation between the Great Wall in the North Galactic Cap and the Perseus-Pisces chain in the South Galactic Cap. We present redshifts for 2020 galaxies in the Catalogue of Galaxies and of Clusters of Galaxies (Zwicky et al. 1961-68, CGCG) in the following regions: 4^h^ <= α <= 8^h^, 17^h^ <= α <= 20^h^, 0^deg^ <= δ <= 45^deg^. In these regions, the redshift catalogue includes 1664 galaxies with B(0) <= 15.5 (of which 820 are newly measured) and is 97% complete. We also include redshifts for an additional 356 galaxies in these regions with B(O) > 15.5; of these, 148 were previously unmeasured. The CGCG samples the galaxy distribution down to b_II_ = 10^deg^. In this paper, we discuss the acquisition and reduction of the spectra, and we examine the qualitative features of the redshift distribution. The Great Wall and the Perseus-Pisces chain are not simply connected across the Zone of Avoidance. These structures, which at first appear to be coherent on scales of ~100 h^-1^ Mpc or more, actually form the boundaries of neighboring voids of considerably smaller scale, approximately 50h^-1^ Mpc. The structures delineated by our optically-selected sample are qualitatively similar to those detected by the far-infrared-selected IRAS 1.2 Jansky Survey (Fisher et al. 1995). Although the IRAS survey probes more deeply into the Zone of Avoidance, our optically-selected survey provides better sampling of structures at b_II_ >= 10^deg^.
