Scientific paper

In the third of a series of papers on large-scale structures behind the southern Milky Way, we report here on redshifts obtained at the South African Astronomical Observatory (SAAO) in the Great Attractor region (318°<~l<~340°, |b|<=10°, Woudt, 1998, Ph. D. Thesis, University of Cape Town). This region encompasses the peak in the reconstructed mass density field, associated with the Great Attractor (Kolatt et al., 1995MNRAS.275..797K, Dekel et al., 1999ApJ...522....1D) and covers the crossing of the Supergalactic Plane with the Galactic Plane. Our deep optical galaxy search in the Zone of Avoidance (ZOA) in this region (Woudt, 1998, Ph. D. Thesis, University of Cape Town) has resulted in the detection of 4423 galaxies with observed diameters larger than 0.2arcmin. We have obtained reliable redshifts for 309 galaxies of the 4423 galaxies with the ``Unit'' spectrograph (first with a Reticon, then with a CCD detector) at the 1.9-m telescope of the SAAO. An additional 13 tentative redshifts are presented.
