Scientific paper

The result by Broadhurst et al. (1990) showing a striking nearly periodic galaxy redshift distribution in a narrow pencil-beam survey, is explained within the Voronoi cellular model of clustering of galaxies. Galaxies, whose luminosities are selected from a Schechter luminosity function, are placed randomly within the walls of this cellular model. Narrow and deep, magnitude-limited, pencil-beam surveys through these structures are simulated. Some 15 percent of these beams show the observed regular pattern, with a spacing between the peaks of the order of (105-150)/h Mpc, but most pencil-beams show peaks in the redshift distribution without periodicity, so it is concluded that, even within a cellular universe, periodicity is not a common phenomenon.
