Scientific paper

Power spectral analysis was applied to the redshift distribution of the quasars associated with low-redshift galaxies. Periodicity is confirmed at a level of confidence above 99 percent, with a period of Delta-ln(1+z) = 0.206. This result is exactly the same as previously found for different quasar samples. The periodicity is not caused by any selection effect in the emission lines. The two phenomena, the periodicity in the redshift distribution and the association of quasars with low-redshift galaxies can both be rather well explained by a multiply-connected model of the universe.
