Scientific paper

The existence of quasar-redshift periodicity (QRP) is investigated, and a cosmological model is proposed to explain it. The power-spectrum analysis technique of Yu and Peebles (1969) is applied to various subsamples from the 1429-object catalog of Hewitt and Burbidge (1980); the results are presented in tables; and a QRP with respect to the quantity x = F(z, qO), where qO is the deceleration parameter, is confirmed. The QRP is explained as a remnant of acoustic density fluctuations in the early Big-bang universe, and a theoretical model is developed. The QRP data are found to be consistent with the model, and the estimated value of qO is estimated as greater than 0.5, suggesting a closed universe. For a universe with massive neutrinos, it is possible that qO = about 1.
