Periodicity in the redshift distribution of quasi stellar objects     

Debiprosad Duari 《Journal of Astrophysics and Astronomy》1997,18(4):441-447

There have been claims, from time to time that there are periodicities in the redshift distribution of quasistellar objects. These claims are examined from various statistical angles for the 2164 QSO redshifts available in the latest compilation by Hewitt& Burbidge (1990). The statistical tests reveal moderate to strong evidence for periodicities ξ = 0.0565 and 0.01270-0.129.  相似文献
