Abstract
Redshift quantization in 21 cm redshifts for a set of Virgo cluster dwarf galaxies is examined using binomial statistics to evaluate the concentration of observed periodicities to values predicted by the LehtoTifft ninth-root rule. Quantization in accord with predictions is confirmed at the 99.8 confidence level for periodicities in the cosmic background rest frame. The method uses the set of all periods detected in the cluster by sampling periods in subsets of galaxies with various ranges of 21 cm profile width. The noise characteristics of period determinations are examined. Noise properties and the redshift range in the galaxy sample define the period range for which studies are valid. The method is compared with an alternative method which applies directly to power spectra of individual subsamples. When appropriate period ranges are used, consistent with noise properties of the data, the methods return equivalent results. 1 This work was carried out while on sabbatical leave from ...
