Quantized redshifts: A status report

The current status of a continuing programme of tests for redshift periodicity or 'quantization' of nearby bright galaxies is described. So far the redshifts of over 250 galaxies with high-precision HI profiles have been used in the study. In consistently selected sub-samples of the datasets of sufficient precision examined so far, the redshift distribution has been found to be strongly quantized in the galactocentric frame of reference. The phenomenon is easily seen by eye and apparently cannot be ascribed to statistical artefacts, selection procedures or flawed reduction techniques. Two galactocentric periodicities have so far been detected, 71 .5km s^sup -1^ in the Virgo cluster, and 37. 5km s^sup -1^ for all other spiral galaxies within 2600km s^sup -1^. The formal confidence levels associated with these results are extremely high.[PUBLICATION ABSTRACT]
