Abstract
Samples of 97 and 117 high-precision 21 cm redshifts of spiral galaxies within the Local Supercluster were obtained in order to test claims that extragalactic redshifts are periodic (P ~36 km s-1) when referred to the centre of the Galaxy. The power spectral density of the redshifts, when so referred, exhibits an extremely strong peak at 37.5 km s-1. The signal is seen independently with seven major radio telescopes. Its significance was assessed by comparison with the spectral power distributions of synthetic datasets constructed so as to closely mimic the overall properties of the real datasets employed; it was found to be real rather than due to chance at an extremely high confidence level. The signal was subjected to various tests for robustness such as partitioning of data, increase of strength with precision and size of sample, and stability of the correcting vector. In every respect tested, it behaved like a physically real phenomenon. The periodicity is particularly strong within small groups and associations of galaxies, showing no sign of an intrinsic spread ≳ 3 km s-1.
