Abstract

The distribution of galaxies in the pencil-beam surveys of Broadhurst et al. which proved periodical across 8-10 consecutive steps in a flat dust model with q0=0.5 is found to reveal extended periodicity up to 16-17 phase-coherent steps, covering the total sample, in a flat, moderately inflationary model with q0=-0.5 (vacuum/dust ratio 2/1). In the latter model the vacuum component helps to reach the critical density and lengthens the expansion time-scale. It is shown that the explanation of the found periodicity as a consequence of space compactification as suggested by G. Paál twenty years ago in connection with apparent quasar periodicities is still possible.
