Density fluctuations on mm and Mpc scales

We will in this paper report on suggestive similarities between density fluctuation power versus wavenumber on small (mm) and large (Mpc) scales. The small scale measurements were made in fusion plasmas and compared to predictions from classical fluid turbulence theory. The data is consistent with the dissipative range of 2D turbulence. Alternatively, the results can be fitted to a functional f...

A comparative study of density fluctuations on mm and Mpc scales

We have in earlier work (Basse N P 2005 Phys. Lett. A 340 456) reported on intriguing similarities between density fluctuation power versus wavenumber on small (mm) and large (Mpc) scales. In this paper we expand upon our previous studies of small and large scale measurements made in fusion plasmas and using cosmological data, respectively. The measurements are compared to predictions from clas...

The Structure of the Universe on 100 Mpc Scales

Observational evidence for the presence of a preferred scale around 100 Mpc in the distribution of high-density regions in the Universe is summarised. Toy models with various degrees of regularity are analysed to understand better the observational data. Predictions of models which produce a feature on the initial power spectrum of matter are analysed and compared with new observational data on...
