Predictions of mixed non-Gaussian cosmological density fields for the cosmic microwave background radiation
Ana Paula Andrade, Carlos Alexandre Wuensche, Andre Luiz B. Ribeiro
We present simulations of the Cosmic Microwave Background Radiation (CMBR) power spectrum for a class of mixed, non-Gaussian, primordial random fields. We assume a skew positive mi…
Multiscaling and Nonextensivity of Large-scale Structures in the Universe
F. M. Ramos, C. A. Wuensche, A. L. B. Ribeiro +1
There has been a trend in the past decade to describe the large-scale structures in the Universe as a (multi)fractal set. However, one of the main objections raised by the opponent…
Small Deviations from Gaussianity and The Galaxy Cluster Abundance Evolution
A. L. B. Ribeiro, C. A. Wuensche, P. S. Letelier
We raise the hypothesis that the density fluctuations field which originates the growth of large scale structures is a combination of two or more distributions. By applying the sta…
