Basic properties of galaxy clustering in the light of recent results from the Sloan Digital Sky Survey
M. Joyce, F. Sylos Labini, A. Gabrielli +2
We discuss some of the basic implications of recent results on galaxy correlations published by the SDSS collaboration. In particular we focus on the evidence which has been recent…

Causality constraints on fluctuations in cosmology: a study with exactly solvable one dimensional models
A. Gabrielli, M. Joyce, B. Marcos +1
A well known argument in cosmology gives that the power spectrum (or structure function) of mass density fluctuations produced from a uniform initial state by physics which…

Generation of Primordial Cosmological Perturbations from Statistical Mechanical Models
A. Gabrielli, B. Jancovici, M. Joyce +3
The initial conditions describing seed fluctuations for the formation of structure in standard cosmological models, i.e.the Harrison-Zeldovich distribution, have very characteristi…
