Testing the Velocity Field in Non--Scale-invariant Cold Dark Matter Models
TL;DR: In this article, the cosmic peculiar velocity field as traced by a sample of 1184 spiral, elliptical and S0 galaxies, grouped in 704 objects, was analyzed by calculating the bulk flow, cosmic Mach Number and velocity correlation function for this sample and for mock catalogs extracted from a set of N--body simulations.

Baryonic Acoustic Oscillations via the Renormalization Group
TL;DR: In this article, a semi-analytic approach to the computation of the non-linear power spectrum of dark matter density fluctuations is proposed, based on the Renormalization Group technique and can be applied to any underlying cosmological model.

Statistics of cosmological fields
Sabino Matarrese
- 01 May 2014
TL;DR: In this paper, the general problem of the statistics of the primordial curvature perturbation field in cosmology is reviewed and the search for non-Gaussian signatures in cosmological perturbations, originated from inflation in the early Universe is discussed both from the theoretical point of view and in connection with constraints coming from recent observations and future prospects for observing/constraining them.

TL;DR: Using the renormalization group (RG) technique in curved spacetime, the authors presented a theoretical motivation for spatial flatness of the universe using the cosmological perturbations.
Imprints of primordial non-Gaussianities in X-ray and SZ signals from galaxy clusters
Mauro Roncarelli,Lauro Moscardini,Enzo Branchini,Klaus Dolag,M. Grossi,Francesca Iannuzzi,Sabino Matarrese +6 more
TL;DR: In this paper, the distribution of galaxy clusters at different redshifts was studied and the results indicated that the effects introduced by a realistic amount of primordial non-Gaussianity are small when compared to the ones connected with current uncertainties in cosmological parameters.
