Predicting the Clustering of X-Ray Clusters
Lauro Moscardini, Sabino Matarrese, Francesco Lucchin +2
We present a theoretical model which aims at predicting the clustering properties of X-ray clusters in flux-limited surveys for different cosmological scenarios. The model uses the…

Non--Linear Dynamics of Irrotational Dust: Eulerian and Lagrangian Approaches
S. Matarrese, P. Catelan, F. Lucchin +3
Some recently proposed approximations to follow the non--linear evolution of collisionless matter perturbations in the universe are reviewed. The first one, called frozen--flow app…

Galaxy Velocity Field in Tilted Cold Dark Matter Models
F. Lucchin, S. Matarrese, L. Moscardini +1
We study the cosmic peculiar velocity field as traced by a sample of 1184 spiral, elliptical and S0 galaxies, grouped in 704 objects. We carry out a statistical analysis, by calcul…
