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…

Lauro Moscardini, Sabino Matarrese, Sabrina De Grandi +1
We analyse the spatial clustering properties of the RASS1 Bright Sample, an X-ray flux-limited catalogue of galaxy clusters selected from the southern part of the All-Sky S…
Measuring and Modelling the Redshift Evolution of Clustering: the Hubble Deep Field North
Stephane Arnouts, Stefano Cristiani, Lauro Moscardini +4
(abridged) The evolution of galaxy clustering from z=0 to z=4.5 is analyzed using the angular correlation function and the photometric redshift distribution of galaxies brighter th…
The Clustering of Lyman-break Galaxies
Peter Coles, Francesco Lucchin, Sabino Matarrese +1
We calculate the statistical clustering of Lyman-break galaxies predicted in a selection of currently-fashionable structure formation scenarios. These models are all based on the c…
Excursion set approach to the clustering of dark matter haloes in Lagrangian space
Cristiano Porciani, Sabino Matarrese, Francesco Lucchin +1
We present a stochastic approach to the spatial clustering of dark matter haloes in Lagrangian space. Our formalism is based on a local formulation of the `excursion set' approach…

We analyse the effect of two relevant physical constraints on the mass multiplicity function of dark matter halos in a Press--Schechter type algorithm. Considering the random--walk…
The epoch of structure formation in blue mixed dark matter models
Stefano Borgani, Francesco Lucchin, Sabino Matarrese +1
Recent data on the high--redshift abundance of damped Ly systems are compared with theoretical predictions for `blue' (i.e. ) Mixed Dark Matter models. The results show tha…
Observational constraints on blue primordial spectra

Recently, there has been growing interest on primordial ``blue" () perturbation spectra, motivated both by a composite set of observational data on large scales and from the p…
