Constraints to cosmological parameters through clusters evolution
A. Del Popolo, N. Ercan
In this paper, I revisit the constraints obtained by several authors (Reichart et al. 1999; Eke et al. 1998; Henry 2000) on the estimated values of Omegam, n and sigma_8 in the lig…

X-ray temperature distribution function of clusters in presence of large non-radial motions
A. Del Popolo, M. Gambera
We consider the non-radial motions, originating in the outskirts of clusters of galaxies and we show how it may reduce the discrepancy between Cold Dark Matter (CDM) predicted X-ra…

Dark Matter Halos in a Secondary Infall Model
A. Del Popolo, M. Gambera
We calculate the density profiles of virialized halos in the case of structure evolving hierarchically from a scale-free Gaussian delta-field having a power spectrum $P(k)\propto k…
