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…
