Non radial motions and the shapes and the abundance of clusters of galaxies
A. Del Popolo, M. Gambera
We study the effect of non-radial motions on the mass function, the velocity dispersion function (hereafter VDF) and on the shape of clusters of galaxies using the model introduced…
Density profiles of dark matter halos in an improved Secondary Infall model
A. Del Popolo, M. Gambera, E. Recami +1
In this paper we calculate the density profiles of virialized halos both in the case of structure evolving hierarchically from a scale-free Gaussian delta-field having a power spec…
Non-local bias and the problem of large-scale power in the Standard Cold Dark Matter model
A. Del Popolo, Y. Takahashi, H. Kiuchi +1
We study the effect of non-radial motions, originating from the gravitational interaction of the quadrupole moment of a protogalaxy with the tidal field of the matter of the neighb…
Kuiper Belt evolution due to dynamical friction
A. Del Popolo, E. Spedicato, M. Gambera
In this paper we study the role of dynamical friction on the evolution of a population of large objects ( g) at heliocentric distances AU in the Kuiper Belt. We sh…
