On the statistics of the gravitational field
A. Del Popolo
In this paper we extend Chandrasekhar and von Neumann's analysis of the statistics of the gravitational field to systems in which particles (e.g. stars, galaxies) are not homogeneo…
Tidal torques dynamical friction and the structure of clusters of galaxies
A. Del Popolo, M. Gambera
We study the joint effect of tidal torques and dynamical friction on the collapse of density peaks solving numerically the equations of motion of a shell of barionic matter falling…
Non radial motions and the large scale structure of the Universe
A. Del Popolo, M. Gambera
We study the effect of non-radial motions on the mass function, the VDF and on the shape of clusters of galaxies using the model introduced in Del Popolo & Gambera (1998a,b; 1999).…
The fluctuating gravitational field in inhomogeneous and clustered self-gravitating systems
A. Del Popolo
In this paper I extend the results of Ahmad & Cohen (1973), regarding the study of the probability distribution of the stochastic force in homogeneous gravitational systems, to inh…
Stochastic force in gravitational systems
A. Del Popolo
In this paper I study the probability distribution of the gravitational force in gravitational systems through numerical experiments. I show that Kandrup's (1980) and Antonuccio-De…
