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…

Substructure effects on the collapse of density perturbations
A. Del Popolo, M. Gambera
We solve numerically the equations of motion for the collapse of a shell of baryonic matter, made of galaxies and substructure of , falling int…
