Dynamical properties of a family of collisionless models of elliptical galaxies
G. Bertin, M. Trenti
N-body simulations of collisionless collapse have offered important clues to the construction of realistic stellar dynamical models of elliptical galaxies. Such simulations confirm…

Slow evolution of elliptical galaxies induced by dynamical friction. I. Capture of a system of satellites
G. Bertin, T. Liseikina, F. Pegoraro
The main goal of this paper is to set up a numerical laboratory for the study of the slow evolution of the density and of the pressure tensor profiles of an otherwise collisionless…
