The secular evolution of self-gravitating systems over cosmic ages
Abstract.
Isolated, initially cold and spherically symmetric self-gravitating systems may give rise to a virial equilibrium state which is far from spherically symmetric, and typically triaxial, and with no-zero angular momentum. We discuss the main features of the dynamical mechanism that gives rise to such a quasi-stationary configuration stressing the potential interest from an observational point of view.
