                         gravitational clustering has greatly advanced in the last decades, 
                         in particular by improvements in numerical N-body simulations, the 
                         physics behind this process is not fully elucidated. Aims. The 
                         main goal of this work is the study of the possibility of a 
                         turbulent-like physical process in the formation of structures, 
                         galaxies and clusters of galaxies, by the action of gravity alone. 
                         Methods. We use simulation data from the Virgo Consortium, in ten 
                         redshift snapshots (from 0 to 10). From this we identify 
                         galaxy-sized and cluster-sized dark matter haloes, by using a FoF 
                         algorithm and applying a boundedness criterion, and study the 
                         gravitational potential energy spectra. Results. We find that the 
                         galaxy-sized halo energy spectrum follows closely a Kolmogorov 
                         power law, similar to the behaviour of dynamically turbulent 
                         processes in fluids. Conclusions. This means that the 
                         gravitational clustering of dark matter may admit a turbulent-like 
                         representation.",
